This top-secret March 31, 1944 message from General George C. Marshall to General Dwight D. Eisenhower discusses Allied strategy in the Mediterranean and its relationship to Operation Overlord, the planned invasion of Normandy. Marshall reports the U.S. Chiefs of Staff’s response to British proposals concerning Operation Anvil, the planned Allied invasion of southern France. The Americans opposed diverting landing craft from the Pacific unless the British firmly intended to launch Anvil with two divisions by July 10 in support of Overlord.

Marshall emphasizes that Mediterranean operations should support, rather than weaken, the Normandy invasion. He argues that continued offensive pressure in Italy could force Germany to keep substantial forces in the Mediterranean and prevent their transfer to northern France. He also supports maintaining a credible amphibious threat against southern France around the time of Overlord. The message further addresses command arrangements, arguing that the Allied commander in the Mediterranean should receive clear instructions without delay. Marshall rejects delaying action based on uncertainty surrounding the Anzio campaign and insists that existing Mediterranean directives must be revised. The message illustrates the difficult strategic decisions Allied leaders faced in allocating troops, landing craft, and resources while ensuring that Mediterranean operations contributed to the success of Overlord.
