Erik Sass is covering the events of the war exactly 100 years after they happened. This is the 295th installment in the series.
December 6, 1917: Horror in Halifax
In addition to all the deliberate destruction, the First World War generated enormous collateral damage in the form of accidents, usually resulting from the movement of large numbers of people and dangerous material in unfamiliar environments—plus a lack of safety precautions that would be considered truly shocking by modern standards.
One of the worst accidents of the entire war occurred far from the European war zone, in Halifax, Nova Scotia, an important stopover for cargo ships carrying munitions from factories in Canada and the United States to Europe.
Around 8:45 a.m. on December 6, 1917, a French cargo ship packed with explosives and high-octane fuel, the Mont-Blanc, collided with the Imo, a Norwegian ship chartered to carry relief supplies to Belgium in Halifax Harbor (below, the Imo after the blast). The collision started a fire aboard the Mont-Blanc, which quickly grew out of control. Twenty minutes later the deadly cargo ignited, unleashing a blast of phenomenal power, estimated to be equivalent to around 2.9 kilotons, or about a fifth of the atomic bomb that destroyed Hiroshima.
The explosion completely destroyed Halifax’s Richmond district, killing approximately 2000 people and injuring 9000 more. The strength of the blast was illustrated by the fact that a 3-ton anchor was thrown a distance of 2 miles, while a sailor’s decapitated head is said to have smashed church windows 1.5 miles away. A tidal wave created by the explosion killed every member of a community of Mi’kmaq people, a local First Nations tribe.
Barbara Orr recalled growing panic as the fire spread aboard the Mont-Blanc in plain view of people on shore who were helpless to stop it, followed by the cataclysm, then darkness and a huge wall of water:
It was so still, so calm, and this terrible, awful column of smoke went up, and then balls of fire would roll up through it. Then they burst—but there was no sound. It was the strangest thing. I stood spellbound in the middle of this field, and then thought, oh, something awful is going to happen. Suddenly the explosion went off. … I was thinking that I was going down in deep holes all the time. Somebody said that would be almost like an unconsciousness … There was this tidal wave—it’s said that you could see the bottom of the harbor. Well, this tidal wave … took a lot of people back into the harbor on the way down … but since I was smaller and lighter, I was caught in the tidal wave and the force of the explosion blew me the rest of the way.
Another victim, Ethel Mitchel, was at home when the blast destroyed most of the structure:
When mother went down she was on the stairs when the explosion occurred. The cellar stairs were below the stairs going up to our rooms. The stairs, carpet and all went to the basement with mother on top of them. She was horribly cut. All I know is that this deafening roar occurred and the windows, both the windows went out towards the door on each side of me, and my cat was at the foot of the bed, killed. And yet I was not touched. I was totally unhurt. I was in that only corner of the house that was intact. Now here is the amazing thing. The stairs were taken completely away. How did I get down from that room to the next floor? I had glass in the soles of my feet, from running across the room. If I had jumped I would have gone right to the basement. And nobody knows yet how I got down. But I was found later sitting on a biscuit box way over on a corner, at the grocery store. Yes, and I had a man’s overcoat on, it didn’t belong to us, I don't know where I got it, and a man’s boots on, and nobody knows where I got them. Somebody recognized me, and took me back home.
The disaster—still considered one of the worst maritime shipping accidents ever—gave ordinary people a taste of the horror of war, and soldiers a disturbing preview. Two weeks after the explosion, Briggs K. Adams, an American soldier who stopped in Halifax en route to Europe, wrote home on December 22, 1917:
We all read about the disaster at Halifax, but you had to see it to form any conception of how terrible it must have been. At the farther distances, just windows and chimneys were broken; nearer, roofs and walls were caved in, and then in the immediate area, a whole hillside was stripped as flat as if it had been raked, not even heaps of wreckage—everything level. It must have been incredibly terrific.
The Canadian government hurried to first deliver tents and then build temporary housing for thousands of residents left homeless in the middle of winter, while concerned citizens across the U.S. and Canada donated huge amounts of food, clothing, and other necessities for the victims. However, major reconstruction efforts would continue until 1922, and a number of factories destroyed in the disaster were never rebuilt, leaving many unemployed.
Today the disaster is commemorated by the Halifax Explosion Memorial Bell Tower (above). The memorial recreates the appearance of a wrecked house; the bells were donated by Orr, who lost her entire family in the blast, including her parents and five siblings.
