The invasion was originally given the code name of "Operation Anvil", but was changed to "Operation Dragoon" before the landing. In March 1944, Major General Alexander Patch, a highly experienced and competent commander, was assigned to command the Seventh Army, which moved to Naples, Italy, the following July. On 15 August 1944, elements of the Seventh Army assaulted the beaches of southern France in the St. Tropez and St. Raphael area. (Patch was promoted to Lieutenant General three days later.) On 15 September, the Seventh was put under the field control of the 6th Army Group, under Lieutenant General Jacob L. Devers. The 6th Army Group also included the French First Army. Within one month, the Seventh Army, which by then employed three American divisions, five French divisions and the 1st Airborne Task Force, had advanced 400 miles and joined with the Allied forces coming south from Normandy. In the process, the Seventh Army had liberated Marseilles, Lyon, Toulon and all of Southern France.
