In 1917 the soldiers of the Canadian Corps would prove themselves the equal of any fighting on the Western Front, while on the other side of the wire, the men of the Royal Bavarian Army won a distinguished reputation in combat. Employing the latest weapons and pioneering tactics, the two elite units would clash in three notable encounters: the Canadian storming of Vimy Ridge, the back-and-forth engagement at Fresnoy, and at the sodden, bloody battle of Passchendaele. Featuring carefully chosen archive photographs and specially commissioned artwork, this study assesses these three hard-fought battles in 1917 that involved two of the elite fighting forces of the Western Front, and offers a new take on the evolving nature of infantry combat in World War I.
