Lieutenant Grant Davidson Mowat was born in Meaford, Ontario, on June 10, 1894, to parents Alexander and Annie Elizabeth Mowat. The family later moved to Peterborough, Ont. Following his graduation from Peterborough Normal School, Mowat worked for several years as a schoolteacher. Shortly before his enlistment he had been accepted as a law student at Osgoode Hall in Toronto, Ont.

He was commissioned as an officer with the rank of Captain in February of 1916, and shipped overseas aboard the SS Empress of Britain the following July to join the 93rd Battalion in England. Mowat’s military records show that while stationed in England in April of 1917 he requested to revert to the rank of Lieutenant in order to be posted to France; Lt. Mowat joined the 21st Bn. in France on May 1, 1917.

Mowat was killed in action on August 15, 1917, during the Battle for Hill 70 near Lens. Mowat’s remains were not identified at the time of his death and as such his name was inscribed on the Vimy Memorial. In the 1990s Mowat’s gravesite was identified; he had been buried as an unknown soldier in the Cabaret-Rouge British Cemetery, Pas de Calais, France. A new headstone identifying Mowat’s gravesite was made at that time.

Content notes:
Most of the collection’s letters were written by Mowat to his parents while he was stationed overseas in England and France. Often mentioned is his cousin “Mina” whose letters of the same time period can be found in the Nursing Sister Wilhelmina Mowat Collection.
On rank discrepancies: Mowat’s final rank appears in many records and sources as Captain, however his service record indicates his final rank as Lieutenant; this rank is used for his records with Library and Archives Canada and as such it is what has been used in his collection here.
