Wolfe arrived outside Quebec on 28 June. For much of the rest of the summer, he probed the defences of the city, trying to find a way through. Montcalm constantly frustrated him, shifting his own troops about in response. The cat-and-mouse game between the two generals reached a climax towards the end of the summer. If Wolfe could not capture the city he would likely be forced to withdraw in the face of the hostile Canadian winter. An attempt to land on the Montmorency was beaten back at the Battle of Beauport, and almost proved disastrous. Wolfe now searched for another place to land and make his attack. On 12 September the British learned of a convenient landing spot, and Wolfe moved his army there at night. The following day the Battle of the Plains of Abraham took place. It proved to be a decisive British victory, though one in which both Wolfe and Montcalm were killed. The British then took over the city.
