Canadians entered World War One viewing armed conflict as a majestic affair. What they discovered was that life in the trenches was grim and the slaughter unimaginable. With victory hanging in the balance, officials at home began propping up notions of the conflict-and of the enemy-that sometimes had little to do with facts.
It has a rather specific focus, as the title suggests, but goes into a great deal of detail about the efforts that were made (both at home and abroad) to leverage a nascent "Canadian identity" in the bid to encourage greater recruitment and sway public opinion. An excellent work, and pretty much the book on its particular subject. I'll have more to say on WWI propaganda in general in a section below.
