Warren, Jr., distinguished himself at the cost of his life above and beyond the call of duty. On this date while moving through a rubber plantation to reinforce another friendly unit, Company C came under intense fire from a well fortified enemy force. Disregarding his own safety, Lieutenant Warren with several of his men began maneuvering through the hail of enemy fire toward the hostile positions. When he had come to within six feet of one of the enemy bunkers and was preparing to toss a grenade into it, an enemy grenade was suddenly thrown into the middle of his small group. Thinking only of his men, Lieutenant Warren fell in the direction of the grenade, thus shielding those around him from the blast. His action, performed at the cost of his own life, saved three of his men from serious or mortal inury. First Lieutenant Warren’s ultimate action of sacrifice to save the lives of his men was in keeping with the highest traditions of the military service and reflect great credit on him, his unit, and the United States Army. | By direction of the President, on 8 September 1970, the Medal of Honor for conspicuous gallantry above and beyond the call of duty was awarded to First Lieutenant John E. Warren, Jr.
