18th Battalion, Manchester Regiment.
Executed by firing squad 1 December 1916.
Buried in the Bailleulmont Communal Cemetery, France.
Below is an extract from a review of the book - "Blindfold and Alone" by Catheryn Corns and John Hughes-Wilson.
There is a tiny village in deep country near Arras called Bailleulmont. In low ground nearby is the municipal cemetery, with a handful of British war graves attached. The headstone of one of them, that of Private A Ingham of the Manchester Regiment, bears the unique inscription "Shot at Dawn / One of the First to Enlist / A Worthy Son of his Father". Private Ingham and the soldier buried next to him, Private Longshaw, were executed for desertion, probably in this dour little valley, on 1 December 1916. Geoff Dyer wrote movingly of Ingham's fate in his book The Missing of the Somme. He praised the father who, learning the truth about his son's death, chose to celebrate it rather than conceal it. Dyer also saw courage in Ingham's opting out from a brutal war, claiming: "The deserter's grave has become a hero's grave."
Corns and Hughes-Wilson tell us the story behind this double execution. Ingham and Longshaw were discovered on a Swedish ship at Dieppe, having discarded their uniforms and claiming to be American citizens. No army on active service and under appalling pressure - the men were arrested during the Battle of the Somme, in which they had themselves taken part - could overlook such behaviour, especially at a time when many saw prison or penal servitude as an appealing alternative to the hazards of the field..............
