On 16 June, the 45th Division withdrew for rest in preparation for other operations. At this time, VI Corps was attached to the Seventh Army, under Lieutenant General Alexander Patch, itself part of the 12th Army Group under Lieutenant General Jacob L. Devers. The 45th, 36th, and 3rd Infantry Divisions were pulled from the line in Italy in preparation for Operation Dragoon (formerly "Anvil"), the invasion of southern France. "Dragoon" was originally planned to coincide with the Normandy landings in the north, but was delayed until August because of a shortage of landing craft.
