With my WW1 hat on, have looked at some basic sources on ancestry & the Long Long TraiI website to see what part of the RFA Matthew HOOD no 14671 was in & how he could have been injured. I have PM'd the results to you Hoody as this is taking things away from WW2. But it is probable that he was in 92nd Brigade RFA, part of 20th Light Division of the New Army, formed in Sept 1914. They went to France July 1915. His service number is only one different from a soldier who also went to France with the brigade on 22 July 1915 & this man joined up in Sept 1914. All of this gave no clue as to the post WW1 service of Matthew HOOD.
