Canon Frederick George Scott was the padre of the 1st Division of the Canadian Corps and the confidant, friend and spiritual guide to many generals, officers and enlisted men during the war. When he returned from the war he continued to be revered by thousands. In 1934 he published The Great War as I Saw It, a memoir of his experiences. He is also known as a poet of religious, inspirational and patriotic poetry. During the Quebec Conference, held in the summer of 1943, Canon Scott was invited by Churchill and Roosevelt to a private meeting where he read some of this poetry.
