In my book, The Father of a Soldier, I have already stated the conditions under which this book of my son's was produced. He was wounded in the end of June, 1917, in the fierce struggle before Lens. He was at once removed to a base-hospital, and later on to a military hospital in London. There was grave danger of amputation of the right arm, but this was happily avoided. As soon as he could use his hand he was commandeered by the Lord High Commissioner of Canada to write an important paper, detailing the history of the Canadian forces in France and Flanders.
