Resentment of the old settlers grew to rebellion, with Oxford's elected member in the legislative assembly, Dr. Charles Duncombe, taking on the role as leader of an uprising in December 1837. In the aftermath, Duncombe was driven into exile, and one of the Woodstock retired Royal Navy veterans, Captain Andrew Drew (Vansittart's right-hand man), created an international incident that is still studied by legal scholars, when he led a raid into the United States to seize and burn a paddlewheel steamer being used in the Niagara River by the exiled rebels, leaving it to drift over Niagara Falls.
