With his unit, he participated in the battles of the Naktong River perimeter, Wolmi-Inchon, Seoul and Wonsan; and in the Marine advance north toward the Yalu River. He was subsequently awarded the Army Distinguished Service Cross for extraordinary heroism in the 1st Division's historic breakout from the Chosin Reservoir area to the sea at Hamhung, and two days later took part in the action which earned him his second Navy Cross. Shortly afterward, with his regiment committed to fighting on the Central Korean front, he was advanced to the rank of colonel, in January 1951.
