Supreme Headquarters Allied Expeditionary Force (SHAEF)

The Supreme Headquarters Allied Expeditionary Force (SHAEF) was the command organization responsible for planning and executing the Allied military operations in Western Europe during World War II. Led by General Dwight D. Eisenhower, SHAEF coordinated the efforts of multiple Allied nations, including the United States, Britain, and Canada, to launch and oversee the D-Day invasion of Normandy in 1944. Its role was to ensure unified strategic planning, logistical support, and operational control for the allied offensive that ultimately led to the defeat of Nazi Germany.
