Ackroyd was the son of Harris Hunter and Sarah Ann Riley, of 18, Bartle Lane, Great Horton. Both his parents were born in Queensbury and at the time of the 1911 census they had been married for 20 years. Ackroyd like his father, was a textile worker.
He served in the 10th Battalion, Duke of Wellington’s (West Riding Regiment) and was aged 20 when he was killed in action on 30th July 1916. At the time of Ackroyd’s death the Battalion war diary states that they were occupying the front-line trenches that ran through Contalmaison (Somme). On the 29th July they suffered heavy shelling and were called into action. The war diary states: we sustained somewhat serve casualties. These were: 33 killed, 128 injured, 13 suffering shell shock and 31 missing.
The Battalion were relieved overnight on 30th July moving back into the reserve trenches. The diary does not record any casualties for 30th July, so it is possible that Ackroyd was killed on 29th July. He may have been one of the 31 recorded missing as he has no known grave and his name is on the THIEPVAL MEMORIAL (Pier and Face 6 A and 6 B). He is also named on the family grave within Queensbury Churchyard.
