I am trying to help my ex wife in researching her grandfather's war time service. She has recently come into possession of his war medals after the death of her mother. His Defence Medal has a bronze Oak Leaf on the ribbon. After a little research i have found that it was for being mentioned in dispatches. He is also mentioned in the London Gazette of the 21st Oct 1941. According to some of the paper work she has, it says he was in the Royal Engineers (she also has his cap badge) and was Mentioned in Dispatches because of his UXB work during / after the May 10 - 11th air raids on London. How can we find out more information as to what exactly he did and why he was mentioned in dispatches? Thanks for each and every reply i may receive as any help you may pass on is far more information than we have now.
