On December 6, 2019, the twin cities of Halifax and Dartmouth will mark a devastating event in their histories. On that morning in 1917, a cataclysmic event occurred, leaving large sections of the two cities in ruins. It would go down in history as the largest man-made explosion of its time and would remain there until the atomic bomb in 1945.
The SS Imo, a Norwegian vessel chartered to transport relief supplies overseas, struck the SS Mont-Blanc, a French cargo ship en route from New York to France. Loaded with wartime explosives, the Mont-Blanc caught fire. It raged out of control and ignited the cargo.
