German Blitzkrieg 1939-1940
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. -
Germany's invasion of Poland
1.5 million German troops invade Poland all along its 1,750-mile border with German-controlled territory. Simultaneously, the German Luftwaffe bombed Polish airfields, and German warships and U-boats attacked Polish naval forces in the Baltic Sea. Nazi leader Adolf Hitler claimed the massive invasion was a defensive action, but Britain and France were not convinced. On September 3, they declared war on Germany, initiating World War II. -
Operation Bararossa
Hitler launched his armies eastward in a massive invasion of the Soviet Union: three great army groups with over three million German soldiers, 150 divisions, and three thousand tanks smashed across the frontier into Soviet territory. The invasion covered a front from the North Cape to the Black Sea, a distance of two thousand miles. -
Pearl Harbor
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 almost 200 airplanes. More than 2,000 Americans soldiers and sailors died in the attack, and another 1,000 were wounded. -
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. -
D-Day
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. -
Liberation of concentration camps
The Germans had dismantled these camps in 1943, after most of the Jews of Poland had already been killed. The Soviets liberated Auschwitz, the largest killing center and concentration camp, in January 1945. -
Battle of Bulge
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. -
Battle of Iwo Jima
Marines wiped out the defending forces after a month of fighting, and the battle earned a place in American lore with the publication of a photograph showing the U.S. flag being raised in victory. -
VE Day
The day when German troops throughout Europe finally laid down their arms. -
Dropping of atomic bombs
American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima. The explosion wiped out 90 percent of the city and immediately killed 80,000 people; tens of thousands more would later die of radiation exposure. -
VJ Day
Japan had surrendered unconditionally to the Allies, effectively ending World War II.
