Continuing the pursuit along the Roer River valley to the Rhine, the companies targeted retreating columns of Germans, often overrun by speeding U.S. troops. On 11 March the battalion reached the Rhine in the vicinity of Sinzig. The companies deployed to protect the famed Remagen Bridge from enemy attack from the water, firing at boats and floating debris suspected of containing demolitions, and boat loads of enemy escaping across the river. Guns were sited to engage enemy targets across the Rhine. Company C was with the 38th Infantry protecting the south flank of the First Army against an enemy thrust at the bridge from the south.
