In December 1944, the Germans launched a surprise counteroffensive, the Battle of the Bulge, which the Allies turned back in early 1945 after Eisenhower repositioned his armies and improved weather allowed the Army Air Force to engage. German defenses continued to deteriorate on both the Eastern Front with the Red Army and the Western Front with the Western Allies. The British wanted to capture Berlin, but Eisenhower decided it would be a military mistake for him to attack Berlin, and said orders to that effect would have to be explicit. The British backed down but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow. The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in a very large-scale bloody battle, and the Germans finally surrendered on May 7, 1945.
