 After reaching the crest of the hill, the platoon was pinned down by intense enemy machine-gun and small-arms fire.Locating 1 of these guns, which was dug in on a terrace on his immediate front, Pvt.Crawford, without orders and on his own initiative, moved over the hill under enemy fire to a point within a few yards of the gun emplacement and single-handedly destroyed the machine-gun and killed 3 of the crew with a hand grenade, thus enabling his platoon to continue its advance.
