Hi WW2talk I mentioned him before, but I have more info. My Grandad, Sidney A MacKinney, Sapper, 1912831, served in Iceland in May 1940. He was in 711 middx. County Council Company, general construction company. Royal engineers. His Co. Was Major CJ Teychenne. In 1940, he sent a book about Iceland to a Mr Morgan, of middx co. Co. Who also served in Iceland, With a covering letter explaining what the Company were doing in Iceland and asking for news from middlesex. It's held in the London metropolitan archive, but as I am in ireland, it's not accessible to me at this time. Would anyone have any more info? About the whole operation and my Grandads role? Thank you in advance Kerry
