N.B. the 7th Battalion Gloucester Regiment, part of the Mediterranean Expeditionary Force, served in Gallipoli from July 1915 to January 1916. This may well be where he served (his medal card merely says ‘Balkans’). They appear to have been amongst the last to be evacuated, as casualties are listed on 8th Jan 1916, with the evacuation complete by the 9th.
There is no obvious reason for him being returned from France in January 1917, but his daughter Joan believed he had been gassed, and that would explain why he was eventually discharged.
Also note that he obviously managed to get home to London when granted leave in May 1917, son Sterndale Jack was born in Feb 1918.
