At the start of the offensive, the First and Third U.S. Armies were separated by about . American progress in the south was also restricted to about a kilometer a day. The majority of the German force executed a successful fighting withdrawal and escaped the battle area, although the fuel situation had become so dire that most of the German armor had to be abandoned. On 7 January 1945, Hitler agreed to withdraw all forces from the Ardennes, including the "SS Panzer" divisions, thus ending all offensive operations. However, considerable fighting went on for another 3 weeks; St. Vith was recaptured by the Americans on 23 January and the last German units participating in the offensive did not return to their start line until 25 January.
