 The Lieutenant Governor of Upper Canada, Major General Roger Hale Sheaffe, ordered his regulars to retreat to Kingston, but also dispatched Captain Francis Tito LeLièvre (1794-1830) of the Royal Newfoundland Regiment to set fire to "Sir Isaac Brock" to prevent her falling intact into enemy hands.LeLièvre may have been assisted in this task by Thomas Plucknett, as shipyard superintendent was the man most responsible for "Sir Isaac Brock" being in her partially built condition.The Americans were enraged to find that the ship had apparently been set ablaze while negotiations for surrender with the local militia were still taking place.
