The 37th moved out in a downpour on 9 November 1944 to deprive Hitler of the industrial Saar River Valley. On 11 November 1944 the 37th was caught on the road and lost six tanks because they could not maneuver off-road due to the bottomless mud. On 8 December 1944 the 37th passed through the old French Maginot Line and took Singling. Two days later it was relieved again, by elements of the 12th Armored Division, and sent to the rear for another rest, although not so far back that elements of the battalion were not in intermittent contact with German forces.
