My great grandfather fought in WW1, enlisted from Nelson Lancashire in 1916, and was originally a member of the East Yorkshire regiment, but when he was discharged (from Queen Marys convalescent hospital in 1919) it was from 2nd Durham Light Infantry. I have his discharge papers and have seen his medals, but know nothing else as he never spoke about it - not even how he was injured.
Does anyone know if there is any way of finding when and where he fought, why he changed battalion and when and where he was injured? I have tried searching online for his record but without luck.
Many thanks in advance of any help offered
