Inspired by the pioneering German use of large-scale airborne formations during the Battle of France in 1940 and later the invasion of Crete in 1941, the various Allied powers decided to raise airborne units of their own. One of the resultant five American and two British airborne divisions, the 11th Airborne Division, was officially activated on 25 February 1943 at Camp Mackall in North Carolina, under the command of Major General Joseph Swing. As formed, the division consisted of the 511th Parachute Infantry Regiment, the 187th Glider Infantry Regiment and the 188th Glider Infantry Regiment, and with a complement of 8,321 men was around half the strength of a regular U.S. infantry division of World War II.
