John Sinclair was born on 24 June 1888. He was native to Newton, Tattenhall, and was baptised in Tattenhall. His mother was Emma Sinclair (who subsequently married William Henry Bager in the last quarter of 1894; John being 6 years old). They subsequently moved to Alpraham Green, Cheshire.
John Sinclair joined the 10th Battalion of the Cheshire Regiment. He attested into the army on 29 February 1916 and gave his occupation as skilled labourer. On the day he joined the army he was given an armband to wear to identify that he was no longer a civilian. John was 5ft 5.5ins tall and weighed 128lbs. He spent the early spring and summer of 1916 in training before being posted to the 10th Battalion on 23 July. He was killed just 28 days later when the Battalion was in dugouts near Authuille. He died on 19 August 1916 (documents on the Commonwealth War Graves site identify 2 dates of death i.e. 19 August and 20 August). He was 28 years old.
Private John Sinclair is remembered on the Tattenhall War Memorial and at Blighty Valley Cemetery, Authuille Wood, Somme, France. The area is located in a deep valley and since the area contained a railway, it was inevitably a dangerous location during the Battle of the Somme.
