Guy Marsh Jr. was born on February 25, 1920, in Maine. He was the son of Guy C. Marsh and Blanche M. Nichols Marsh. Before entering military service in January 1943, he attended Bangor High School, completed a machinist course at the N.Y.A. school in Dexter, and worked for the Chance Vought Aircraft division of the Sikorsky Aircraft Corporation in Connecticut. During his service, he was stationed at several military bases in the United States before being deployed overseas. He served in the 760th Bomber Squadron, 460th Bomber Group, Heavy, as a Technical Sergeant and Radio Operator of B-24 #42-51160 during World War II.

On June 30, 1944, the aircraft based at Spinazzola Airfield near Foggia, Italy, was shot down during a bombing mission to the South Synthetic Oil Refinery at Blechhammer, Germany. While flying near Lake Balaton, Hungary, the bomber formation encountered heavy enemy fighter opposition and poor weather conditions over the Balaton region, which forced the formation to alter its course and left it vulnerable to attack. During the engagement, the aircraft was hit by gunfire from a German Messerschmitt Me 410A of ZG 76/2. Hungarian fighter activity in the area was also reported during the battle. The Liberator crashed near Szigliget at approximately 10:50 AM. Five of the ten crew members were killed in the crash, while the remaining five successfully bailed out, were captured as prisoners of war, and were later released in 1945.

TSgt Marsh was Killed in Action and is now buried in the Lorraine American Cemetery and Memorial, Saint-Avold, Département de la Moselle, Lorraine, France.
