This man enlisted with the 18th Battalion at Guelph, Ontario on 26 October 1914, at Guelph, Ontario. HE was an attendant (nurse) at a sanatorium and had 3 years of military experience with the 2nd Royal Munster Fusiliers. He was unmarried and practiced the Anglican faith.
He went to train with the 18th Battalion at London, Ontario and was Struck Off Strength as being medically unfit on 18 February 1915, just prior to the 18th Battalion going overseas.
Undaunted by this experience, he enlisted with the 153rd Battalion at Guelph, Ontario, on 25 February 1915, and was promoted from Private to Sergeant effective 1 March 1916. He was reduced to Corporal at his own request on 23 September 1916.
HE was assigned to the Special Training Depot at Military District No. 2 (Toronto) on 5 April 1917 and served there from 1 April 16 July 1916. He is recorded as being admitted to a Base Hospital in Toronto on 17 May 1917 for otitis media.
He was then transferred to No. 1 Special Service Company on May 29, 1917 and appears to have served with the Headquarters Company.
He was also admitted for this condition at Camp Borden on 24 June 1917, spending 5 days in hospital.
He was discharged at London, Ontario, on 29 October 1917 as being medically unfit.
It was noted that he had a pre-existing condition that prevented him from being eligible for service and that this medical condition had not been aggravated by his service. His conduct was rated as being “Very Good”.
