On 11 August, units of the battalion began moving north with the 90th as the division sought to close in on the southern side of the pincer which closed the Falaise pocket. The battalion continued to support the infantry regiments, and helped repel several armored and infantry attacks in the areas around Le Bourg-Saint-Leonard, Chambois and St. Eugenie; between 16 and 21 August, they accounted for thirty-four tanks, twenty-three self-propelled guns, nine halftracks and sixteen artillery pieces destroyed or captured, with over five hundred prisoners taken and fifteen men awarded Silver Stars.
