WW2 Event Timeline

  • Sino-Japanese War

    Sino-Japanese War
    In 1931, Japan, eager for the vast natural resources to be found in China and seeing her obvious weakness, invaded and occupied Manchuria. In the 1930’s the Chinese suffered continued territorial encroachment from the Japanese, using their Manchurian base. In 1937 skirmishing between Japanese and Chinese troops on the frontier led to what became known as the Marco Polo Bridge Incident.
  • Blitzkrieg

    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.
  • Invasion of Poland

    Invasion of Poland
    One of Adolf Hitler's first major foreign policy initiatives after coming to power was to sign a nonaggression pact with Poland in January 1934. This move was not popular with many Germans who supported Hitler but resented the fact that Poland had received the former German provinces of West Prussia, Poznan, and Upper Silesia under the Treaty of Versailles after World War I.
  • Operation Barbarossa

    Operation Barbarossa
    Operation Barbarossa was an invasion when Hitler sent his troops to the Soviet territory. At this point the German forces was at its highest point yet. This invasion was a crutial turning point in World War 2.
  • Pearl Harbor

    Pearl Harbor
    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

    Wannsee Conference
    On January, 20, 1942, Reinhard Heydrich, Himmler's second in command of the SS, convened the Wannsee Conference in Berlin with 15 top Nazi bureaucrats to coordinate the Final Solution (Endlösung) in which the Nazis would attempt to exterminate the entire Jewish population of Europe, an estimated 11 million persons.
  • Operation Gomorrah

    Operation Gomorrah
    On this day in 1943, British bombers raid Hamburg, Germany, by night in Operation Gomorrah, while Americans bomb it by day in its own “Blitz Week.”
    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 destruc
  • D-Day

    D-Day
    During World War II (1939-1945), the Battle of Normandy, which lasted from June 1944 to August 1944, resulted in the Allied liberation of Western Europe from Nazi Germany’s control. Codenamed Operation Overlord, the battle began on June 6, 1944, also known as D-Day, when some 156,000 American, British and Canadian forces landed on five beaches along a 50-mile stretch of the heavily fortified coast of France’s Normandy region.
  • Battle of the Bulge

    In December 1944, Adolph Hitler attempted to split the Allied armies in northwest Europe by means of a surprise blitzkrieg thrust through the Ardennes to Antwerp. Caught off-guard, American units fought desperate battles to stem the German advance at St.-Vith, Elsenborn Ridge, Houffalize and Bastogne. As the Germans drove deeper into the Ardennes in an attempt to secure vital bridgeheads, the Allied line took on the appearance of a large bulge, giving rise to the battle’s name.
  • Operation Thunderclap

    ‘Operation Thunderclap’ had been under discussion within the Allied Command for some time, the proposal was to bomb the eastern-most cities of Germany to disrupt the transport infrastructure behind what was becoming the Eastern front. Also to demonstrate to the German population, in even more devastating fashion, that the air defences of Germany were now of little substance and that the Nazi regime had failed them. At Yalta Churchill had promised to do more to support the Soviet forces moving we
  • 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. Despite the difficulty of the conditions, the marines wiped out the defending forces.
  • Battle of Okinawa

    Last and biggest of the Pacific island battles of World War II, the Okinawa campaign (April 1—June 22, 1945) 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.
  • Victory in Europe

    The eighth of May spelled the day when German troops throughout Europe finally laid down their arms: In Prague, Germans surrendered to their Soviet antagonists, after the latter had lost more than 8,000 soldiers, and the Germans considerably more; in Copenhagen and Oslo; at Karlshorst, near Berlin; in northern Latvia; on the Channel Island of Sark—the German surrender was realized in a final cease-fire. More surrender documents were signed in Berlin and in eastern Germany.
  • Atomic Bomb

    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.
  • V-J 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.
