As a co-pilot of the two-seat F-100F, Gruters was shot down twice. The first shoot down required a parachute water landing less than 1 mile offshore near the North Vietnamese city of Đồng Hới while under fire from the North Vietnamese coastal guns in November 1967. While North Vietnamese boats were prevented from intercepting the downed pilots by strafing U.S. F-4 fighter-bombers, First Lieutenant Gruters and Captain Charles Neel were rescued under heavy fire by two USAF HH-3E Sea King helicopter crews based 60 miles (97 km) away.
Gruters was shot down for the second time on December 20, 1967. He and fellow pilot, Colonel Robert R. Craner were captured and imprisoned in the Hỏa Lò Prison (Hanoi Hilton) among other camps. Upon their initial incarceration, Gruters and Craner cared for Lance Sijan before Sijan succumbed to wounds and torture in January 1968.
Gruters spent 5 years and 3 months as a prisoner of war before his release in 1973. Guy Gruters’ testimony was instrumental in Lance Sijan receiving the Medal of Honor posthumously in 1976.
Guy Gruters’ story was described in the book, “Bury Us Upside Down”, “Into the Mouth of the Cat”, and “Misty: Fast FACS.”
