  • Nazi Germany invades the Soviet Union

    Under the codename Operation "Barbarossa," Nazi Germany invaded the Soviet Union on June 22, 1941 in the largest German military operation of World War II. Adolf Hitler had always regarded the German-Soviet nonaggression pact, signed on August 23, 1939, as a temporary tactical maneuver.

    Key American Events WWII

  • First American troops arrive in Europe, landing in Belfast

    America entered the war on the Allied side in December 1941, after the Japanese attack on Pearl Harbor and subsequent German declaration of war on the United States. Millions of men and thousands of planes and tanks were deployed to Britain, which became a base for American airmen flying bombing raids over Europe, a staging post for American troops on their way to fight in North Africa, and crucially the launching point for the D-Day invasions that began the liberation of Western Europe.
  • Battle of Coral Sea

    Battle of Coral Sea
    was a major naval battle in the Pacific Theater of World War II between the Imperial Japanese Navy and Allied naval and air forces from the United States and Australia
  • Battle of Midway

    was the most important naval battle of the Pacific Campaign of World War II
  • 'Dieppe Raid' ends in disaster for the Allies

    The Allied attack on the German-occupied port of Dieppe, on the northern French coast, had a variety of purposes. It would raise morale at a time when the war was going badly, it would show the Soviets that the western Allies could open a second front, and it would teach valuable lessons for the eventual full-scale invasion of Europe. It was a disaster. Of the 6,000 mainly Canadian troops who made it ashore, more than 4,000 were killed, wounded or taken prisoner.
  • Germany calls off the Battle of the Atlantic

    Allied merchant shipping losses to German 'U-boats' in the Atlantic had reached crisis levels in late 1942 to early 1943. At the Casablanca Conference in January 1943, Allied leaders allocated more resources to the battle. In March 1943, after a 'blackout' of several months, German U-boat ciphers were once again broken, allowing the new resources to be deployed to devastating effect. By May 1943, U-boat losses were so heavy that Kriegsmarine commander Admiral Karl Dönitz called off the battle.
  • Allies win the Battle of Monte Cassino after five months of fighting

    The battle centred on the ancient Italian monastery of Monte Cassino. The Allies were attempting to break through the German 'Gustav Line', which ran across Italy, south of Rome. The Germans sought to halt the Allied advance north by holding them at Monte Cassino. The bitter fighting lasted over five months, during which the monastery was reduced to rubble. By the time the Allies broke through, casualties numbered more than 54,000 Allied and 20,000 Germans troops.
  • Liberation of Rome

    Fighting in the Italian Campaign continued as theAllies made their way north through many Germandefensive positions. Notable for Canada was theBattle in the Liri Valley, with the ensuing liberationof Rome by the American army on June 5, 1944.
  • Allied forces land in Normandy on D-Day, starting the liberation of France

    The invasion of Europe - the largest amphibious invasion in history - succeeded in landing 150,000 troops on the beaches of Normandy on the first day, through a massive combined operation requiring hundreds of ships and total air superiority. Behind the lines, Allied paratroops seized key strategic targets, while the French resistance sabotaged rail and communication links. By the end of D-Day, five beachheads were secured, and the Allies had a foothold in France.
  • Allied forces are defeated at the Battle of Arnhem

    Operation Market Garden was a bold plan to land 30,000 Allied troops behind enemy lines and capture eight bridges spanning a network of waterways on the Dutch-German border near Arnhem. It would allow the Allies to outflank German border defences, opening the way for an advance into Germany and an early end to the war. A combination of factors, including faulty intelligence about German strength and bad weather, resulted in failure. More than 1,130 Allied troops were killed and 6,000 captured.
  • Hitler commits suicide

    The cause of death is suicide by a gunshot wound to the head and cyanide posioning. The lack of public information concerning the whereabouts of Hitler's remains, confused reports stemming from the dual method and other circumstances surrounding the event encouraged rumours that Hitler may have survived the end of World War II.
  • Victory in Europe Day (VE Day) - the war in Europe ends

    German forces had been utterly defeated by the end of April 1945. Adolf Hitler committed suicide on 30 April as Soviet forces closed in on his Berlin bunker. The German Grand Admiral Karl Dönitz surrendered to Allied General Dwight Eisenhower in France on 7 May. The following day was officially celebrated in Britain as Victory in Europe Day. The entire country came to a standstill as people celebrated the end of war.
  • Atomic Bomb - Hiroshima

    During the final stages of World War II in 1945, the United States conducted two atomic bombings against Japan in the cities of Hiroshima and Nagasaki. After six months of intense strategic fire-bombing of 67 Japanese cities the Japanese government ignored an ultimatum given by the Potsdam Declaration. By executive order of President Truman the U.S. dropped the nuclear weapon "Little Boy" on the city of Hiroshima on Monday, August 6, 1945.
  • Victory over Japan Day marks the end of World War Two

    On 6 August, an atomic bomb was dropped on the Japanese city of Hiroshima by the American bomber 'Enola Gay'. Three days later, a second bomb was dropped on the port city of Nagasaki. In all, 140,000 people perished. Less than a week later, the Japanese leadership agreed to an unconditional surrender, and the Emperor Hirohito broadcast his nation's capitulation over the radio. Victory over Japan day also marked the end of World War Two.
