Japanese invasion
The war was the result of a decades-long Japanese imperialist policy aimed at expanding its influence politically and militarily in order to secure access to raw material reserves and other economic resources in the area, particularly food and labour. Before 1937, China and Japan fought in small, localized engagements, so-called "incidents". In 1931, the Japanese invasion of Manchuria by Japan's Kwantung Army followed the Mukden Incident. The last of these incidents was the Marco Polo Bridge Inc -
Germany's invasion of Poland
On September 1, 1939, Germany invaded Poland. The Polish army was defeated within weeks of the invasion. From East Prussia and Germany in the north and Silesia and Slovakia in the south, German units, with more than 2,000 tanks and over 1,000 planes, broke through Polish defenses along the border and advanced on Warsaw in a massive encirclement attack. After heavy shelling and bombing, Warsaw surrendered to the Germans on September 27, 1939. Britain and France, standing by their guarantee of Pol -
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. German forces tried out the blitzkrieg in Poland in 1939 before successfully employing the tactic with invasions of Belgium, the Netherlands and France in 1940. The blitzkrieg was -
Fall of Paris
On this day in 1940, Parisians awaken to the sound of a German-accented voice announcing via loudspeakers that a curfew was being imposed for 8 p.m. that evening-as German troops enter and occupy Paris. -
Operation Barbarossa
Operation Barbarossa was the code name for Nazi Germany's invasion of the Soviet Union during World War II, commencing on 22 June 1941. Over the course of the operation, about four million soldiers of the Axis powers invaded Soviet Russia along a 2,900 km (1,800 mi) front, making it the largest invasion in the history of warfare. In addition to troops, the Germans employed some 600,000 motor vehicles and 625,000 horses. The operation was driven by Adolf Hitler's -
Pearl Harbor

The base was attacked by 353 Japanese fighter planes, bombers, and torpedo planes in two waves, launched from six aircraft carriers.All eight U.S. Navy battleships were damaged, with four being sunk.

Battle of Midway
On this day in 1942, the Battle of Midway–one of the most decisive U.S. victories against Japan during World War II–begins. During the four-day sea-and-air battle, the outnumbered U.S. Pacific Fleet succeeded in destroying four Japanese aircraft carriers while losing only one of its own, the Yorktown, to the previously invincible Japanese navy. -
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
By dawn on June 6, thousands of paratroopers and glider troops were already on the ground behind enemy lines, securing bridges and exit roads. The amphibious invasions began at 6:30 a.m. The British and Canadians overcame light opposition to capture beaches codenamed Gold, Juno and Sword, as did the Americans at Utah Beach. U.S. forces faced heavy resistance at Omaha Beach, where there were over 2,000 American casualties. However, by day’s end, approximately 156,000 Allied troops had successfull -
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. -
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 -
Batlle 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. -
Battle of the Bulge
On December 16, three German armies (more than a quarter-million troops) launched the deadliest and most desperate battle of the war in the west in the poorly roaded, rugged, heavily forested Ardennes. The once-quiet region became bedlam as American units were caught flat-footed and fought desperate battles to stem the German advance at St.-Vith, Elsenborn Ridge, Houffalize and, later, Bastogne, which was defended by the 101st Airborne Division. The inexperienced U.S. 106th Division was nearly a -
Dropping of the Atomic Bombs
On this day in 1945, at 8:16 a.m. Japanese time, an American B-29 bomber, the Enola Gay, drops the world’s first atom bomb, over the city of Hiroshima. Approximately 80,000 people are killed as a direct result of the blast, and another 35,000 are injured. At least another 60,000 would be dead by the end of the year from the effects of the fallout. -
VE Day
On 30 April, Adolf Hitler, the Nazi leader, committed suicide during the Battle of Berlin. Germany's surrender, therefore, was authorized by his successor, Reichspräsident Karl Dönitz.

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
