The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Private Harold E. Polk (MCSN: 291799), United States Marine Corps, for extraordinary heroism as a member of an assault rifle platoon serving with the Twenty-Second Marines (Reinforced), First Provisional Marine Brigade, during the attack against enemy Japanese-held Engebi Island, Eniwetok Atoll, Marshall Islands, 18 February 1944. When his platoon was held up by fierce enemy machine-gun and rifle fire, Private Polk realized the attack was coming from a pillbox and, on his own initiative, worked his way under devastating fire to the entrance of the Japanese emplacement, fused and ignited a bangalore torpedo and thrust it into the pillbox. During this valiant and daring action, Private Polk was mortally wounded by Japanese rifle and grenade fire but he had succeeded in destroying the hostile strongpoint with nineteen of its defenders. By his extreme bravery and indomitable fighting spirit he enabled his platoon to advance toward its objective. His outstanding devotion to duty throughout the action was in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
