A number of ships have “gone missing” on Lake Superior. The Griffon, Bannockburn, Henry Steinbrenner, and Merchant are only some of the lost fleet still lying in the Big Lake’s dark depths. Among these mysteries are the French Navy minesweepers Inkerman and Cerisoles. Built in Port Arthur, Ontario, the pair departed on November 23, 1918 bound for Montreal, before final delivery to France. Somewhere in Lake Superior they disappeared. Searches failed to find the missing warships. No confirmed human remains were ever recovered and the sparse flotsam gave no clues. Accusations of poor construction, shoddy seamanship and collision followed but real evidence was illusionary. French Navy investigations were equally lacking in answers. In this episode, maritime historian Fred Stonehouse shares his research into one of Lake Superior’s greatest unsolved mysteries.
