The Battle of the Rhine refers to a series of military operations during World War II, primarily occurring in March 1945. This battle involved the Allied forces, including the United States and Britain, crossing the Rhine River to penetrate deep into Germany. The successful crossing marked a significant turning point, as it allowed the Allies to advance toward Berlin. The battle was characterized by intense fighting and strategic planning, with the Allies aiming to break through the German defenses. The operation culminated in the capture of key cities along the Rhine, leading to the eventual defeat of Nazi Germany in May 1945.
