In August 1944, the 1103d was transferred to General George S. Patton's Third Army. Throughout the fall of 1944, the 1103d protected captured bridges on the Loire River, bridged the Moselle River, and breached the massive and cubicled Metz forts for the assaulting forces. During these engagements, the 1103d earned two additional campaign streamers for the Northern France and Ardennes-Alsace Campaigns.
