Canadian Historian David O'Keefe has written a new book about the exploits of his former regiment - the Black Watch (Royal Highland Regiment) of Canada - during the Normandy Campaign in WWII. "Seven Days in Hell: Canada's Battle for Normandy and the Rise of the Black Watch Snipers," chronicles the bloody battle for Verrières Ridge in 1944, which saw 300 Black Watch soldiers pinned down as the result of strategic blunders, leading to 315 of its 325 soldiers being killed, wounded, or captured. As the Canadians came under attack from elite SS units, O'Keefe says "station, rank, race and religion mattered little, and only character won the day." O'Keefe joins Gormley now to discuss the book and one of Canada's most heart-pounding military stories.
