David O’Keefe has another bestseller on his hands. Six years after an investigative recasting of a notorious World War II bloodbath in “One Day in August: The Untold Story Behind Canada’s Tragedy At Dieppe”, the award-winning author, broadcaster and military historian is back with an equally engrossing read on another grim chapter in Canadian military history. “Seven Days in Hell: Canada’s Battle for Normandy and the Rise of the Black Watch Snipers” chronicles the days up to and including the July 25, 1944 assault on Verrieres Ridge, where the Montreal-based Black Watch (Royal Highland Regiment) of Canada suffered the worst single-day losses in the regiment’s storied history. David joined us in-studio to talk about the book and the battle. Please click on the link to listen to the segment, and note that David will be a guest of the Hudson Historial Society November 17.
