A French munitions ship and a Norwegian steamer collided in Halifax harbour in December 1917, and the blast that followed remains the largest human-made explosion before the atomic bomb. Within six days, a formal inquiry opened — and within two months it placed nearly all the blame on one harbour pilot.
Wreck Commissioner Arthur Drysdale's inquiry found Mont-Blanc's pilot and captain responsible for the collision that triggered the disaster, and all three men involved, including a naval examining officer, were arrested on manslaughter charges. None was ever convicted. Two higher courts — the Supreme Court of Canada in 1919 and the Judicial Committee of the Privy Council in 1920 — later reviewed the same evidence and found both ships equally at fault, citing details about the Norwegian ship's speed and position that Drysdale's inquiry had barely examined. Pilot Francis Mackey was legally cleared, but Canada's government refused for years to restore the license that let him work. This episode traces how the first verdict was reached, where it diverged from the courts that followed, and the question no inquiry has ever fully answered: how blame for the collision was actually shared.
