Walter was born in Burton upon Trent in 1886, the son of William and Mary Ann Carson. In 1901 they were at 21 Market Street, Bilston, and by 1911, they were living at 2 Earl Street, Bilston, together with Walter’s siblings William, May Isabella, Leonard, Clara, Edward, Percy, Minnie, Gladys, Victor, Cecil, Elsie and Norman. Walter was a “motorman” with the Tramway Company.
Walter enlisted in the 1st/6th Battalion of the South Staffordshire Regiment (number 2598 and later 240414), apparently one of the first from the Tramway Company to join the Army. He served in France from 5 March 1915. He was invalided home with trench feet, but went on active service for the second time on Christmas Day 1916. He reached the rank of Lance Sergeant. On 20 August 1917, he was killed in action in France. His officer wrote a letter home to his parents, which was quoted in the Express & Star on 15 September 1917:
It is with my deepest sympathy and grief I write to inform you that your son, Sergeant Carson, has been killed. He was not at al conscious, death being instantaneous. Though this is very pool consolation to you it is much better than lingering for any time. He was exceedingly popular with the men, and was ever ready to help any of them at all times, and was much beloved by me, his officer. I tender my deepest sympathy to you in this your time of trouble.”
