The original focus was to be a combined Overlord – Anvil operation originally scheduled for May 1944 but at the time Winston Churchill felt that continued operations in Italy and elsewhere in the Mediterranean would afford better use of resources, furthermore any amphibious operation would detract from the Normandy landings. There was much controversy and Anvil – Dragoon became embroiled in a larger Anglo-American disagreement on strategy. Two major events, the fall of Rome in early June 1944 and the speed of the push south of the Normandy landings renewed the prospects of a Southern France invasion also supplying the Normandy offensive was becoming a major problem due the fact that the artificial harbour on Omaha Beach in the north was destroyed by a violent storm and the Port of Cherbourg was demolished by the Germans before it was captured by the Americans. This made it all the more important to open up a supply route from the south.
In July 1944 Anvil was officially revived and re-named Dragoon with a date set for the operation of 15th August 1944.
