At approximately 8:45 a.m. on 6 December 1917, the Belgian Relief vessel IMO struck the munitions-laden freighter Mont-Blanc in Halifax Harbour. The Mont-Blanc exploded in a devastating 2.9 kiloton blast, which killed 2,000 people and injured 9,000. More than 6,000 people were made homeless, and an additional 12,000 were left without shelter.
