The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Silver Star to Lieutenant Colonel Donald Keith Yost (MCSN: 0-5453), United States Marine Corps, for conspicuous gallantry and intrepidity as a Flight Leader and Pilot of a Plane in Headquarters Squadron TWELVE in action against enemy aggressor forces in Korea on 29 July 1951. Assigned the mission of leading a thirty-plane strike on heavily fortified military installations in the hostile capital of Pyongyang, Korea, Lieutenant Colonel Yost skillfully conducted the flight to the target area despite adverse flying conditions. In the face of intense and accurate, radar controlled anti-aircraft fire, he pressed home dangerous, low-level attacks to inflict maximum destruction on the enemy and, by his courageous example and leadership, inspired the members of the flight to carry out bold runs on the hostile positions. Skillfully employing offensive as well as defensive tactics while coordinating the fire power of his group, he was primarily responsible for demolishing the enemy’s radio station and an adjacent power plant with minimum damage to the aircraft in his group. An aggressive and daring airman, Lieutenant Colonel Yost, by his indomitable fighting spirit and inspiring devotion to duty, inflicted great damage on the enemy before leading the planes safely to base, thereby upholding the highest traditions of the United States Naval Service.
