More than 1,650 people were killed at Halifax when the Norwegian ship Imo plowed into the French munitions ship Mont Blanc. Mont Blanc was loaded with 4,000 tons of TNT, 2,300 tons of picric acid, 61 tons of other explosives and a deck of highly flammable benzene, which ignited and touched off an explosion. In addition to those who were killed, 1,028 were injured. A tidal wave caused by the explosion washed much of the city out to sea.
