Niagara frontier, 1813

An American force surrendered on 24 June to a smaller British force due to advance warning by Laura Secord at the Battle of Beaver Dams, marking the end of the American offensive into Upper Canada. British Major General Francis de Rottenburg did not have the strength to retake Fort George, so he instituted a blockade, hoping to starve the Americans into surrender. Meanwhile, Commodore James Lucas Yeo had taken charge of the British ships on the lake and mounted a counterattack, which the Americans repulsed at the Battle of Sackett's Harbor. Thereafter, Chauncey and Yeo's squadrons fought two indecisive actions, off the Niagara on 7 August and at Burlington Bay on 28 September. Neither commander was prepared to take major risks to gain a complete victory.
