Now in possession of the main city and capital, and further isolating the inner cities of Trois-Rivières and Montreal from France, the rest of the campaign was only a matter of slowly taking control of the land. While the French had a tactical victory in the Battle of Sainte-Foy outside Quebec in 1760, an attempt to lay siege to the city ended in defeat the following month when British ships arrived and forced the French besiegers to retreat. An attempt to resupply the French military was further dashed in the naval Battle of Restigouche, and Pierre de Rigaud, Marquis de Vaudreuil-Cavagnial, New France's last Royal governor, surrendered Montreal on 8 September 1760.
