The third incursion into York occurred a year later, in August 1814. On 6 August 1814, an American naval squadron arrived outside of York's harbour, dispatching to enter the town's harbour in an effort to gauge its defences. After the ship briefly exchanged fire with the improved Fort York, built several hundred metres to the west from its original position, the USS "Lady of the Lake" withdrew and returned to the American squadron outside the harbour. American forces did not attempt a landing during this incursion, although remained outside the town's harbour for the following three days before departing.
