When the 1901 Census was taken, the Robinsons were living at Lyme Grove, Romiley but had moved to "Oakleigh", Offerton Road, Torkington by 1914. Walter was the second child of Samuel and Jane. He had an older brother, Harold and a younger sister, Alice.
Nothing more is known about his life other than he had been born in Ashton under Lyne. Walter's original service number, 3229, suggests that he enlisted around the middle of 1915 and probably went on active service at the beginning of 1916 when the Battalion was withdrawn from the failed campaign at Gallipoli.
On the day Walter is reported to have been killed, the Battalion was in camp at Le Preol. The men were taking baths and, generally, preparing for another tour of duty in the front line, starting the next day. They were well away from danger.
They left camp on the 15th and took over a section of trenches from the 1/8th Battalion that is only described in the unit's War diary as being "off the Cambrin road". Walter's Company, "A", and "C" Company were in the actual front line with "B" and "D" in support trenches a little way to the rear. The Diary records that there was little hostile activity from the Germans but it was later reported in the newspapers that Walter had been killed by an exploding shell and it seems more likely that it was on the 15th, rather than the 14th. It was the responsibility of a junior officer to maintain the War Diary but it was up to each individual what they included and what they excluded. Whilst it more usual for casualties to be noted on a daily basis, none are recorded by the officer maintaining the Diary during this tour in the trenches, so it is now impossible to establish what might have happened to Walter.
Harold Robinson is understood to have served in the Cheshire Regiment and survived the War.
