The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Corporal Hubert David Mark (MCSN: 655454), United States Marine Corps, for conspicuous gallantry and intrepidity while serving as a Radio Operator and Jeep Driver in Headquarters and Service Company, First Marines, FIRST Marine Division (Reinforced), in action against enemy aggressor forces in Korea on 29 November 1950. Assigned the mission of driving to an area where a large motor convoy was being attacked by a numerically superior hostile force and to radio information on the situation back to Regimental Headquarters, Corporal Mark carried out his task with great speed and efficiency. Ambushed by an enemy patrol and wounded while returning to headquarters, he took cover beside his jeep and delivered pistol fire on the enemy until his ammunition was exhausted. Despite the hostile fire, he obtained a rifle from the jeep and placed accurate and effective fire on the enemy, aiding the other members of the jeep in seeking covered positions. Although mortally wounded by hostile machine gun fire, he continued to bring fire to bear upon the enemy until he lost consciousness. By his courageous actions, he served to inspire all who observed him and contributed materially to the subsequent repulse of the hostile attack. His outstanding courage, initiative and aggressive fighting spirit reflect the highest credit upon Corporal Mark and were in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
