The regiment, less the 3rd Battalion, was awarded the Presidential Unit Citation for its performance during Operation Cobra, the breakthrough of German positions west of Saint-Lô. The regiment and division fought in the Allied advance from Paris to the Rhine, crossing the German border in September. For its actions in the division's attack on the Siegfried Line in early October, the 2nd Battalion of the regiment received the Presidential Unit Citation. After the attack on the Siegfried Line stalled, the division held its positions along the Roer River and in December was ordered to the Ardennes after the German attack in the Battle of the Bulge.
