Dear all, good luck with your searches. My maternal grandfather Joseph Moses, East Yorks regt was awarded the MM. I started with his medal card, then London Gazette, then local papers and found no explanation.
Took a trip to Kew last year spent two days looking through the war diaries and my Dad's naval records for WW2. The war diaries are hard work, but worth it for understanding something of what they went through. Only mention I found was that he had been awarded the MM but no comment as to why.
