<P> The war against Germany involved aid to Britain , her allies , and the Soviet Union , with the U.S. supplying munitions until it could ready an invasion force . U.S. forces were first tested to a limited degree in the North African Campaign and then employed more significantly with British Forces in Italy in 1943 -- 45 , where U.S. forces , representing about a third of the Allied forces deployed , bogged down after Italy surrendered and the Germans took over . Finally the main invasion of France took place in June 1944 , under General Dwight D. Eisenhower . Meanwhile , the U.S. Army Air Forces and the British Royal Air Force engaged in the area bombardment of German cities and systematically targeted German transportation links and synthetic oil plants , as it knocked out what was left of the Luftwaffe post Battle of Britain in 1944 . With the Soviets unstoppable in the east , and the Allies unstoppable in the west , Germany was squeezed to death . Berlin fell to the Soviets in May 1945 , and with Adolf Hitler dead , the Germans surrendered . </P>
