These March 1944 top-secret Allied messages and meeting minutes document an important debate over the relationship between Operation Overlord, the planned invasion of Normandy, and Operation Anvil, the proposed amphibious invasion of southern France. Supreme Allied Commander Dwight D. Eisenhower concludes that Anvil, as originally planned, was no longer practical because sufficient landing craft and fresh troops would not be available. With resources for Overlord already extremely tight, Eisenhower recommends reducing Anvil and transferring additional landing ships and craft from the Mediterranean to Britain to strengthen the Normandy invasion.

The documents also reveal disagreement among senior Allied commanders over what should replace the original Anvil plan. Eisenhower emphasizes that the primary objective in the Mediterranean should be to contain and defeat the greatest possible number of German divisions, thereby preventing their transfer to France. He favors continuing pressure in Italy, including efforts to capture Rome, while preserving the possibility of an amphibious assault against southern France later in the summer if conditions and resources permitted.

The debate also reflects larger Anglo-American strategic differences. British leaders questioned committing themselves months in advance to a specific landing in southern France, while American leaders remained strongly committed to Anvil as an operation supporting Overlord. General George C. Marshall informed Eisenhower that the U.S. Chiefs of Staff opposed diverting landing craft from the Pacific and continued to favor launching Anvil by July while maintaining pressure against German forces in Italy.

The documents provide a valuable look at Eisenhower’s efforts to balance competing Allied priorities, scarce amphibious resources, and Mediterranean operations while ensuring that Operation Overlord received the forces necessary for the D-Day invasion.
