The President of the United States of America, in the name of Congress, takes pride in presenting the Medal of Honor (Posthumously) to Private First Class Walter Carleton Monegan, Jr. (MCSN: 658171), United States Marine Corps, for conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty from 17 to 20 September 1950, while serving as a rocket gunner attached to Company F, Second Battalion, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces near Sosa-ri, Korea. Dug in on a hill overlooking the main Seoul highway when six enemy tanks threatened to break through the battalion position during a predawn attack on 17 September, Private First Class Monegan promptly moved forward with his bazooka, under heavy hostile automatic weapons fire and engaged the lead tank at a range of less than 50 yards. After scoring a direct hit and killing the sole surviving tankman with his carbine as he came through the escape hatch, he boldly fired two more rounds of ammunition at the oncoming tanks, disorganizing the attack and enabling our tank crews to continue blasting with their 90-mm guns. With his own and an adjacent company’s position threatened by annihilation when an overwhelming enemy tank-infantry force bypassed the area and proceeded toward the battalion command post during the early morning of 20 September he seized his rocket launcher and, in total darkness, charged down the slope of the hill where the tanks had broken through. Quick to act when an illuminating shell lit the area, he scored a direct hit on one of the tanks as hostile rifle and automatic-weapons fire raked the area at close range. Again exposing himself, he fired another round to destroy a second tank and, as the rear tank turned to retreat, stood upright to fire and was fatally struck down by hostile machinegun fire when another illuminating shell silhouetted him against the sky. Private First Class Monegan’s daring initiative, gallant fighting spirit and courageous devotion to duty were contributing factors in the success of his company in repelling the enemy, and his self-sacrificing efforts throughout sustain and enhance the highest traditions of the U.S. Naval Service. He gallantly gave his life for his country.
