The mill was destroyed on December 6 , 1917 by an accidental explosion of a munitions ship in Halifax Harbour known as the Halifax Explosion . Although almost a mile from the explosion and out-of-sight of the harbour , the mill was devastated by the explosion . The shock wave caused a partial collapse of the concrete floors of the building and started a fire which consumed the building and killed many of the workers
