 To redress matters, on 3 September, the United States Navy appointed Commodore Isaac Chauncey, then commanding the New York Navy Yard, to command on the lakes.Although Chauncey was nominally in charge of the naval force on Lake Erie also, he took little part in its construction or operations there but concentrated his attention on Lake Ontario.To supplement "Oneida", he first purchased or commandeered several trading vessels (including some captured Canadian schooners), but he also dispatched thousands of carpenters, shipwrights and so on to Sacket's Harbor to construct proper fighting ships.
