Its final exploits came when the 42nd Division relieved the 1st Infantry Division during the 3rd phase of the Meuse-Argonne offensive. Attacking against a well-entrenched enemy in terrible terrain without support from units on its flanks, the regiment suffered heavy casualties while moving forward and captured Hill 252 overlooking the Meuse River on 7 November. Once again, it was the tip of the spear of the American First Army. The war ended four days later with the signing of the Armistice, but the 69th then served as occupation troops in Remagen before returning to New York in the spring of 1919.
