On 15 August, it landed near St. Tropez as part of Operation Dragoon, attached to the 3rd Infantry Division, and pushed north through France along the Rhone Valley.

The division went into defensive positions on the Rhine after reaching Strasbourg on 26 November, and saw heavy fighting early in 1945 during the clearing of the Colmar Pocket.

It crossed the Rhine on 26 March, where its DD tanks were used as part of an amphibious assault, and then pushed into southern Germany with the 3rd Infantry.
