“We turn out of our hammocks at 6.30am and lash up and stow in the usual way,” a Royal Navy sailor named Frank Baker wrote in his diary on December 6, 1917. “We fall in on the upper deck at 7am and disperse to cleaning stations, busying ourselves scrubbing decks etc. until 8am when we ‘cease fire' for breakfast.” Baker was pulling wartime duty as a ship inspector in the harbor of Halifax, Nova Scotia, on the lookout for spies, contraband and saboteurs.
But there were no ships to be inspected that day, so after breakfast he and his crewmates aboard HMCS Acadia went back to their cleaning stations. “We...had just drawn soap and powder and the necessary utensils for cleaning paint work,” he wrote, “when the most awful explosion I ever heard or want to hear again occurred.”
