I wonder whether any members of this forum may be able to help?
I am one of John Coste's great nephews. John sadly died in 1988 and his wife Yvonne in 2001. I would all be fascinated to know more about his war. I know that he took part in the Dieppe raid and was awarded the DSC and I know that, towards the end of the war, he commanded MGB 312.
If anyone has any more details of John's career, I would be delighted and grateful to hear them.
