Agar Adamson (1865 - 1929) joined the Princess Patricia's Canadian Light Infantry in 1914 as captain - even though he was 48 years old and blind in one eye. He served continuously overseas with the PPCLI until the end of the war. Adamson commanded his regiment a number of times owing to casualties among his superiors. In October 1916 he was promoted to lieutenant-colonel and commanding officer of the PPCLI, and successfully and skillfully led his regiment at both Vimy Ridge and Passchendaele. Adamson wrote daily to his wife, Mabel Cawthra, while serving in France and Belgium. These letters are unique in their detail of events, personalities and of day-to-day life at the front. Quoted frequently in the Battlefields section, they give us one of the most thorough accounts in existence of the Canadian soldier's experience in the Great War.
