The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Soldier’s Medal to Sergeant Louis J. D’Aloisio, United States Army, for heroism at the risk of life not involving conflict with an armed enemy as a member of Company H, 2d Battalion, 311th Regiment (BCT), 78th Division (Tng), on 31 May 1957, at Mill Creek Range, Fort Knox, Kentucky. While instructing a trainee in the throwing of a live fragmentation grenade, Sergeant D’Aloisio observed that the nervous trainee activated the firing mechanism of the grenade by releasing the safety lever and immediately re-depressing it. The act of releasing the safety lever allowed the striker to rotate over and strike the primer, igniting the delayed train. The characteristic pop of ignition was not heard because of the roar of tank firing at a nearby range. Immediately commanding the trainee to “throw” and noticing the trainee’s lack of action, Sergeant D’Aloisio, with complete disregard for his personal safety, leaped to the trainee, wrested the grenade from his hand, tossed it over the barrier toward the firing range, and threw himself on top of the trainee. The grenade exploded approximately 5 meters from them in the air, just over the concrete barrier. Sergeant D’Aloisio’s quick action and utter disregard for his personal safety demonstrated unusual courage and reflect great credit upon himself, United States Army, and the military service.
