The President of the United States of America takes pleasure in presenting the Silver Star to Second Lieutenant Timothy C. Mulrennan (MCSN: 0-32773), United States Marine Corps, for conspicuous gallantry and intrepidity as Commander of a Provisional Rifle Platoon attached to Battery M, Fourth Battalion, Eleventh Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 4 December 1950. With his platoon assigned the mission of guarding a convoy of trucks and tractor-drawn howitzers during the movement to Hagaru-ri, Second Lieutenant Mulrennan was quick to act when the convoy was stopped by an enemy roadblock and brought under heavy and accurate small arms, machine gun and mortar fire. Moving among his platoon, he repeatedly exposed himself to the heavy barrage to position his men in hasty defense positions and direct their effective fire. Observing many personnel of the convoy assuming positions along the road, he advanced under enemy fire and ordered them to move out and join the defense line, steadfastly refusing to take cover himself until he had built up his defensive positions, set up his machine guns and directed the removal of stalled vehicles that blocked the road. By his daring and forceful leadership, determined fighting spirit and courageous efforts in the face of grave danger, Second Lieutenant Mulrennan served as an inspiration to all members of the convoy and contributed materially to its successful advance forward. His professional ability and conscientious devotion to duty were in keeping with the highest traditions of the United States Naval Service.
