The stone walls were originally to have been inscribed with the names of all Canada's servicemen and women who had died during the First World War; but, without enough space for all 66,000 names, it was later decided to place Books of Remembrance there instead; the books list all Canadian soldiers, airmen, and seamen who died in service of the Crown—whether that of Britain (before 1931) or that of Canada (after 1931)—or allied countries in foreign wars, including the War of 1812, the Nile Expedition and Boer War, the First World War, the Second World War, and the Korean War. The books are displayed in glass cases on seven altars around the chamber, the pages of each book turned at 11 a.m. daily so every name is on display to visitors at least once during each calendar year.
