Thanks Jim, I will check that out. As he wrote on the back of the Thrid Class Certificate about his exploits on the 126th August 1914 up to October that would suggest he got that certificate before coming to France. That may have played a part in his transfer to the RE to be a dispatch rider. He may have had training in England as he already had the training for mounted infantry in 1912. Everyone here has helped me understand both my grandfather and also why my Dad joined the territorial army and served for 11 years reaching sargent.
