WW2 Timeline

  • Japanese Invasion of China

    China fought Japan, with some economic help from Germany, the Soviet Union and the United States. After the Japanese attack on Pearl Harbor in 1941, the war would merge into the greater conflict of World War II as a major front of what is broadly known as the Pacific War. The Second Sino-Japanese War was the largest Asian war in the 20th century.
  • Germany's invasion of Poland

    The Invasion of Poland, also known as the September Campaign, or the 1939 Defensive War in Poland during the Poland Campaign.
  • German Blitzkrieg

    A German term for “lightning war,” blitzkrieg is a military tactic designed to create disorganization among enemy forces through the use of mobile forces and locally concentrated firepower. Its successful execution results in short military campaigns, which preserves human lives and limits the expenditure of artillery.
  • Operation Barbarossa

    The invasion covered a front from the North Cape to the Black Sea, a distance of two thousand miles. By this point German combat effectiveness had reached its apogee; in training, doctrine, and fighting ability, the forces invading Russia represented the finest army to fight in the twentieth century.
  • Pearl Harbor

    Just before 8 a.m. on December 7, 1941, hundreds of Japanese fighter planes attacked the American naval base at Pearl Harbor near Honolulu, Hawaii. The barrage lasted just two hours, but it was devastating: The Japanese managed to destroy nearly 20 American naval vessels, including eight enormous battleships, and more than 300 airplanes. More than 2,000 Americans soldiers and sailors died in the attack, and another 1,000 were wounded.
  • Wannsee Conference

    The Wannsee Conference was a meeting of senior officials of Nazi Germany, held in the Berlin suburb of Wannsee on 20 January 1942.

  • Battle of Midway

    Six months after the attack on Pearl Harbor, the United States defeated Japan in one of the most decisive naval battles of World War II. Thanks in part to major advances in code breaking, the United States was able to preempt and counter Japan’s planned ambush of its few remaining aircraft carriers, inflicting permanent damage on the Japanese Navy.
  • Battle of Stalingrad

    The Battle of Stalingrad, was the successful Soviet defense of the city of Stalingrad in the U.S.S.R. during World War II. Russians consider it to be the greatest battle of their Great Patriotic War, and most historians consider it to be the greatest battle of the entire conflict. It stopped the German advance into the Soviet Union and marked the turning of the tide of war in favor of the Allies.
  • Warsaw Ghetto uprising

    From April 19 to May 16, 1943, residents of the Jewish ghetto in Nazi-occupied Warsaw, Poland, staged an armed revolt against deportations to extermination camps. The Warsaw ghetto uprising inspired other revolts in extermination camps and ghettos throughout German-occupied Eastern Europe.
  • Operation Gomorrah

    Britain had suffered the deaths of 167 civilians as a result of German bombing raids in July. Now the tables were going to turn. The evening of July 24 saw British aircraft drop 2,300 tons of incendiary bombs on Hamburg in just a few hours. The explosive power was the equivalent of what German bombers had dropped on London in their five most destructive raids. More than 1,500 German civilians were killed in that first British raid.

  • -D-Day (Normandy Invasion

    The Western Allies of World War II launched the largest amphibious invasion in history when they assaulted Normandy, located on the northern coast of France, on 6 June 1944. The invaders were able to establish a beachhead as part of Operation Overlord after a successful "D-Day," the first day of the invasion.
  • Operation Thunderclap

    Operation Thunderclap was the code for a cancelled operation planned in August 1944 but shelved and never implemented. The plan envisaged a massive attack on Berlin in the belief that would cause 220,000 casualties with 110,000 killed, many of them key German personnel, which would shatter German morale. However, it was later decided that the plan was unlikely to work.
  • Battle of Iwo Jima

    The American amphibious invasion of Iwo Jima during World War II stemmed from the need for a base near the Japanese coast. Following elaborate preparatory air and naval bombardment, three U.S. marine divisions landed on the island in February 1945. Iwo Jima was defended by roughly 23,000 Japanese army and navy troops, who fought from an elaborate network of caves, dugouts, tunnels and underground installations.
  • Battle of Okinawa

    Last and biggest of the Pacific island battles of World War II, the Okinawa campaign involved the 287,000 troops of the U.S. Tenth Army against 130,000 soldiers of the Japanese Thirty-second Army. At stake were air bases vital to the projected invasion of Japan. By the end of the 82-day campaign, Japan had lost more than 77,000 soldiers and the Allies had suffered more than 65,000 casualties—including 14,000 dead.
  • VE Day

    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 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.
  • Dropping of the atomic bombs

    The United States becomes the first and only nation to use atomic weaponry during wartime when it drops an atomic bomb on the Japanese city of Hiroshima. Though the dropping of the atomic bomb on Japan marked the end of World War II, many historians argue that it also ignited the Cold War.
  • VJ Day

    On August 14, 1945, it was announced that Japan had surrendered unconditionally to the Allies, effectively ending World War II. Since then, both August 14 and August 15 have been known as “Victoryover Japan Day,” or simply “V-J Day.” The term has also been used for September 2, 1945, when Japan’s formal surrender took place aboard the U.S.S. Missouri, anchored in Tokyo Bay. Coming several months after the surrender of Nazi Germany, Japan’s capitulation in the Pacific brought six years of hostili
