Today was the beginning of the end, with all due respect to Churchill's call two years prior:

On this day in 1944, Supreme Allied Commander General Dwight D. Eisenhower gives the go-ahead for largest amphibious military operation in history: Operation Overlord, code-named D-Day, the Allied invasion of northern France.

By daybreak, 18,000 British and American parachutists were already on the ground. At 6:30 a.m., American troops came ashore at Utah and Omaha beaches. At Omaha, the U.S. First Division battled high seas, mist, mines, burning vehicles-and German coastal batteries, including an elite infantry division, which spewed heavy fire. Many wounded Americans ultimately drowned in the high tide. British divisions, which landed at Gold, and Sword beaches, and Canadian troops, landing at Juno beach, also met with heavy German fire, but by the end of the day they were able to push inland.

Despite the German resistance, Allied casualties overall were relatively light. The United States and Britain each lost about 1,000 men, and Canada 355. Before the day was over, 155,000 Allied troops would be in Normandy. However, the United States managed to get only half of the 14,000 vehicles and a quarter of the 14,500 tons of supplies they intended on shore.
