The battle of Vimy Ridge in April 1917 saw Canadian troops storm a 14-kilometer long escarpment that was believed to be impregnable. This was the first time in Canada's history that a corps-sized formation fought together as a unit under its own leadership. Canadian troops persevered under heavy fire to take the ridge. The battle has since been much celebrated in Canada, as historians and descendants seek to explain the huge losses that military and political leaders accepted in a war that produced few gains for any nation. Tom Douglas recounts the events of this battle, and his narrative is accompanied by over 50 photos, drawings, and paintings by Canadian war artists.
