Desmond T. Doss (1919-2006) was the first conscientious objector to receive the Congressional Medal of Honor. Because of his religious beliefs, he refused to carry weapons and was thus assigned to the army's Medical Corp as a corpsman. His repeated acts of valor during the Battle of Okinawa,where he ignored intense enemy fire to keep treating and rescuing wounded comrades, led to his serious wounding on May 21, 1945. Today, he rests at the National Cemetery in Chattanooga, Tennessee.
