This man was a baggage-man with the Grand Trunk Railway when he enlisted with the 186th Overseas Battalion at Chatham, Ontario on February 25, 1916, and was assigned reg. no. 880530. Serving with this battalion he trained with it until the 186th went overseas in March 1917. He was assigned to the 4th Canadian Reserve Battalion on arrival in Bramshott, England on April 4, 1917.
On September 5, 1917, he proceeded overseas to his new assignment with the 18th Battalion arriving on November 20, 1917.
He served with the Battalion until April 6, 1918, when he began to suffer from acute indigestion. This condition warranted treatment in England and he returned to England for treatment and he did not return to active service.
He was discharged on December 10, 1919, after a long treatment in Toronto.
