Thomas Armstrong entered military service in California. He served in the 512th Fighter Squadron, 406th Fighter Group, as a Fighter Pilot during World War II. He was Killed in Action on December 2, 1944, in Mogues, France, aboard P-47D #42-29179 'Nan.'
On that day, 2Lt Armstrong took off from A-80 airfield in Mourmelon-le-Grand, France, on a mission to Saarbruck / Ensdorf / Fraulautern sector in Germany. In-flight, due to poor visibility, the mission was canceled, and they were ordered to land on Rouvres airfield. The four planes of the section having exceeded the airfield of Rouvres, descended below the clouds to turn around, but three planes crashed in the commune of Mogues, including 2Lt Armstrong's plane.
2Lt Armstrong is now buried in the Henri-Chapelle American Cemetery, Hombourg, Belgium.
