All of Britain's campaigns against New France succeeded in 1759, part of what became known as an Annus Mirabilis. Fort Niagara and Fort Carillon on 8 July 1758 fell to sizable British forces, cutting off French frontier forts further west. On 13 September 1759, following a three-month siege of Quebec, General James Wolfe defeated the French on the Plains of Abraham outside the city. The French staged a counteroffensive in the spring of 1760, with initial success at the Battle of Sainte-Foy, but they were unable to retake Quebec, due to British naval superiority following the battle of Neuville. The French forces retreated to Montreal, where on 8 September they surrendered to overwhelming British numerical superiority.
