I'm trying to find military service for my great uncle, John Stewart (b. 1921 Port Glasgow, Scotland). He relocated to Natal, South Africa in 1936 at the age of 15. I have been told by my mother that he fought in WWII, and that she thinks he may have been a prisoner of war. My question is whether there would be a separate South African army that fought in the war, or if he'd have been part of the British forces. Either way, does anyone have any suggestions on how I might find his military records. Any thoughts or suggestions would be very helpful!
