The President of the United States of America takes pleasure in presenting a Second Gold Star in lieu of a Third Award of the Distinguished Flying Cross to Lieutenant Colonel John Bernard Maas, Jr. (MCSN: 0-9017), United States Marine Corps, for extraordinary achievement while participating in aerial flight against the enemy in Korea from 10 January 1953 to 13 January 1953, during a series of massed aerial assaults on a heavily defended bridge complex in the vicinity of Sinanju. Confronted by intense defensive fire and under constant threat of attack by numerically superior jet interceptors, Lieutenant Colonel Mass, Commanding Officer of a Marine Jet Fighter Squadron of jet fighter-bombers led his squadron on four successive bombing missions against the major enemy objective. On each of these strikes, he led his flight in coordinated bombing and strafing attacks against the enemy. Diving through accurate and intense barrages of hostile radar-controlled anti-aircraft fire, he repeatedly scored direct bomb hits that clearly marked the targets for the remainder of the flight. Lieutenant Colonel Mass’ exceptional bombing accuracy and exemplary leadership were responsible for the success of four separate strikes that destroyed three bridges, twenty boxcars and inflicted numerous rail cuts. His courageous conduct, outstanding initiative and steadfast devotion to duty throughout reflected great credit upon himself and were in keeping with the highest traditions of the United States Naval Service.
