| − | The British Chiefs of Staff charged Admiral Lord [[Louis Mountbatten]] and his Combined Operations Headquarters in September 1941 with investigating the feasibility of amphibious operations in the European theater of the war. Earlier, Admiral Sir Roger Keyes had undertaken some planning for commando raids, but Mountbatten was to do more. "You are to prepare for the invasion of Europe," British Prime Minister [[Winston S. Churchill]] told him. "You must devise and design the appliances, the landing craft, and the technique...The whole of the South Coast of England is a bastion of defense against the invasion of Hitler; you've got to turn it into the springboard for our attack." | + | The British Chiefs of Staff charged Admiral Lord [[Louis Mountbatten]] and his Combined Operations Headquarters in September 1941 with investigating the feasibility of amphibious operations in the European theater of the war.

| | American planners began formal cooperation with Britain in December 1941, just after the Japanese attack at [[Attack on Pearl Harbor|Pearl Harbor]] and the German and Italian declarations of war against the United States. In compliance with earlier, informal understandings, the two partners agreed to put first the defeat of [[Germany]] and its ally [[Italy]] if forced to wage a two-front war against both those nations and Japan. Shortly thereafter, British planners drafted a proposal, code-named ROUNDUP, for an attack across the English Channel into France. The assault would come only after a series of major campaigns on the periphery of Europe, in [[Scandinavia]], the [[Mediterranean Sea]], the [[Balkans]], and the [[Soviet Union]], where the Germans would have difficulty massing their power. Once bombing, blockade, partisan uprisings, and the fighting on those other fronts had weakened the enemy sufficiently, ROUNDUP, or something like it, would begin. | | American planners began formal cooperation with Britain in December 1941, just after the Japanese attack at [[Attack on Pearl Harbor|Pearl Harbor]] and the German and Italian declarations of war against the United States.
