The President of the United States of America takes pleasure in presenting the Navy Cross to Sergeant Walter H. Allen (MCSN: 284778), United States Marine Corps, for extraordinary heroism and devotion to duty while serving as a Squad Leader of Company H, Third Battalion, Twenty-Sixth Marines, FIFTH Marine Division, in action against enemy Japanese forces on Iwo Jima, Volcano Islands, 22 February 1945. While leading his squad through heavy small-arms and artillery fire in an assault on a strongly defended enemy position, Sergeant Allen and his men became isolated in front of his platoon which received heavy casualties, including the Platoon Leader. With his squad vulnerable on the flanks and in the rear, he repeatedly exposed himself to the heavy fire while deploying his squad to cover the platoon front and, after contacting units on his left and right, renewed the attack on his own initiative, knocking out at least two pillboxes and many other hostile installations. He then sent word of the situation to his Company Commander and, despite additional casualties among his men, captured the enemy position and continued to advance along the platoon front until ordered to stop. His aggressive leadership, determined fighting spirit and courageous devotion to duty were in keeping with the highest traditions of the United States Naval Service.
