Walter Sargeant was born at Pickworth on 8 April 1887, the son of William Sargeant. He was married, and lived with his wife and young daughter at Ludbrooke in Lincolnshire. He was a policeman in Lincolnshire before the war and joined the Army from Ludbrooke on 18 August 1917. He enlisted as a motorcyclist in the Royal Engineers, but was later transferred into a special company. Walter went out to France on 1 November 1914, and was killed by a trench mortar bomb going off accidentally on 18 March 1918. George Phillips wrote: "In a letter of sympathy to the widow, Pioneer Sargeant's officer spoke very highly of his merits as a soldier and a comrade. The deceased's brother Frank Sargeant, of the Machine Gun Corps was awarded the Military Medal for gallantry in Egypt." Walter was 30 years old and is buried in Chapelle British Cemetery, grave II.B.19, and is remembered on Pickworth's war memorial.
