On 18 August, the battalion once again was on the move, supporting the division in helping to protect the southern shoulder of the Falaise pocket. Soon thereafter, German resistance in western France collapsed, and the tankers road-marched in battalion formation due east across France and reached Bruyères-le-Châtel by early morning on 26 August. The companies were again attached to the regimental combat teams of the 9th Infantry Division and crossed the Seine the following day north of Ponthierry and at Melun at crossings established by the 7th Armored Division. As the battalion continued to pursue the Germans north and east of the Seine, Company D was reconstituted and attached to the division reconnaissance troop to screen the division front as they crossed the Aisne River between Reims and Laon. The battalion supported the division as it continued to moved first north in support of the encirclement of Mons, crossing into Belgium on 2 September between Fourmies and Chimay. Then turning northeast, the battalion advanced about 30 km per day, encountering continued sporadic resistance in the form of mined roadblocks, demolished bridges and mobile strong points. The tankers followed a route south of Charleroi, Namur and Liège to Eupen and crossed into Germany near Roetgen on 14 September 1944.
