'Cadillac' was an Allied major air-drop delivery of weapons, ammunition and other supplies to the French resistance forces in the Vercors massif area German-occupied France (14 July 1944).

The drop was made by some 144 Boeing B-17 Flying Fortress four-engined heavy bombers of Lieutenant General James H. Doolittle’s US 8^th AAF supplied by Major General Earle E. Partridge’s 3^rd Bombardment Division, using Brigadier General Frederick W. Castle’s 4^th Combat Bombardment Wing (94^th, 385^th and 447^th Bombardment Groups), Colonel Edgar M. Wittan’s 13^th Combat Bombardment Wing (95^th, 100^th and 390^th Bombardment Groups) and Brigadier General Archie J. Old’s 45^th Combat Bombardment Wing (96^th, 388^th and 452^nd Bombardment Groups), each loaded with 400 lb (181 kg) parachute-retarded supply containers, and escorted by about 200 Supermarine Spitfire single-engined fighters of the Royal Air Force. The bombers made their drop runs in groups of 12 at an altitude of only 350 ft (105 m) above the marked drop zones, and the accuracy of the delivery was therefore notably high.

The 3^rd Bombardment Wing flew four such 'carpetbagger' missions ('Zebra' on 25 June, 'Cadillac, 'Buick' on 1 August and 'Grassy' on 9 September), in the process flying 792 sorties of which 465 successfully delivered 115 agents, 5,439 weapons containers, 2,707 other packages, several thousands of leaflets and 17 hampers of live messenger pigeons.
