American infantrymen views sample of U.S. artillery firepower. A U.S. infantry soldier gazes at a hole blasted by U.S. artillery through a solid steel-reinforced concrete wall of a Maginot Line fortress on the French frontier. The accuracy of American fire is attested to by the eight inch "dud" shell lying in the left foreground below a gun turret. After five days of pounding from the ground and air, the German withdrew.
