On 3 February, the 12th Armored Division moved south through 28th Division lines with the objective of linking up with the French I Corps and splitting the Colmar Pocket. Combat Command B (CCB) seized a bridgehead near Sundhoffen () and CCR advanced on the road between Colmar and Rouffach (). The following day, CCA captured Hattstatt () on the Colmar-Rouffach Road, but CCR found its way blocked by German defenses. On 5 February, CCA entered Rouffach and made contact with the 4th Moroccan Mountain Division of the French I Corps, some 17 days after French I Corps launched its assault. The same day, CCR entered the village of Herrlisheim-près-Colmar (), and so the 12th Armored Division attacked, for a second time, a town named Herrlisheim in Alsace (the battles of the 12th Armored Division in mid-January 1945, at Herrlisheim north of Strasbourg saw several battalions of the division manhandled by German troops in the Gambsheim bridgehead.) Thereafter, during the battle, the 12th Armored Division screened German exit routes from the Vosges Mountains and supported the 28th Division by fire.
