The President of the United States of America takes pride in presenting the Navy Cross (Posthumously) to Dentalman Thomas Andrew Christensen, Jr. (NSN: 4167756), United States Navy, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as a Corpsman attached to the First Amphibian Tractor Battalion, FIRST Marine Division (Reinforced), in action against enemy aggressor forces at Kowan, Korea on 6 November 1950. Dentalman Christensen was serving as a Corpsman with a railroad train guard when the train was ambushed by a strong enemy force while stopped in Kowan, Korea. The train was subjected to heavy enemy fire and numerous casualties were suffered. With absolute disregard for his own personal safety, he fearlessly exposed himself to enemy fire to treat wounded Marines and move them to positions of cover. When the enemy attacked the train the second time, he was mortally wounded by enemy fire and gallantly gave his life for his country. His aggressive actions, while subjected to intense enemy fire were an inspiration to all who observed him. Dentalman Christensen’s display of outstanding courage and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
