Later that day, Winters led an attack that destroyed a battery of German 105mm howitzers, which were firing onto the causeways that served as the principal exits from Utah Beach. The Americans estimated that the guns were defended by about a platoon of 50 German troops, while Winters had 13 men. This action south of the village of Le Grand-Chemin, called the Brécourt Manor Assault, has been taught at the military academy at West Point as an example of a textbook assault on a fixed position by a numerically inferior force. In addition to destroying the battery, Winters also obtained a map that showed German gun emplacements near Utah Beach.
