The 10th Armored Division landed at Cherbourg on September 23, 1944, trained at Teurtheville, and entered combat in early November in the Fort Driant sector, helping contain German forces around the Metz fortress line. In mid-November it moved into the Saar-Moselle fighting: CCB crossed at Thionville and CCA at Malling, then CCA crossed the Nied near Filstroff. The advance toward Saarburg and Merzig ran into the Orscholz Switch Line, counterattacks, and repeated fighting around Nennig, Tettingen, Borg, Merzig, and Dreisbach before the division completed its west-bank clearing operations on December 2.

The Ardennes emergency pulled the division north to Luxembourg on December 17. Combat Command B reached Bastogne before the encirclement closed and fought in the critical outer delaying actions around Longvilly, Noville, Bras, Neffe, and the approaches to the town. CCA shifted toward Echternach, then after relief by the 4th Infantry Division helped form CCX with elements of the 9th Armored Division in the Waldbillig sector. The division was not alone at Bastogne, but its armored teams bought valuable time for the 101st Airborne Division and other defenders to form the perimeter. After relief in Luxembourg on December 26, the division held defensive positions east of the Saar and briefly returned to the Bastogne sector in January around Noville and Samree.

In February the division returned to XX Corps for the Saar-Moselle Triangle. With the 94th Infantry Division and attached RCT 376, it drove through the triangle, forced crossings near Ockfen and Taben, joined the Ockfen and Serrig bridgeheads, and pushed on Trier. CCA entered Trier and seized the Moselle bridge intact on March 1-2. The division then fought through the Ruwer, Kyll, Salm, Wittlich, and Bullay sequence before a short rehabilitation at Trier.

Its last campaign carried it from the Prims to Landau, across the Rhine and Neckar, and into the Heilbronn-Crailsheim region. The Crailsheim salient proved overextended and was abandoned after German counterattacks, but the division resumed the advance through the Kocher, Schwaebisch Hall, Rems, Kirchheim, and the Danube crossing at Ehingen. At the end of April it crossed near Schongau and Fuessen, sent CCA toward Partenkirchen and Klais, and pushed CCB beyond Reutte toward Fern Pass. There the division halted while the 103rd and 44th Infantry Divisions passed through toward Innsbruck and Imst.
