Career
McGill joined the Army from Ada, Oklahoma in November 1940, and by March 4, 1944 was serving as a Sergeant in Troop G, 5th Cavalry Regiment, 1st Cavalry Division. During an enemy attack on that day, on Los Negros in the Admiralty Islands, he held his ground against the numerically superior force. After ordering the only other un-wounded man in his squad to retreat, he continued to hold his position alone and eventually engaged the enemy in hand to hand combat until he was killed.
McGill, aged 29 at his death, was buried at Knoxville National Cemetery in his birth city of Knoxville, Tennessee.
A section of Interstate 40 in Knoxville, Tennessee is named " McGill Memorial Highway".
