 In December, 1917, Halifax, Nova Scotia, was the hub of the Dominion of Canada. World War I had brought activity and prosperity to the port. Convoys of ships loaded with war supplies of food, munitions and troops gathered in Bedford Basin ready for the voyage to Europe with heavily-armed warships as escorts. Neutral vessels anchored in the harbour, their crews forbidden to land for fear any might supply information to the enemy. New railway lines and terminals were almost completed, made necessary to handle the extra pressure of traffic. The population was swollen with troops, some awaiting embarkation for Europe, some garrisoned there, their families, and people who had come to benefit from the plentiful employment. At 7.30 a.m. on December 6, the French ship Mont Blanc left her anchorage outside the mouth of the harbour to join a convoy gathering in Bedford Basin. She was loaded with 2,300 tons of wet and dry picric acid, 200 tons of TNT, 10 tons of gun cotton and 35 tons of benzol: a highly explosive mixture. At the same time the Norwegian vessel Imo, in ballast, set off from the Basin bound for New York to pick up a cargo of relief supplies for Belgium. At the entrance to the Narrows, after a series of ill-judged manoeuvres, the Imo struck the Mont Blanc on the bow. Although the collision was not severe, fire immediately broke out on board the Mont Blanc. The captain, pilot and crew, expecting the ship to blow up immediately, launched the lifeboats and took refuge on the Dartmouth shore.
The ship burned for twenty minutes, drifting until it rested against Pier 6, in the Richmond district, the busy, industrial north end of Halifax. The spectacle was thrilling, and drew crowds of spectators, unaware of the danger. |

 Just before 9.05 a.m., the Mont Blanc exploded. Not one piece of her remained beside the dock where she had finished her voyage. Fragments rained on the surrounding area, crashing through buildings with enough force to embed them where they landed.Churches, houses, schools, factories, docks and ships were destroyed in the swath of the blast. Children who had stopped on their way to school, workmen lining the windows, families in their homes, sailors in their ships, died instantly. Injuries were frightful, blindness from the splintering glass adding to the shock and bewilderment.
The captain, pilot and five Imo crew members were killed. All from the Mont Blanc survived, apart from one man who later died from his wounds. |

Mercifully, rescue began quickly, with the thousands of well-disciplined troops and naval strength available. City officials speedily arranged for volunteer help: relief committees had been formed by the afternoon of the disaster. Word went out to the surrounding areas and they responded with commendable speed. Hospitals and places of shelter were soon overcrowded. All possible buildingseven ships in the harbourwere commandeered, and some of the injured and homeless sent by rail to other cities.
News of the disaster reached Boston the same morning. That very night a train loaded with supplies, together with medical personnel and members of the Public Safety Committee, left for Halifax. Help poured in from all over Canada and many parts of the world, with the continuing generosity of Massachusetts unforgettable. Each Christmas the huge tree that glitters in Prudential Plaza in Boston is a thank-you gift from the people of Nova Scotia. |

 1,630 homes were completely destroyed, many by fires that quickly spread following the explosion; 12,000 houses were damaged; 6,000 people were left without shelter. Hardly a pane of glass in Halifax and Dartmouth was left intact. The death toll rose to just over 1,900. About 250 bodies were never identified; many victims were never found. Twenty-five limbs had to be amputated; more than 250 eyes had to be removed; 37 people were left completely blind. Hospitals treated well over 4,000 cases, and private doctors hundreds more. The Dominion Government appointed the Halifax Relief Commission on January 22, 1918. It handled pensions, claims for loss and damage, rehousing and the rehabilitation of explosion victims. It was disbanded only in June, 1976. Pensions are now paid by the Department of Veterans Affairs. |

As a result of the tragedy certain benefits accrued to the city. Medical treatment, social welfare, public health and hospital facilities increased and improved. Regulations relating to the harbour were tightened, making it as safe as human errors of judgment would permit. The Hydrostone development, built as relief housing, still stands, an early example of a very high standard of urban development.
The official enquiry opened less than a week after the explosion. The captain and pilot of the Mont Blanc and the naval commanding officer were charged with manslaughter and released on bail. Later the charges were dropped, because gross negligence causing death could not be proved against any one of them. In the Nova Scotia District of the Exchequer Court of Canada in April, 1918, the Mont Blanc was declared solely to blame for the disaster. In May, 1919, on appeal to the Supreme Court of Canada, both ships were judged equally at fault. The Privy Council in London, at that time the ultimate authority, agreed with the Supreme Court's verdict. Thus no blame was ever laid in the largest man-made explosion until the atomic age, when its effects were studied by Oppenheimer in calculating the strength of the bombs for Hiroshima and Nagasaki.

Many gravestones, artifacts and monuments in the cities of Halifax and Dartmouth are reminders of the explosion. The most impressive is the Memorial Bell Tower on Fort Needham, overlooking the explosion site. Hanging there is a carillon of bells, donated in 1920 to the United Memorial Church, which was built to replace two churches destroyed in the explosion. The presentation was made by a young girl who had lost her entire family in the blast, her mother, father and four brothers and sisters. At 9 a.m. on December 6, every year, a service is held there in memory of the victims of the Explosion. The bells ring out and can be heard across the Narrows in north Dartmouth, all around Fort Needham, and in the areas devastated by the Halifax Explosion of 1917.  |
