The 3rd Division continued its south and east sidestepping maneuver. On the evening of 29 January, divisional artillery fired 16,000 105 mm and 155 mm rounds during a three-hour preparation for the assault of the 7th and 15th Infantry Regiments south across the Colmar Canal. The infantry crossed between 21:00 and midnight. After the crossings were secured, engineers began the construction of three Bailey bridges over the canal to enable armored vehicles to cross. The following day, the French armored combat commands CC4 and CC5 (both of the 5th Armored Division) crossed the canal, with CC4 supporting the U.S. 7th Infantry and CC5 supporting the U.S. 15th Infantry. Soon thereafter, the 15th Infantry and CC5 took Urschenheim in a brisk action, while the 7th Infantry was held up in front of Horbourg. The same day, the 254th Infantry attacked east toward Artzenheim with support of the French armored combat command CC6, but the Germans employed artillery support and dug-in Jagdpanther tank destroyers to parry the thrust, destroying six French tanks and four halftracks. Artzenheim was taken by the French II Corps on 1 February.
