View images from the Italian Campaign of World War II, including the United States 442nd Infantry Regiment, composed almost entirely of men of Japanese-American ancestry, who fought with distinction and valor. In 1943, after the Axis Powers of Germany and Italy failed to secure North Africa, Allied forces, led by the United States and Britain, invaded Sicily, forcing Italy to surrender. But German troops held fast to the Italian mainland. The Italian Campaign of World War II began in 1943 and lasted until May of 1945. The battles were fierce and costly for the Allied troops.
