He proposed this because he wanted the Allies to take some pressure off the Soviet Union because they were doing most of the fighting with the Germans at that point. The invasion of France proved to be the first successful amphibious attack made by the Allies. An amphibious attack is one made with joint army and navy attacks on a hostile shore. Only the Germans and Japanese had managed to do this successfully, but the invasion and eventual win of France might not have been possible without the attack the Allies had staged. Hitler was taken by surprise at the attack on the beach head, and this is probably why the Allies had managed to win France
