The President of the United States of America takes pride in presenting the Bronze Star Medal (Posthumously) to Lieutenant Commander Edward Francis O’Brien, Jr. (NSN: 0-85074), United States Navy, for heroic service on board the U.S.S. THRESHER (SS-200) during action against enemy Japanese forces. On the THIRD, FOURTH, FIFTH, SIXTH and SEVENTH War Patrols when the THRESHER was subjected to twenty attacks in which a total of 160 bombs and depth charges were dropped, Lieutenant Commander O’Brien manned his battle station with outstanding professional skill. Through prompt action and efficient direction, he was responsible for the immediate repair or minimization of all damage sustained, thereby rendering invaluable service to his Commanding Officer by maintaining his vessel in effective fighting condition. The exemplary conduct and valiant devotion to duty displayed by Lieutenant Commander O’Brien under extremely hazardous circumstances were an inspiration to his associates and was in keeping with the highest traditions of the United States Naval Service.
