The Battle of the Bulge (16 December 1944 – 25 January 1945) was a major German offensive campaign launched through the densely forested Ardennes region of Wallonia in Belgium, France, and Luxembourg on the Western Front toward the end of World War II in Europe. Hitler planned the offensive with the primary goal to recapture the important harbour of Antwerp. The surprise attack caught the Allied forces completely off guard. United States forces bore the brunt of the attack and incurred the highest casualties for any operation during the war. The battle also severely depleted Germany's armored (tanks and tracked vehicles) reserves on the western front. German personnel and Luftwaffe aircraft also sustained heavy losses.

The battle was known by different names. The Germans referred to it as Unternehmen Wacht am Rhein ("Operation Watch on the Rhine"), while the French named it the Bataille des Ardennes ("Battle of the Ardennes"). The Allies called it the Ardennes Counteroffensive. The phrase "Battle of the Bulge" was coined by contemporary press to describe the way the Allied front line bulged inward on wartime news maps and became the best known name for the battle.

About 610,000 American forces were involved in the battle, and 89,000 were injured, including 19,000 killed. It was the largest and bloodiest battle fought by the United States in World War II.

The Battle of Stalingrad (August 1942 – 2 February 1943) was a major battle of World War II in which Nazi Germany and its allies fought the Soviet Union for control of the city of Stalingrad (now Volgograd) in the south-western Soviet Union. Marked by constant close quarters combat and direct assaults on civilians by air raids, it is the single largest and bloodiest battle in the history of warfare. The heavy losses inflicted on the Wehrmacht make it arguably the most strategically decisive battle of the whole war. It was a turning point in the European theatre of World War II–the German forces never regained the initiative in the East and withdrew a vast military force from the West to replace their losses.

The German offensive to capture Stalingrad began in late summer 1942 using the 6th Army and elements of the 4th Panzer Army. The attack was supported by intensive Luftwaffe bombing that reduced much of the city to rubble. The fighting degenerated into building-to-building fighting, and both sides poured reinforcements into the city. By mid-November 1942, the Germans had pushed the Soviet defenders back at great cost into narrow zones generally along the west bank of the Volga River.

On 19 November 1942, the Red Army launched Operation Uranus, a two-pronged attack targeting the weaker Romanian and Hungarian forces protecting the German 6th Army's flanks. The Axis forces on the flanks were overrun and the 6th Army was cut off and surrounded in the Stalingrad area. Adolf Hitler ordered that the army stay in Stalingrad and make no attempt to break out; instead, attempts were made to supply the army by air and to break the encirclement from the outside. Heavy fighting continued for another two months. By the beginning of February 1943, the Axis forces in Stalingrad had exhausted their ammunition and food. The remaining elements of the 6th Army surrendered. The battle lasted five months, one week, and three days.

The Yalta Conference, sometimes called the Crimea Conference and codenamed the Argonaut Conference, held February 4–11, 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union, represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill and Premier Joseph Stalin, respectively, for the purpose of discussing Europe's post-war reorganization. The conference convened in the Livadia Palace near Yalta in Crimea.

The meeting was intended mainly to discuss the re-establishment of the nations of war-torn Europe. Within a few years, with the Cold War dividing the continent, Yalta became a subject of intense controversy. To some extent, it has remained controversial.

Yalta was the second of three wartime conferences among the Big Three. It had been preceded by the Tehran Conference in 1943, and was followed by the Potsdam Conference in July 1945, which was attended by Stalin, Churchill (who was replaced midpoint by the newly elected British Prime Minister Clement Attlee) and Harry S. Truman, Roosevelt's successor.

Anzac Day is a national day of remembrance in Australia and New Zealand that broadly commemorates all Australians and New Zealanders "who served and died in all wars, conflicts, and peacekeeping operations" and "the contribution and suffering of all those who have served." Observed on 25 April each year, Anzac Day was originally to honour the members of the Australian and New Zealand Army Corps (ANZAC) who fought at Gallipoli in the Ottoman Empire during World War I. Anzac Day is also observed in the Cook Islands, Niue, Pitcairn Islands, and Tonga, and previously also as a national holiday in Papua New Guinea and Samoa.

With the coming of the Second World War, Anzac Day became a day on which to commemorate the lives of Australians and New Zealanders lost in that war as well and in subsequent years. The meaning of the day has been further broadened to include those killed in all the military operations in which the countries have been involved.

Victory in Europe Day, generally known as V-E Day, VE Day, or simply V Day was the public holiday celebrated on 8 May 1945 (7 May in Commonwealth realms) to mark the formal acceptance by the Allies of World War II of Nazi Germany's unconditional surrender of its armed forces. It thus marked the end of World War II in Europe.

As the Soviet representative in Reims had no authority to sign the German instrument of surrender, the Soviet leadership proposed to consider Reims surrender as a "preliminary" act. The surrender ceremony was repeated in Berlin on May 8, where the instrument of surrender was signed by supreme German military commander Wilhelm Keitel, by Georgy Zhukov and Allied representatives. Since the Soviet Union was to the east of Germany, it was 9 May Moscow Time when the German military surrender became effective, which is why Russia and most of the former Soviet republics commemorate Victory Day on 9 May instead of 8 May.

Memorial Day is a federal holiday in the United States for remembering the men and women who died while serving in the country's armed forces. The holiday, which is celebrated every year on the last Monday of May, was formerly known as Decoration Day and originated after the American Civil War to commemorate the Union and Confederate soldiers who died in the war. By the 20th century, Memorial Day had been extended to honor all Americans who died while in the military service.

The Battle of Midway in the Pacific Theater of Operations was one of the most important naval battles of World War II. Between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor, and one month after the Battle of the Coral Sea, the United States Navy (USN), under Admirals Chester W. Nimitz, Frank Jack Fletcher, and Raymond A. Spruance decisively defeated an attack by the Imperial Japanese Navy (IJN), under Admirals Isoroku Yamamoto, Chuichi Nagumo, and Nobutake Kondo on Midway Atoll, inflicting irreparable damage on the Japanese fleet. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare." It was Japan's first naval defeat since the Battle of Shimonoseki Straits in 1863.

The Japanese operation, like the earlier attack on Pearl Harbor, sought to eliminate the United States as a strategic power in the Pacific, thereby giving Japan a free hand in establishing its Greater East Asia Co-Prosperity Sphere. The Japanese hoped that another demoralizing defeat would force the U.S. to capitulate in the Pacific War and thus ensure Japanese dominance in the Pacific.

The Japanese plan was to lure the United States' aircraft carriers into a trap. The Japanese also intended to occupy Midway as part of an overall plan to extend their defensive perimeter in response to the Doolittle air raid on Tokyo. This operation was also considered preparatory for further attacks against Fiji, Samoa, and Hawaii itself.

The plan was handicapped by faulty Japanese assumptions of the American reaction and poor initial dispositions. Most significantly, American codebreakers were able to determine the date and location of the attack, enabling the forewarned U.S. Navy to set up an ambush of its own. Four Japanese aircraft carriers—Akagi, Kaga, Soryu and Hiryu, all part of the six-carrier force that had attacked Pearl Harbor six months earlier—and a heavy cruiser were sunk at a cost of one American aircraft carrier and a destroyer. After Midway and the exhausting attrition of the Solomon Islands campaign, Japan's shipbuilding and pilot training programs were unable to keep pace in replacing their losses, while the U.S. steadily increased its output in both areas.

In the military, D-Day is the day on which a combat attack or operation is to be initiated. The best known D-Day is June 6, 1944—the day of the Normandy landings—initiating the Western Allied effort to liberate mainland Europe from Nazi occupation during World War II. However, many other invasions and operations had a designated D-Day, both before and after that operation.

France, crushed, surrenders to Germany and signs an armistice. Great Britain now stands alone against the Axis powers.

The Potsdam Conference was held at Cecilienhof, the home of Crown Prince Wilhelm Hohenzollern, in Potsdam, occupied Germany, from 17 July to 2 August 1945. (In some older documents it is also referred to as the Berlin Conference of the Three Heads of Government of the USSR, USA and UK) Participants were the Soviet Union, the United Kingdom and the United States. The three powers were represented by Communist Party General Secretary Joseph Stalin, Prime Ministers Winston Churchill, and, later, Clement Attlee, and President Harry S. Truman.

Stalin, Churchill, and Truman—as well as Attlee, who participated alongside Churchill while awaiting the outcome of the 1945 general election, and then replaced Churchill as Prime Minister after the Labour Party's defeat of the Conservatives—gathered to decide how to administer punishment to the defeated Nazi Germany, which had agreed to unconditional surrender nine weeks earlier, on 8 May (V-E Day).

The goals of the conference also included the establishment of post-war order, peace treaty issues, and countering the effects of the war.

Operation Anvil Dragoon was the Allied invasion of southern France on 15 August 1944, during World War II. The invasion was initiated via a parachute drop by the 1st Airborne Task Force, followed by an amphibious assault by elements of the U.S. Seventh Army, followed a day later by a force made up primarily of the French First Army. The landing caused the German Army Group G to abandon southern France and to retreat under constant Allied attacks to the Vosges Mountains. Despite being a large and complex military operation with a well-executed amphibious and airborne component, Operation Dragoon is not well known; it came in the later stages of the war and was overshadowed by the earlier and larger Operation Overlord that invaded Normandy.

August 15 is the official V-J Day for the UK, while the official U.S. commemoration is September 2. The name, V-J Day, had been selected by the Allies after they named V-E Day for the victory in Europe. On September 2, 1945, a formal surrender ceremony was performed in Tokyo Bay, Japan, aboard the battleship USS Missouri.

In Japan, August 15 usually is known as the “memorial day for the end of the war” (終戦記念日 Shūsen-kinenbi?); the official name for the day, however, is "the day for mourning of war dead and praying for peace" (戦没者を追悼し平和を祈念する日 Senbotsusha o tsuitōshi heiwa o kinensuru hi?). This official name was adopted in 1982 by an ordinance issued by the Japanese government.

August 15 is commemorated as Liberation Day in Korea.

Victory over Japan Day (also known as Victory in the Pacific Day, V-J Day, or V-P Day) is a name chosen for the day on which Japan surrendered, in effect ending World War II, and subsequent anniversaries of that event. The term has been applied to both of the days on which the initial announcement of Japan’s surrender was made – to the afternoon of August 15, 1945, in Japan, and, because of time zone differences, to August 14, 1945 (when it was announced in the United States and the rest of the Americas and Eastern Pacific Islands) – as well as to September 2, 1945, when the signing of the surrender document occurred, officially ending World War II.

Britain and France declare war on Germany honoring their commitment to Poland. President Franklin D. Roosevelt invokes the Neutrality Act but notes, "Even a neutral cannot be asked to close his mind or his conscience."

The Second Battle of El Alamein (23 October – 11 November 1942) took place near the Egyptian coastal city of El Alamein. With the Allies victorious, it marked a major turning point in the Western Desert Campaign of the Second World War. It followed the First Battle of El Alamein, which had stalled the Axis advance into Egypt, after which, in August 1942, Lieutenant-General Bernard Montgomery had taken command of the British Eighth Army from General Claude Auchinleck. This victory turned the tide in the North African Campaignand ended the Axis threat to Egypt, the Suez Canal, and of gaining access to the Middle Eastern and Persian oil fields via North Africa. From a psychological perspective, Second El Alamein revived the morale of the Allies, being the first major offensive against the Axis since the start of the European war in 1939 in which the Western Allies had achieved a decisive victory.

The battle coincided with the Allied invasion of French North Africa in Operation Torch, which started 8 November. The operation is also considered to be the end of the 200 days of dread of the Yishuv in the British Mandate of Palestine.

Operation Torch (initially called operation Gymnast) was the British-American invasion of French North Africa during the North African Campaign of the Second World War which started on 8 November 1942.

The Soviet Union had pressed the United States and United Kingdom to start operations in Europe and open a second front to reduce the pressure of German forces on the Soviet troops. While the American commanders favored Operation Sledgehammer, landing in Occupied Europe as soon as possible, the British commanders believed that such a course would end in disaster.

An attack on French North Africa was proposed instead, which would clear the Axis powers from North Africa, improve naval control of the Mediterranean Sea, and prepare for an invasion of Southern Europe in 1943. American President Franklin D. Roosevelt suspected the African operation would rule out an invasion of Europe in 1943 but agreed to support British Prime Minister Winston Churchill.

Veterans Day is an official United States holiday that honors people who have served in the U.S. Armed Forces, also known as veterans. It is a federal holiday that is observed on November 11. It coincides with other holidays such as Armistice Day and Remembrance Day, which are celebrated in other parts of the world and also mark the anniversary of the end of World War I (major hostilities of World War I were formally ended at the 11th hour of the 11th day of the 11th month of 1918, when the Armistice with Germany went into effect).

Remembrance Day (also known as Poppy Day) is a memorial day observed in Commonwealth of Nations member states since the end of the First World War to remember the members of their armed forces who have died in the line of duty.
