A Canadian WWI recruiting poster
The military history of Canada entails millennia of armed actions in the territory encompassing modern Canada, and the role of the Canadian military in conflicts and peacekeeping worldwide. For at least 10,000 years, the area that would become Canada was the site of intertribal wars among First Nation groups. Beginning in the 16th century, the arrival of Europeans led to conflicts with the Natives and among the colonizing Europeans in the New World. Starting in the 17th century, the region was the site of fighting between the French and the British for more than a century. New challenges soon arose when the northern colonies chose not to join the American Revolution and remained loyal to the British crown. Americans looked to extend their republic and launched an invasion in 1812. After Canada's independence, and amid much controversy, a fully-fledged Canadian military was created. Canada's links to Britain remained strong, and Canadian forces joined their British counterparts in the Boer War, the First and Second World Wars. Since the Second World War, Canada has been committed to multilateralism and has gone to war only within large multinational coalitions such as in the Korean War, the Gulf War, and the 2001 invasion of Afghanistan.



An M1A1 Abrams tank
A tank is a tracked and armoured combat vehicle designed primarily to destroy enemy ground forces by direct fire. A modern main battle tank, designed predominantly for combat, is the most powerful direct-fire land-based weapon. It is distinguished from other armoured fighting vehicles primarily by its heavy armour and armament. It can cross rough terrain and move relatively quickly in short bursts, but is power-, maintenance-, and ammunition-hungry and is not designed for sustained operations. Tanks were first used in World War I and have undergone many generations of design evolution since then. Tanks are now a fairly mature technology, but significant improvements continue to be made in tank subsystems.

The Battle of Leyte Gulf was a naval battle of the Pacific campaign of World War II, fought in the seas around the island of Leyte in the Philippines from October 23 to October 26, 1944. The Japanese intended to repel or destroy the Allied invasion of Leyte. Instead, the Allied navies inflicted a major defeat on the outnumbered Imperial Japanese Navy which finished it as a strategic force in the Pacific War. The battle is often considered to be the largest naval battle in history. Leyte Gulf was also the scene of the first use of kamikaze aircraft by the Japanese. The Australian heavy cruiser HMAS Australia was hit on 21 October, and organized suicide attacks by the "Special Attack Force" began on 25 October.



The 1453 Siege of Constantinople
A siege is a prolonged military assault on and blockade of a city or fortress with the intent of conquering by force or attrition. A siege occurs when an attacker encounters a city or fortress that refuses to surrender and cannot be easily taken by a frontal assault. Sieges usually involve surrounding the target and blocking the provision of supplies, typically coupled with artillery bombardment, sapping and mining to reduce fortifications. Sieges are as old as warfare itself, with towns in the Middle East from the dawn of civilization having city walls. However, with the advent of mobile warfare, one single fortified stronghold is no longer as decisive as it once was.

The Lord's Resistance Army is a rebel paramilitary group operating in northern Uganda, and as of February 2005 is engaged in an armed conflict against the Ugandan government. It is led by Joseph Kony, who proclaims himself a spirit medium and apparently wishes to establish a state based on his unique interpretation of Biblical millenarianism. The rebels have been accused of many atrocities in the area. It is estimated that around 20,000 children have been kidnapped by the group since 1987 for use as as soldiers and sex slaves. LRA practices such as mutilation, enforced prostitution and enlisting children under the age of 15 into armed groups are war crimes. The group abducts its members primarily from the Acholi people, but it lacks widespread support among the Acholis, who have been the victims of many of its tactics. The insurgency has been mainly contained to the region known as Acholiland, consisting of the districts of Kitgum, Gulu, and Pader, though since 2002 violence has overflowed into other districts, including Lira, Apac and Adjumani.



Chemical warfare is warfare using the toxic properties of chemical substances to kill, injure or incapacitate the enemy. Chemical warfare is distinct from the use of conventional weapons or nuclear weapons because the destructive effects of chemical weapons are not primarily due to any explosive force. The offensive use of living organisms or their toxic products (such as anthrax or botulin toxin) is not considered chemical warfare: their use is instead labelled biological warfare. Chemical weapons are classified as weapons of mass destruction by the United Nations, and their production and stockpiling was outlawed by the Chemical Weapons Convention of 1993.



A Coast Guard-manned LCVP disembarks troops at Omaha Beach
The Battle of Normandy in 1944, codenamed Operation Overlord, was the invasion of Nazi-occupied Western Europe by the Allies. The Normandy invasion began with overnight paratrooper and glider landings, massive air and naval bombardments, and an early-morning amphibious assault. It continued over more than two months, with campaigns to establish, expand, and eventually break out of the Allied beachheads. It concluded with the surrender of Paris and the fall of the Chambois pocket. Normandy is, to this day, one of the best-known battles of World War II. In common language, the expression "D-Day" is still used to refer to June 6, the starting date of the invasion and the opening day of the battle.



Franco-Venetian alliance decisively defeated the Holy League at the Battle of Marignano
The War of the League of Cambrai was a major conflict in the Italian Wars, occurring from 1508 to 1516. The principal participants of the war were France, the Papal States, and the Republic of Venice. Pope Julius II had intended that the war would curb Venetian influence in northern Italy, and had, to this end, created the League of Cambrai (named after Cambrai, where the negotiations took place), an alliance against the Republic that included, besides himself, Louis XII of France, Emperor Maximilian I, and Ferdinand I of Spain. Although the League was initially successful, friction between Julius and Louis caused it to collapse by 1510; Julius then allied himself with Venice against France. The Veneto-Papal alliance eventually expanded into the Holy League, which drove the French from Italy in 1512; disagreements about the division of the spoils, however, led Venice to abandon the alliance in favor of one with France. Under the leadership of Francis I, who had succeeded Louis to the throne, the French and Venetians would, through their victory at Marignano in 1515, regain the territory they had lost; the treaties of Noyon and Brussels, which ended the war the next year, would essentially return the map of Italy to the status quo of 1508.



Napoléon at the Battle of Austerlitz, by François Pascal Simon

The Battle of Austerlitz was a major engagement in the Napoleonic Wars during the War of the Third Coalition. It was fought on December 2, 1805 about four miles (6.4 km) east of the modern Czech town of Brno, then part of the Austrian Empire. The conflict involved forces of the recently formed First French Empire against the armies of the Russian Empire and the Austrian Empire. After nearly nine hours of fighting, the French troops, commanded by Emperor Napoleon I, managed to score a decisive victory over the Russo-Austrian army, commanded by Czar Alexander I. Despite difficult fighting in many sectors, the battle is often regarded as a tactical masterpiece. Austerlitz effectively brought the Third Coalition to an end.



German troops parade through Warsaw, Poland on October 5, 1939.

The Polish September Campaign was the conquest of Poland by the armies of Nazi Germany, the Soviet Union, and a small contingent of Slovakian forces during the Second World War. The campaign began on 1 September 1939 following a German-staged attack. This military operation, which saw the first use of Blitzkrieg tactics, marked the start of the Second World War in Europe as the invasion led Poland's allies, the United Kingdom and France, to declare war on Germany on September 3. On September 17, 1939, the Soviet Red Army invaded the eastern regions of Poland. The Soviets were acting in co-operation with Nazi Germany, carrying out their part of the secret appendix of the Molotov-Ribbentrop Pact (the division of Europe into Nazi and Soviet spheres of influence). The campaign ended on 6 October 1939, with Germany and the Soviet Union occupying the entirety of Poland.



A poison gas attack in World War I

The use of poison gas was a major military innovation of the First World War. The gases used ranged from tear gas to disabling chemicals such as mustard gas and killing agents like phosgene. The killing capacity of gas was limited — only 3% of combat deaths were due to gas — however, the proportion of non-fatal casualties was high and gas remained one of the soldier's greatest fears. Unlike most other weapons of the period, it was possible to develop effective countermeasures to gas and hence in the latter stages of the war, as the use of gas increased, in many cases its effectiveness was diminished.



Ships unload men and equipment one day after the landings
The Battle of Inchon was a decisive 15-day invasion and battle during the Korean War. The battle began on September 15, 1950, and ended around September 28. During the amphibious operation, U.S. Marines under the command of General Douglas MacArthur secured Inchon and broke North Korean control of the Pusan region through a series of landings in enemy territory. The Battle of Inchon ended a string of victories by the invading North Korean People's Army (NKPA) and began a counterattack by United Nations forces that led to the recapture of Seoul. The northern advance ended when China's People's Liberation Army entered the conflict in support of North Korea, and defeated UN forces at the Battle of Chosin Reservoir.



The FIS logo
The Algerian Civil War was an armed conflict between the Algerian government and various Islamist rebel groups which began in 1991. It is estimated to have cost over 100,000 lives. The conflict has effectively ended with a government victory, following the surrender of the Islamic Salvation Army and the defeat of the Armed Islamic Group. The conflict began in December 1991, when the government cancelled elections after the first round results had shown that the Islamic Salvation Front (FIS) party would win, citing fears that the FIS would end democracy. Islamist guerrillas rapidly emerged and began an armed campaign against the government and its supporters. They formed themselves into several armed groups, principally the Islamic Armed Movement (MIA), based in the mountains, and the Armed Islamic Group (GIA), based in the towns. The guerrillas initially targeted the army and police, but some groups soon started attacking civilians. The MIA and its allies, under attack from both sides, opted for a unilateral ceasefire with the government in 1997, while the GIA was torn apart by splits as various subdivisions objected to its new massacre policy. In 1999, following the election of a new president, Abdelaziz Bouteflika, a new law gave amnesty to most guerrillas, motivating large numbers to "repent" (as it was termed) and return to normal life. The violence declined substantially, with effective victory for the government.



American soldiers taking up defensive positions in the Ardennes
The Battle of the Bulge was the last major German offensive on the Western Front in World War II. It was intended that the German army would split the Allied line in half, capture Antwerp, sweep north and encircle and destroy four Allied armies, thus forcing them to negotiate for peace. Although unsuccessful, it nevertheless tied down huge amounts of Allied resources, and a slow response to the resulting gap in their lines erased months from their timetable. An alternative analysis is that the offensive allowed the Allies to severely deplete the cream of German army outside the defenses of the West Wall and in poor supply state, greatly easing the assault on Germany afterward. In numerical terms, it is the largest battle the United States Army has ever fought.



Capture of Jerusalem in 1099
The First Crusade was a crusade launched in 1095 by Pope Urban II to regain control of the sacred city of Jerusalem and the Christian Holy Land from Muslims. What started as a minor call for aid quickly turned into a wholesale migration and conquest of territory outside of Europe. Both knights and peasants from many different nations of western Europe, with little central leadership, travelled overland and by sea towards Jerusalem and captured the city in July 1099, establishing the Kingdom of Jerusalem and the other Crusader states. Although these gains lasted for fewer than 200 years, the Crusade was a major turning point in the expansion of Western power, and was the only crusade out of the many that followed to achieve its stated goal.



JMW Turner's 'Battle of Trafalgar' shows the last three letters of this famous signal
"England expects that every man will do his duty" was a signal sent by Admiral Horatio Nelson, 1st Viscount Nelson from his ship HMS Victory as the Battle of Trafalgar (1805) was about to commence. Trafalgar was the decisive naval engagement of the Napoleonic Wars. It gave the United Kingdom control of the seas, removing all possibility of a French invasion and conquest of Britain. The phrase has become extremely well-known in Britain as a result of Lord Nelson's fame and the importance of the Battle of Trafalgar in British history. The phrase is known so widely in Britain that it has entered the British popular consciousness. Today "England expects…", as an abbreviated version of the phrase, is often adapted for use in the media, especially in relation to the expectations for the victory of English sporting teams.



Portrait of Isaac Brock by John Wycliffe
Isaac Brock was a British major-general and administrator, who served in various parts of the Empire for nearly thirty years, serving in the Caribbean, Denmark, and elsewhere. During that time he challenged duelists, nearly died from fever, was injured in battle, faced both desertions and near mutinies, and also had the privilege of serving alongside Lord Nelson. However, he is best remembered for his actions while assigned to the Canadian colonies. Brock was assigned to Canada in 1802, eventually reaching the rank of Major-General. In this capacity, he was responsible for defending Canada from the United States during the War of 1812. While many in Canada and in England believed war could be averted, Brock began preparing the army, the militia, and the populace for what was to come. Thus, when war broke out, Canada was prepared, and quick victories at Fort Mackinac and in the Battle of Detroit crippled American invasion efforts, securing Brock's reputation as a brilliant leader and strategist. His death in the Battle of Queenston Heights was a crushing blow to British leadership. Brock's efforts earned him accolades, a knighthood, and the moniker "The Hero of Upper Canada".



Section of the Krag-Petersson
The Krag-Petersson rifle was the first repeating rifle adopted by the armed forces of Norway, and one of the first repeating arms adopted anywhere in the world. Developed by Ole Herman Johannes Krag, the action of the Krag-Petersson was uniquely actuated by the oversized hammer. Another distinguishing feature is that the cartridge rising from the magazine is not seated automatically, but has to be pushed into the breech of the rifle. Testing by the Norwegian military revealed that the Krag-Peterssen was a robust, accurate and quick firing weapon, and the Royal Norwegian Navy adopted the rifle in 1876. The rifle was also extensively tested by other nations, but not adopted. After being phased out around 1900, the remaining rifles were sold off to civilians, and often extensively rebuilt. Today it is so difficult to find one in original condition that the Krag-Petersson has been described as "the rifle everybody has heard about, but hardly anybody has ever seen". It was the first rifle designed by Ole H. J. Krag that was adopted by an armed force.



Battle Between the Monitor and Merrimac, by Kurz and Allison
The Battle of Hampton Roads was a naval battle of the American Civil War, taking place from March 8, 1862 to March 9, 1862, off Sewell's Point, a narrow place near the mouth of Hampton Roads, Virginia. As the war started, Union forces evacuating Norfolk burned the ships left behind. One was raised by the Confederates, renamed the CSS Virginia, and plated with iron—making it the first modern ironclad warship. On March 8, 1862, it sailed into Hampton Roads off Sewell's Point to challenge the blockading Union ships there, destroying several of them. The next day, it was engaged by the USS Monitor, a newly built Union ironclad. Although the battle itself was inconclusive, it is chiefly significant in naval history as the first battle between two powered ironclad warships, which came to be known as ironclads. Prior to then, warships were made primarily of wood. After the battle, ships and naval warfare changed dramatically, as nations around the world raced to convert their fleets to iron.



Stalin and Kliment Voroshilov salute a military parade in Red Square

The military history of the Soviet Union began in the early days following the 1917 October Revolution and the creation of the Russian Soviet Federated Socialist Republic, which joined with other former provinces of the Russian Empire to become the Union of Soviet Socialist Republics in 1922. In the 1940s, the Soviet Union took part in World War II, assisting in the defeat of Nazi Germany and militarily occupied many former Axis nations in eastern Europe, which formed its satellite states in the Soviet bloc. Following the end of World War II, the Soviet Union became one of two superpowers, rivaling the United States. The Cold War between the two nations led to Soviet military buildups, the arms race, and the Space Race. By the early 1980s, the Soviet armed forces were the world's largest by every measure—in number of weapons, in manpower, and in size of their military-industrial base. In the end, the Soviet Union fell in 1991 due to economic and political factors rather than due to military defeat.



A Medal of Honor from the late 19th century

The Medal of Honor is the highest military decoration awarded by the United States. It is awarded "for conspicuous gallantry and intrepidity at the risk of life, above and beyond the call of duty, in actual combat against an armed enemy force." Three different medals currently exist for each of the major branches of the U.S. armed forces: one each for the Army, Navy, and Air Force. Since the beginning of World War II, only 851 have been awarded, 525 of them posthumously. The rare soldier who wears the Medal of Honor is accorded special privileges that include higher pay, preference for their children at the U.S. military academies, and the respect and admiration of all other service-people. It is an informal rule that Medal of Honor recipients, regardless of rank, are saluted by all other service members, including the Commander-in-Chief. The Army Medal of Honor was first awarded during the American Civil War and was last officially awarded to Paul Ray Smith for action that occurred during the Iraq War in 2003.



Richard O'Connor
Richard O'Connor was a British Army general who commanded the Western Desert Force (WDF) in the early years of World War II. O'Connor was the field commander for Operation Compass, in which he and the WDF completely destroyed a much larger Italian army. This victory nearly drove the Axis from Africa entirely, and led Adolf Hitler to send the Deutsches Afrikakorps under Erwin Rommel, to try and reverse the situation. O'Connor was later captured and spent over two years in an Italian prisoner of war camp for senior officers. He made a number of escape attempts with General Sir Philip Neame and Lieutenant General Sir Adrian Carton De Wiart, and was eventually successful. O'Connor commanded VIII Corps in Normandy in 1944 and later during Operation Market Garden. In 1945 he was general officer in command, Eastern Command in India, and then headed the North West Army in the closing days of British rule in the subcontinent. He held the highest level of knighthood in four different orders of chivalry.



An American paratrooper demonstrates removal of an S-mine
The German S-mine (Schrapnellmine) is the best-known version of a class of mines known as bounding mines, which when triggered launch into the air to about waist height and then explode, propelling shrapnel horizontally at lethal speeds. The S-mine was an anti-personnel landmine developed by Nazi Germany in the 1930s and used extensively by German forces during World War II. It was designed to be used in open areas and to attack unshielded infantry. Two versions were produced, designated by the year of their first production: the SMi-35 and SMi-44. There are only minor differences between the two models (TM-E 30-451, 1945). The S-mine entered production in 1935 and served as a key part of the defensive strategy of the Third Reich. Until production ceased with the defeat of Germany in 1945, Germany produced over 1.93 million S-mines. These mines were responsible for inflicting heavy casualties and slowing, or even repelling, drives into German-held territory throughout the war. The design was lethal, successful and much imitated, and remains one of the definitive weapons of World War II.



British communication trench, Somme, 1916
Trench warfare is a form of war in which both opposing armies have static lines of fortifications dug into the ground, facing each other. Trench warfare arose when there was a revolution in firepower without similar advances in mobility and communications. Whilst periods of trench warfare occurred during the American Civil War and the Russo-Japanese War of 1904-1905, it reached a peak of brutality and bloodshed on the Western Front in the First World War.



Coin featuring Husein Gradaščević from 19th century
Husein Gradaščević was a Bosniak general who fought for Bosnian autonomy in the Ottoman Empire. Gradaščević was born in Gradačac in 1802 and grew up surrounded by a political climate of turmoil in the western reaches of the Ottoman Empire. After rising to the head of the Gradačac military captaincy, the young Husein developed a reputation for wise rule and tolerance and soon became one of the most popular figures in Bosnia. In 1831 Gradaščević was called upon to lead the movement for Bosnian autonomy. He overthrew the loyalist vizier and other anti-rebellion figures, becoming the de facto ruler of the Bosnian pashaluk in the process. By 1832 however, the tide of the rebellion had turned. Although the Bosniak uprising would not be completely quelled for another 18 years, Gradaščević was forced to flee to the Habsburg Monarchy on May 31. From there he negotiated for his return with the Sultan and was ultimately allowed back but barred from ever entering Bosnia again. He moved to Belgrade and then to Istanbul, where he died under mysterious circumstances. A legend in his own time, Gradaščević is considered a Bosniak national hero and one of the most revered figures in the history of Bosnia and Herzegovina.



The USS Arizona burning
On the morning of December 7, 1941, the Imperial Japanese Navy launched the Attack on Pearl Harbor. It was a surprise assault on the United States Navy base and Army air fields at Oahu, Hawaii Territory. The Japanese planes bombed all the U.S. military air bases on the island and the ships anchored at Pearl, including "Battleship Row". The next day, the U.S. Congress declared war on Japan with only Jeannette Rankin dissenting.



The Battle of Vigo Bay, October 12, 1702

The War of the Spanish Succession was a major European armed conflict that arose in 1701 after the death of the last Spanish Habsburg king, Charles II. The war proceeded for over a decade, and was marked by the military leadership of notable generals such as the Duc de Villars and the Duke of Berwick for France, the Duke of Marlborough for England, and Prince Eugene of Savoy for the Austrians. The war was concluded by the treaties of Utrecht (1713) and Rastatt (1714). As a result, Philip V remained King of Spain, but was removed from the French line of succession, thereby averting a union of France and Spain. The Austrians gained most of the Spanish territories in Italy and the Netherlands. As a result, France's hegemony over continental Europe was ended, and the idea of a balance of power became a part of the international order due to its mention in the Treaty of Utrecht.



The invasion plans for Operation Olympic
Operation Downfall was the overall Allied plan for the invasion of Japan at the end of World War II, but was ultimately never used. It was scheduled to occur in two parts — Operation Olympic, the invasion of Kyushu, set to begin in November, 1945; and later Operation Coronet, the invasion of Honshū near Tokyo, scheduled for the spring of 1946. Kyushu was to be invaded at three points — Miyazaki beach, Ariake beach, and Kushikino beach. Southern Kyushu would become a staging ground for operation Coronet, and would give the Allies a valuable airbase from which to operate. Following the atomic bombing of Hiroshima and Nagasaki, and the Soviet declaration of war against Japan, the Japanese surrendered and the operation was cancelled.



The Puerto Rican 65th Infantry Regiment's bayonet charge during the Korean War.

The military history of Puerto Rico dates back to the 16th century when Spanish conquistadors battled against the native Tainos and continues to the present-day. It was ruled by the Spanish Empire for four centuries, during which the Puerto Ricans defended the island against invasions from the British, French and Dutch. The island was seized by the United States during the Spanish-American War, and Spain officially ceded it under the terms of the 1898 Treaty of Paris which ended the War. Now a United States territory, as citizens of the United States, Puerto Ricans have participated in every major conflict in which the United States has been involved from World War I onward.



Hoplites in combat
The Corinthian War was an ancient Greek military conflict between Sparta and four allied states, Thebes, Athens, Corinth, and Argos, which were initially backed by Persia. The immediate cause of the war was a local conflict in northwest Greece in which both Thebes and Sparta intervened. The deeper cause, however, was hostility towards Sparta provoked by that city's unilateral domination of Greek politics in the nine years after the end of the Peloponnesian War. The war was fought on two fronts, on land near Corinth and Thebes and at sea in the Aegean. On land, the Spartans achieved several early successes in major battles, but were unable to capitalize on their advantage, and the fighting soon became stalemated. At sea, the Spartan fleet was decisively defeated by a Persian fleet early in the war, an event which effectively ended Sparta's attempts to become a naval power. Taking advantage of this fact, Athens launched several naval campaigns in the later years of the war, recapturing a number of islands that had been part of the original Athenian Empire during the 5th century BC. Alarmed by these Athenian successes, the Persians stopped backing the allies and began supporting Sparta. This defection forced the allies to seek peace. The Peace of Antalcidas, commonly known as the King's Peace, was signed in 387 BC, ending the war.



Karl Dönitz
Karl Dönitz was a naval leader in Nazi Germany during World War II. Despite never joining the Nazi Party, Dönitz attained the high rank of Grand Admiral and served as Commander in Chief of Submarines, and later Commander in Chief of the German War Navy. Under his command, the U-boat fleet fought the Battle of the Atlantic, attempting to starve the United Kingdom of vital supply shipments. He also briefly served as President of Germany following the death of Adolf Hitler. Following the war, Dönitz went on trial as a war criminal in the Nuremberg Trials, charged with conspiracy to commit crimes against peace and planning, initiating and waging wars of aggression. Dönitz produced an affidavit from Admiral Chester Nimitz who testified that the United States had used unrestricted warfare as a tactic in the Pacific and that American submarines did not rescue survivors in situations where their own safety was in question. Ultimately, the tribunal found Dönitz guilty of both charges. He served ten years in Spandau Prison, West Berlin. Later, numerous Allied officers sent letters to Dönitz expressing their dismay over the verdict of his trial.



Beatty's flagship Lion burning after being hit by a salvo
The Battle of Jutland was the largest naval battle of World War I, and the only full-scale clash of battleships in that war. It was fought on 31 May1 June 1916, in the North Sea near Jutland. The combatants were the Kaiserliche Marine's High Seas Fleet, commanded by Vice Admiral Reinhard Scheer, and the Royal Navy's Grand Fleet, commanded by Admiral Sir John Jellicoe. The Germans planned to lure Vice Admiral Sir David Beatty's battlecruiser squadrons into the path of the main German battle fleet and so destroy them. But the British had learned from signal intercepts that a major fleet operation was in prospect, and on 30 May Jellicoe sailed with the Grand Fleet to rendezvous with Beatty. On the afternoon of 31 May, Beatty and Hipper encountered each other, and in a running battle Hipper drew the British into the path of the High Seas Fleet. Fourteen British and eleven German ships were sunk with great loss of life. Both sides claimed victory. The British had lost more ships and many more sailors, but Scheer's plan of destroying Beatty's squadrons had failed. For the remainder of the war, the German High Seas Fleet stayed in port. and never again contested control of the seas. Instead, the German Navy turned its efforts and resources to unrestricted submarine warfare.



Blitzkrieg was an operational-level military doctrine which employed mobile forces attacking with speed and surprise to prevent an enemy from organising a coherent defence. Conceived in the years after World War I, it grew out of the earlier doctrine of "Fire and Infiltration". It was used by the German Wehrmacht in World War II. Operations early in the war—the invasions of Poland, France, and the Soviet Union—were highly effective, owing to surprise, enemy unpreparedness and superior German military doctrines. Methods of blitzkrieg operations centered on using manoeuvre rather than attrition to defeat an opponent. The blitzkrieg thus first and foremost required a concentration of armoured assets at a focal point, closely supported by mobile infantry, artillery and close air support assets. These tactics required the development of specialised support vehicles, new methods of communication, new tactics, and the presence of a decentralised command structure. Broadly speaking, blitzkrieg operations required the development of mechanised infantry, self-propelled artillery and engineering assets that could maintain the rate of advance of the tanks. In combat, blitzkrieg forced slower defending forces into defensive pockets that were encircled and then destroyed by following German infantry.



British infantry advancing near Ginchy
The Battle of the Somme was one of the largest battles of World War I, with more than one million casualties. The British and French forces attempted to break through the German lines along a 25 mile (40 km) front north and south of the River Somme in northern France. One purpose of the battle was to draw German forces away from the battle of Verdun; however, by its end the losses on the Somme had exceeded those at Verdun. The battle is best remembered for its first day, July 1, 1916, on which the British suffered 57,470 casualties, making it the bloodiest day in the history of the British Army. As horrific as the battle of the Somme is in British memory, it also had a staggering impact on the German army; one officer famously describing it as "the muddy grave of the German field army." By the end of the battle the British had learnt many lessons in modern warfare while the Germans had suffered irreparable losses.



The Missouri, following the 1980s refit
The USS Missouri is a United States Navy battleship, notable as both the last battleship to be built by the United States, and as the site of the Japanese surrender at the end of World War II. Launched on 29 January 1944, the ship was the fourth and last of the Iowa-class "fast battleship" designs, as well as the final battleship to be commissioned by the Navy. At her launching, the ship was christened by Mary Margaret Truman, daughter of Harry S. Truman, then a senator from Missouri. During World War II, the Missouri saw action at the Battle of Iwo Jima and the Battle of Okinawa, as well as participating in the shelling of the Japanese home islands of Hokkaido and Honshū. In the 1950s, Missouri saw action in the Korean War, after which she was decommissioned into the United States Navy reserve fleets. She was recommissioned in the 1980s, and refitted with modern armaments. Later, she participated in the Gulf War. Missouri was decommissioned a final time on March 31, 1992, having received a total of eight battle stars, and is presently a museum ship at Pearl Harbor.



Raising the Flag on Iwo Jima is an iconic photograph taken on February 23, 1945 by Joe Rosenthal. It depicts five United States Marines and a U.S. Navy corpsman raising the Flag of the United States atop Mount Suribachi during the Battle of Iwo Jima in World War II. The photograph was instantly popular, being reprinted in hundreds of publications. Later, it became the only photograph to win the Pulitzer Prize for Photography in the same year as its publication, and ultimately came to be regarded as one of the most significant and recognizable images in history, and possibly the most reproduced photograph of all time. Of the six men depicted in the picture, three (Franklin Sousley, Harlon Block, and Michael Strank) did not survive the battle; the three survivors (John Bradley, Rene Gagnon, and Ira Hayes) became suddenly famous. The photograph was later used by Felix de Weldon to sculpt the USMC War Memorial, located just outside Washington, D.C..



Israeli paratroops breaking through an Egyptian commando ambush
The Yom Kippur War was fought from October 6 (the day of Yom Kippur) to October 26, 1973, between Israel and a coalition of Egypt and Syria. The War began with a surprise joint attack by Egypt and Syria into the Sinai and Golan Heights, respectively, which had been captured by Israel six years earlier during the Six-Day War. The Egyptians and Syrians advanced during the first 24–48 hours, after which momentum began to swing in Israel's favor. By the second week of the war, the Syrians had been pushed entirely out of the Golan Heights. In the Sinai to the south, the Israelis had struck at the "hinge" between two invading Egyptian armies, crossed the Suez Canal (where the old cease-fire line had been), and cut off an entire Egyptian army just as a United Nations cease-fire came into effect. The war had far-reaching implications for many nations. The Arab world, which had been humiliated by the lopsided defeat of the Egyptian-Syrian-Jordanian alliance during the Six-Day War, felt psychologically vindicated by its string of victories early in the conflict. This vindication paved the way for the peace process that followed, as well as liberalizations such as Egypt's infitah policy. The Camp David Accords which came soon after led to normalized relations between Egypt and Israel—the first time any Arab country had recognized the Israeli state. Egypt, which had already been drifting away from the Soviet Union, then left the Soviet sphere of influence almost entirely.



Polish boy scouts fighting in the uprising
The Warsaw Uprising was an armed struggle during the Second World War by the Polish Home Army (Armia Krajowa) to liberate Warsaw from German occupation and Nazi rule. It started on August 1, 1944 as a part of a nationwide uprising, Operation Tempest. The Polish troops resisted the German-led forces until October 2. An estimated 85% of the city was destroyed during the urban guerrilla war and after the end of hostilities. The Uprising started at a crucial point in the war as the Soviet army was approaching Warsaw. Although the Soviet army was within a few hundred metres of the city from September 16 onward, the link between the uprising and the advancing army was never made. This failure and the reasons behind it have been a matter of controversy ever since.



Drawing of Swedish soldiers belonging to the "new" allotment system and wearing uniforms of the 1830s.
The Swedish allotment system was a system used in Sweden for keeping a trained army at all times. The oldest variant of the system came into use in around 1640, and in 1682 an updated system was introduced. Both systems relied on estates and farms that provided housing, salary and some military equipment for a soldier or horseman. In exchange, all other men in households providing soldiers escaped conscription, and households providing a horseman gained a large tax reduction. The system provided a well-trained, fast-mobilized and relatively cheap army that had large success on the battlefields of Europe during the 17th century, but the system also took its toll on the population. The allotment system was not replaced until the early 1900s, when the Swedish Armed Forces started using a conscription system.



Napoleon Bonaparte
The military history of France represents a massive panorama of conflicts and struggles extending for more than 2,000 years over areas encompassing modern France, Europe, and European territorial possessions overseas. Gallo-Roman conflict predominated from 400 BCE to 50 BCE, with the Romans emerging victorious in the conquest of Gaul by Julius Caesar. After the decline of the Roman Empire, a Germanic tribe known as the Franks took control of Gaul by defeating competing tribes. In the eighteenth century, global competition with Great Britain led to defeat in the French and Indian War, where France lost its North American holdings and India, but consolation came in the form of the American Revolutionary War, where massive French aid led to America's independence. Internal political upheaval eventually led to 23 years of nearly continuous war in the French Revolutionary Wars and the Napoleonic Wars. France reached the zenith of its power during this period, but by 1815 it had been restored to its pre-Revolutionary borders. Following defeat in the Franco-Prussian War, Franco-German rivalry reasserted itself again in World War I, this time France emerging as the winner. Tensions over the Versailles Treaty led to the Second World War, where it was humiliated in the Battle of France. The Allies eventually emerged victorious over the Germans, however, and France was given an occupation zone in Germany. Today, French military intervention is most often seen in its former colonies and with its NATO allies in hot spots around the world.



Ensign of the Imperial Japanese Navy
The Imperial Japanese Navy was the navy of Japan from 1869 until 1947, when it was dissolved following Japan's renouncement of the use of force as a means of settling international disputes in its post-World War II Constitution of Japan. The origins of the Imperial Japanese Navy trace back to early interactions with states on the Asian continent at the beginning of the medieval period, and reached a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery. After two centuries of stagnation during the country's ensuing seclusion policy under the shoguns of the Edo period, Japan's navy was comparatively backward when the country was forced open to trade by American intervention in 1854. This eventually led to the Meiji Restoration, a period of frantic modernization and industrialization accompanied by the re-ascendance of the emperor. The navy's history of successes, sometimes against much more powerful foes as in the 1895 Sino-Japanese war and the 1905 Russo-Japanese War, ended with almost complete annihilation in 1945 against the United States Navy, and official dissolution at the end of the conflict.



An Iranian depiction of the Muslim pursuit following the battle
The Battle of Badr was a key battle in the early days of Islam and a turning point in Muhammad's war against his Quraish opponents in Mecca. The battle has been passed down in Islamic history as a decisive victory ascribed to either divine intervention or the genius of Muhammad. Although it is one of the few battles mentioned by name in the Muslim holy book, the Qur'an, virtually all contemporary knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, written down decades after the battle. Prior to the battle, the Muslims and Meccans had fought several smaller skirmishes in late 623 and early 624, as the Muslim ghazawāt plundering raids grew increasingly commonplace, but this was their first large-scale battle. Muhammad was leading a raiding party against a caravan when he was surprised by a much larger Quraishi army. Advancing to a strong defensive position, Muhammad's well-disciplined men managed to shatter the Meccan lines, killing several important leaders including Muhammad's chief opponent, Amr ibn Hishām. For the early Muslims, the battle was extremely significant because it was the first sign that they might eventually overcome their enemies in Mecca, one of the richest and most powerful pagan cities in pre-Islamic Arabia.



Cross section of the Jarmann M1884
The Norwegian Jarmann M1884 was a bolt action repeating rifle fireing a 10.15 mm black powder cartridge in an 8-round, tubular magazine. It was among the earliest repeating rifles to be adopted in the world. Its adoption, and subsequent modifications, turned the Norwegian Army from a fighting force armed with single-shot black powder weapons into a force armed with modern repeating weapons firing smokeless ammunition. Several thousands were manufactured to equip both Norwegian and Swedish forces in the 1880s. The design is unique, and is the brainchild of Norwegian engineer Jacob Smith Jarmann. After the design had been phased out of the Norwegian Army, a number of the weapons were rebuilt as harpoon guns.



Polish defenses near Milosna
The Polish-Soviet War was the war that determined the borders between two nascent states in post-World War I Europe. This armed struggle was a result of conflicting attempts — by Poland, whose statehood had just been re-established after her being partitioned in the late 18th century, to secure territories which she had lost in partitions or earlier — and by Soviets who aimed to take control of the same territories that had since then been part of Imperial Russia until their occupation by Germany during World War I. Both states claimed victory in the war: the Poles claimed a successful defense of their state, while the Soviets claimed a repulse of the Polish Kiev offensive, which was sometimes viewed as part of foreign interventions in the Russian Civil War.



Closeup of a Krag-Jørgensen receiver

The Krag-Jørgensen is a repeating bolt action rifle designed by the Norwegians Ole Herman Johannes Krag and Erik Jørgensen in the late 19th century. It was adopted as a standard arm by Denmark, the United States and Norway. The most distinctive feature of the Krag-Jørgensen action was its magazine. While other rifles of its era used a box magazine, the magazine of the Krag-Jørgensen was integral with the receiver, featuring an opening on the right hand side with a hinged cover. The cartridges were inserted through the side opening, and were pushed up, around, and into the action by a spring follower. This presented both advantages and disadvantages compared with the standard top-loading "box" magazine; among other things, using a "stripper clip" to reload was impossible. At the same time, unlike a top-loading magazine, the Krag-Jørgensen's magazine could be topped up without opening the rifle's bolt. Today, the Krag-Jørgensen is a popular collector's rifle, and is valued by shooters for its smooth action.



The nuclear bombing of Nagasaki
A nuclear weapon is a weapon that derives its energy from nuclear reactions and has enormous destructive power. Countries declared nuclear powers are the United States, Russia, United Kingdom, France, and the People's Republic of China. India and Pakistan have also publicly tested nuclear weapons. Israel is also widely believed to possess nuclear weapons. Such weapons have been used only twice in combat, by the United States against the Japanese cities of Hiroshima and Nagasaki at the conclusion of World War II.



Soviet sappers erecting a bridge across northern Dnieper
The Second Battle of Smolensk was a major World War II Red Army offensive in western Russia, staged almost simultaneously with the Battle of the Lower Dnieper. The two-month offensive led by Generals Andrei Yeremenko and Vasily Sokolovsky was aimed at clearing the German presence from the Smolensk and Bryansk regions. Smolensk had been under German occupation since the first Battle of Smolensk in 1941. Despite an impressive German defense setup, the Red Army was able to stage several breakthroughs, liberating several major cities, including Smolensk and Roslavl, and moving into occupied Belorussia. Although playing a major military role in its own right, the Smolensk Operation was also important for its effect on the Battle of Dnieper. It has been estimated that as many as 55 German divisions were committed to counter the Smolensk Operation—divisions that were critically needed to prevent Soviet troops from crossing the Dnieper River in the south. Additionally, the operation allowed the Red Army to repulse German forces definitively from the Smolensk landbridge, historically the most important approach for an attack on Moscow from the west.



The breech end of two Kammerlader rifles
The Kammerlader was the first Norwegian breech loading rifle, and among the very first breech loaders adopted for use by an armed force anywhere in the world. A single shot, black powder rifle, the kammerlader was operated with a crank mounted on the side of the receiver. This made it much quicker and easier to load than the weapons previously used. Kammerladers quickly gained a reputation for being fast and accurate rifles, and would have been a deadly weapon against massed ranks of infantry. The kammerladers were phased out as more modern rifles were approved for use. They were either modified for rimfire cartridges, sold off to civilians or melted for scrap. Rifles sold to civilians were often modified for use as shotguns or hunting weapons. Today it is hard to find an unmodified kammerlader, and collectors often pay high prices for them.



Witold Pilecki, in Auschwitz
Witold Pilecki was a soldier of the Second Polish Republic, founder of the resistance movement Secret Polish Army (Tajna Armia Polska) and member of the Home Army (Armia Krajowa). During World War II he was the only person to volunteer to be imprisoned at Auschwitz Concentration Camp. While there, he organized inmate resistance and as early as 1940 informed the Western Allies of Nazi Germany's camp atrocities. He escaped from Auschwitz in 1943 and took part in the Warsaw Uprising (August-October 1944). Pilecki was executed in 1948 by communist authorities.



Chinese representatives inspecting a Junkers aircraft, 1933
During the period from 1911 to 1941, Sino-German cooperation was often close, culminating in an alliance between the Republic of China and Germany. Close cooperation dating back to the 1920s was instrumental in modernizing the industry and the armed forces of the Republic of China, especially in the period immediately preceding the Second Sino-Japanese War. Succeeding the Qing Dynasty in 1912, the Republic of China was fraught with factional warlordism from the inside and foreign incursions from the outside. The Northern Expedition of 1928 nominally unified China for the first time under Kuomintang control, yet Imperial Japan emerged as the greatest foreign threat. The urgent need for China to modernize its military and national defense industry, coupled with Germany's need for a stable supply of raw materials, put the two countries on the road of close relations from the late 1920s to the late 1930s. Although the period of intense cooperation was relatively short, lasting only from the Nazi takeover of Germany in 1933 to the start of the war with Japan in 1937, it had a profound effect on the modernization efforts of China, as well as her capability to resist the Japanese in the war.



The north face of the Shrine
The Shrine of Remembrance, located in St Kilda Road, Melbourne, is one of the largest war memorials in Australia. It was built as a memorial to the 114,000 men and women of Victoria who served in World War I, but soon came to be seen as Australia's major memorial to all the 60,000 Australians who died in that war. It now serves as a memorial for all Australians who served in war, and is the site of annual observances of ANZAC Day (25 April) and Remembrance Day (11 November). Around the Sanctuary walls is a frieze of 12 carved panels depicting the armed services at work and in action during World War I. The Sanctuary is surrounded by a narrow walkway called the Ambulatory. Along the Ambulatory are 42 bronze caskets containing hand-written, illuminated Books of Remembrance with the names of every Victorian who enlisted for active service with the Australian Imperial Force (AIF) or Australian Naval and Military Expeditionary Force in World War I or died in camp prior to embarkation.



Conrad III of Germany personally led the crusade
The Second Crusade was the second major crusade launched from Europe, called in 1145 in response to the fall of the County of Edessa the previous year. Edessa was the first of the Crusader states to have been founded during the First Crusade, and was the first to fall. The Second Crusade was announced by Pope Eugenius III, and was the first of the crusades to be led by European kings, namely Louis VII of France and Conrad III of Germany. The armies of the two kings marched separately across Europe and were separately defeated by the Seljuk Turks. Louis and Conrad and the remnants of their armies reached Jerusalem and in 1148 participated in an ill-advised attack on Damascus. The crusade in the east was a failure for the crusaders and a great victory for the Muslims. It would ultimately lead to the fall of Jerusalem and the Third Crusade at the end of the 12th century. The only success came on the opposite end of the Mediterranean, where English crusaders, on the way by ship to the Holy Land, fortuitously stopped and helped capture Lisbon in 1147.



Stanislaw Koniecpolski

Stanislaw Koniecpolski was a Polish nobleman (szlachcic), magnate, official (starost and castellan) and hetman - second highest military commander of the Polish-Lithuanian Commonwealth. Koniecpolski lived a life that involved almost constant warfare and during his military career he won many victories. Before he reached the age of 20, he had fought in the Dimitriads and the Moldavian Magnate Wars, where he was taken captive by the forces of Ottoman Empire at the Battle of Cecora in 1620. When released in 1623 he soon defeated Ottoman vassals the Tatars in 1624. With inferior forces he fought Swedish forces of Gustav Adolphus to a stalemate in Prussia during the second phase of the Polish-Swedish War (1626-1629). He defeated a major Turkish invasion at Kamieniec Podolski in Ukraine in 1634 and during his life led many other successful campaigns against the rebellious Cossacks and invading Tatars. He is considered to be one of the most skilled and famous military commanders in the history of Poland and Lithuania.



USS Wisconsin at sea, circa 1990
USS Wisconsin is an Iowa-class battleship, and is the second ship of the United States Navy named in honor of the U.S. state of Wisconsin. She was built at the Philadelphia Navy Yard, and launched on December 7, 1943. During her career Wisconsin served in World War II, where she shelled Japanese fortifications at Ulithi and Leyte Gulf, and screened U.S. aircraft carriers as they conducted air raids against enemy positions. During the Korean War she shelled North Korean targets in support of UN and South Korean ground operations, after which she was decommissioned into the United States Navy reserve fleets, better known as the mothball fleet. She was reactivated and modernized in 1986 as part of the "600-ship Navy" plan, and participated in the 1991 Gulf War. Wisconsin was last decommissioned in September 1991 and currently functions as a museum ship at the Nauticus National Maritime Center in Norfolk, Virginia. Wisconsin was struck from the Naval Vessel Register in 2006 and is currently awaiting donation for use as a museum ship.



Joan of Arc, c. 1485
Joan of Arc is a national heroine of France and a saint of the Roman Catholic Church. She had visions, believed to be from God, which led to the liberation of her homeland from English dominance in the Hundred Years' War. The then-uncrowned King Charles VII sent her to the siege of Orléans as part of a relief mission. She gained prominence when she overcame the disregard of veteran commanders and ended the siege in only nine days. Several more swift victories led to Charles VII's coronation at Rheims and settled the disputed succession to the throne. The renewed French confidence outlasted Joan of Arc's own brief career. She refused to leave the field when she was wounded during an attempt to recapture Paris that fall. Hampered by court intrigues, she led only minor companies from then on, and fell prisoner during a skirmish near Compiègne the following spring. A politically-motivated trial convicted her of heresy. The English regent, John, Duke of Bedford, had her burnt at the stake in Rouen. Pope Callixtus III reopened Joan's case; a new finding overturned the original conviction. Her piety to the end impressed the retrial court. Pope Benedict XV canonized her on 16 May 1920.



Attalus I ruled Pergamon, a Greek city-state in present-day Turkey, from 241 BCE to 197 BCE. He was the second cousin and the adoptive son of Eumenes I, whom he succeeded, and was the first of the Attalid dynasty to assume the title of king. He won an important victory over the Galatians, newly arrived Celtic tribes from Thrace, who had been, for more than a generation, plundering and exacting tribute throughout most of Asia Minor without any serious check. This victory, celebrated by the triumphal monument at Pergamon, famous for its Dying Gaul, and the liberation from the Gallic "terror" which it represented, earned for Attalus the name of "Soter," and the title of "king." A courageous and capable general and loyal ally of Rome, he played a significant role in the first and second Macedonian Wars, waged against Philip V of Macedon. He conducted numerous naval operations, harassing Macedonian interests throughout the Aegean, winning honors, collecting spoils, and gaining for Pergamon possession of the Greek islands of Aegina during the first war, and Andros during the second, twice narrowly escaping capture at the hands of Philip. He died in 197 BCE, shortly before the end of the second war, at the age of 72, having suffered an apparent stroke while addressing a Boeotian war council some months before.



Thrasybulus receiving an olive crown for his campaign against the Thirty Tyrants
Thrasybulus was an Athenian general and democratic leader. In 411 BC, in the wake of an oligarchic coup at Athens, the pro-democracy sailors at Samos elected him as a general, making him a primary leader of the successful democratic resistance to that coup. As general, he was responsible for recalling the controversial nobleman Alcibiades from exile, and the two worked together extensively over the next several years. In 411 and 410, Thrasybulus commanded several critical Athenian naval victories, along with Alcibiades and others. After Athens' defeat in the Peloponnesian War, Thrasybulus led the democratic resistance to the new oligarchic government, known as the Thirty Tyrants, that the victorious Spartans imposed on Athens. In 404 BC, he commanded a small force of exiles that invaded Attica and, in successive battles, defeated first a Spartan garrison and then the forces of the oligarchics. In the wake of these victories, democracy was reestablished in Athens. As a leader of this revived democracy in the 4th century BC, Thrasybulus advocated a policy of resistance to Sparta and sought to restore Athens' imperial power. He was killed in 388 BC while leading an Athenian naval force in the Corinthian War.



Epaminondas
Epaminondas was a Theban general and statesman who transformed Thebes, leading it out of Spartan subjugation into a preeminent position in Greek geopolitics. In the process he broke Spartan military power with his victory at Leuctra and liberated the Messenian helotsPeloponnesian Greeks who had been enslaved under Spartan rule for some 200 years. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was militarily influential as well; he invented several major battlefield tactics. Cicero once called him "the first man of Greece", but Epaminondas has fallen into relative obscurity in modern times. The changes he wrought on the Greek political order did not long outlive him, as the cycle of shifting hegemonies and alliances continued unabated. Just 27 years after his death, a recalcitrant Thebes was obliterated by Alexander the Great. Thus Epaminondas—who had been praised in his time as an idealist and liberator—is today largely remembered for a decade (371 to 362 BC) of campaigning that sapped the strength of the great land powers of Greece and paved the way for the Macedonian conquest.



Władysław Sikorski during World War II
Władysław Sikorski was a Polish military and political leader. Before World War I, he became a founder and member of several underground organizations that promoted the cause of Polish independence. He fought with distinction during the Polish-Soviet War, in which he played a prominent role in the decisive Battle of Warsaw. During World War II he became Prime Minister of the Polish Government in Exile, Commander-in-Chief of the Polish Armed Forces, and a staunch advocate of the Polish cause on the diplomatic scene. He supported the reestablishment of diplomatic relations between Poland and the Soviet Union, which had been severed after the Soviet alliance with Germany in the 1939 invasion of Poland. In April 1943, however, Soviet dictator Joseph Stalin broke off Soviet-Polish diplomatic relations following Sikorski's request that the International Red Cross investigate the Katyn Massacre. In July 1943, Sikorski was killed in a plane crash into the sea immediately on takeoff from Gibraltar. The exact circumstances of his death remain in dispute, which has given rise to ongoing conspiracy theories.



A stained glass window showing the death of Penda of Mercia
Penda was a 7th-century King of Mercia, a kingdom in what is today the English Midlands. A pagan at a time when Christianity was taking hold in many of the Anglo-Saxon kingdoms, Penda participated in the defeat of the powerful Northumbrian king Edwin at the Battle of Hatfield Chase in 633; nine years later, he defeated and killed Edwin's eventual successor, Oswald, at the Battle of Maserfield. From this point he was probably the most powerful of the Anglo-Saxon rulers of the time; he defeated the East Angles, drove the king of Wessex into exile for three years, and continued to wage war against the Bernicians of Northumbria. Thirteen years after Maserfield, he suffered a crushing defeat at the Battle of the Winwaed in the course of a final campaign against the Bernicians and was killed.
