Churchill argued for the invasion of Italy in 1943, then Overlord in 1944, on the basis that Overlord was physically impossible in 1943 due to lack of shipping and it would be unthinkable to do anything major until it could be launched. Churchill proposed to Stalin a moving westwards of Poland, which Stalin accepted, which gave the Poles industrialized German land to the west and gave up marshlands to the east, while providing a territorial buffer to the Soviet Union against invasion. Churchill's plan involved a border along the Oder and the Eastern Neisse, giving Poland a fair compensation for the Eastern Borderlands in Churchill's view.
