The silence after the blast: How the Halifax Explosion was nearly forgotten
HALIFAX — A boy presses his small face up to a cold window pane. It’s an early winter morning, and two ships in Halifax harbour are exchanging a cacophony of horn blasts.
Vessels use these loud whistles as they pass, the boy’s mom explains.
But today, Dec. 6, 1917, they do not pass.
The Norwegian relief vessel, the SS Imo, collides with a French munitions ship laden with explosives, the SS Mont Blanc. For 19-1/2 minutes, a dazzling display of fireworks captivates onlookers as the Mont Blanc drifts and burns.
