The wife's uncle recently passed away and had never been keen on talking about what he did in the war. In the last few years he told my son more about his exploits than most of the family although they did have some ideas about what he had been up to.
He served in the Marines most of the time but was allocated special duties. He did tell me about the time prior to D-Day when he was assigned to body guard a boffin as they were landed on the French beaches to take a close look at the German radar and nearly got caught, and that how when he came back with the boffin in civvies he was spat at as an objector.
He recounted to my son once that immediately after the invasion he had his picture taken on standing on a V2 to 'give it some scale' by the same Boffin.
I'm sure he did much more but now we will never find out.
