Operation Torch was the first joint military action undertaken by the Allies in World War II. This was the springboard for the idea, formed by British Prime Minister Winston Churchill, of attacking the "soft underbelly of Europe" before attempting a cross-channel attack from England onto mainland Europe. The main objective of Torch was to seize French Northwest Africa and, for political reasons, the Americans would lead operation. The airborne segment of the operation entailed flying 1,500 miles from England to seize two French airfields near Oran.
