104 years ago, 6 December 1917, Belgian relief vessel Imo was leaving Halifax Harbour on its way to New York. French munitions ship Mont Blanc was entering the harbour to wait for a convoy. Because of a miscommunication, the two ships collided at 8:45 am. The munitions ship was carrying picric acid, gun cotton, and TNT. Her top deck carried benzol which spilled and caught fire. The captain and crew of the Mont Blanc abandoned ship in lifeboats for the Dartmouth shore, allowing the ship to drift towards Pier 6. The Mont Blanc rammed Pier 6, setting its wood pilings on fire. Just after 9:04 am, the Mont-Blanc exploded. The blast and the resulting tsunami, which surged approximately 18 metres above the high-water mark, pressed some three blocks into the city. More than 1,600 buildings were destroyed by the wave, and debris was scattered for several miles. Nearly 2,000 people died, another 9,000 were maimed or blinded, and more than 25,000 were left without adequate shelter.


A Seth Thomas brass ships clock, from the Mont Blanc, was thrown approximately two and a half km southeast and landed behind the Garrison Military Hospital on Cogswell St. It ceased working at the moment of its destruction.

The clock was found by Pte Charles Hefford, a patient recovering from a leg amputation. He was at the rear (southeast side) of the hospital at the time of explosion. The north end was badly damaged from the blast. He managed to make his way out of the south end and found the clock.
