Geoffrey Hayes and most of the youngish military history professors in Canada have put together Vimy Ridge: A Canadian Re-appraisal, edited by Hayes and others, and just coming out from Wilfred Laurier UP.
Haven't read it, and not sure if it's a real revision or just "Let's try to dull this down a bit." In the same way the RCMP became what someone called "the world's only souvenir police force," Vimy sometimes threatens to become more symbol than battle. Over the years I've sometimes found our academic military historians a bit too "official," their writing a bit too identified with the military perspective. If this signals a more risk-taking attitude, I'm all for it.
