My grandfather received the Military Medal for bravery in 1918. My mother (now aged 82) would love to know what he did to get this honour. I have quite a lot of information about him but the original citation he would have received has been lost. He never talked about it. My research so far on-line suggests it may be difficult to find out the reason. Can anyone help?
He was James Fraser, d.o.b. 25.07.1899, born in Inverness, Scotland. He joined up in 1916 with the 6th battalion of the Seaforth Highlanders. He was a Private, his number was S/25208. He earned his Military Medal apparently on 9.04.1918. From my research on-line it appears this could have been the battle of Estaires. He survived and was taken prisoner of war until the end of the war. I have found the announcement of his MM in the London Gazette 7.10.1918 but this gives no information of what he did.
I have read about the Morayshire Roll of Honour but this seems to be a rare document (£600 to buy on Amazon!!) and I wonder whether this would give any information about him personally. I have also seen a reference to '6th Battalion Seaforth Highlanders Campaign Reminiscences' by Capt R t Peel & Capt A H MacDonald. Also 'The Spirit of the Troops is Excellent: 6th Battalion Seaforth Highlanders in the Great War' by Derek Bird. Would these be useful? I don't want to go to the expense of buying books unnecessarily.
Is it likely my grandfather would have appeared in a newspaper report in Scotland at the time and if so which newspaper would have covered Inverness?   
I hope someone has a bright idea about what I can do!
