summaryShort: On June 6, 1944, Allied forces launched Operation Overlord, landing 156,000 troops on the Normandy coast to establish a beachhead in Nazi-occupied France. The invasion marked the beginning of the end for Nazi Germany in Western Europe.
summaryLong: |-
  Operation Overlord began before dawn on June 6, 1944, when American, British, and Canadian forces crossed the English Channel to assault five beaches code-named Utah, Omaha, Gold, Juno, and Sword. Supreme Commander Dwight D. Eisenhower had postponed the invasion once due to bad weather; the operation finally proceeded on what meteorologists predicted would be a narrow window of acceptable conditions. The landings involved 5,000 ships and landing craft, 11,000 aircraft, and eventually 156,000 troops on the first day alone—the largest amphibious assault in history.

  The beach assaults came after weeks of deception campaigns designed to convince Nazi high command that the invasion would occur elsewhere, likely near Pas-de-Calais. Operation Fortitude, which fed false intelligence to German planners, proved devastatingly effective; even after D-Day, Hitler kept significant forces pinned in the wrong location, waiting for a phantom second landing that never came. German Field Marshal Erwin Rommel, commanding coastal defenses, was away from his post on June 6, attending his wife's birthday celebration in Germany.

  Cassualties mounted quickly. Omaha Beach saw the bloodiest fighting; the U.S. 1st and 29th Infantry Divisions suffered roughly 2,000 casualties there in a single day. Overall, Allied forces sustained approximately 10,000 casualties on June 6—about 4,400 killed. German losses are harder to pin down but certainly numbered in the thousands. The fighting would continue inland for months; the Allies didn't fully secure Normandy until late August, after breaking out from the beachhead at Saint-Lô and Caen.

  The invasion fundamentally shifted the war's trajectory. For the first time since 1940, Germany faced a major two-front conflict: Soviet forces pressing from the east, now an unstoppable Western advance from the beaches. Hitler's strategic situation became untenable, though he wouldn't accept it. The Normandy landings proved that a successful amphibious invasion of fortified enemy territory was possible—a lesson that would shape military thinking for decades. By September 1944, most of France was liberated; by May 1945, Germany had surrendered unconditionally.
lede: On June 6, 1944, over 150,000 Allied troops stormed five beaches in Normandy, France, breaking through Nazi defenses in the largest amphibious invasion ever attempted. The operation, code-named Overlord, followed years of careful planning and deception and opened a Western front that would lead directly to Nazi Germany's defeat less than a year later.

zeitgeistNote: 1944 was dominated by military news and shortages on the home front. Radio was the primary real-time information source; newsreels provided dramatic footage of the invasion. The cultural mood oscillated between hope for imminent victory and anxiety about the human cost. Rationing in Britain and the U.S. remained strict, and casualty lists were a daily fact of life. Popular culture emphasized duty, sacrifice, and eventual triumph.
