In 1756, with the outbreak of open hostilities with France, Wolfe was promoted to colonel and participated in the failed British
amphibious assault on
Rochefort, a seaport on the French Atlantic coast, a year later. Nonetheless, Wolfe was one of the few military leaders who had distinguished himself in the raid. As a result, Wolfe was brought to the notice of the prime minister,
William Pitt, the Elder. Pitt had determined that the best gains in the war were to be made in North America. On 23 January, 1758, James Wolfe was appointed as a
brigadier general, and sent with Major General
Jeffrey Amherst to lay siege to
Fortress of Louisbourg in
New France (located in present-day Cape Breton Island, Nova Scotia). The French capitulated in June of that year.
Wolfe comported himself admirably at Louisbourg, and as a result, Pitt chose him to lead the British assault on
Quebec City the following year, with the rank of
major general. The British army laid
siege to the city for three months. During that time, Wolfe issued a written document, known as
Wolfe's Manifesto, to the French-Canadian (
Québécois) civilians, as a part of his strategy of psychological intimidation. In March 1759, prior to arriving at Quebec, Wolfe had written to Amherst: "If, by accident in the river, by the enemy’s resistance, by sickness or slaughter in the army, or, from any other cause, we find that Quebec is not likely to fall into our hands (persevering however to the last moment), I propose to set the town on fire with shells, to destroy the harvest, houses and cattle, both above and below, to send off as many Canadians as possible to Europe and to leave famine and desolation behind me; but we must teach these scoundrels to make war in a more gentleman like manner."
After an extensive yet unsuccessful shelling of the city, Wolfe then led 200 ships with 9000 soldiers and 18 000 sailors on a very bold and risky amphibious landing at the base of the cliffs west of Quebec along the
St. Lawrence River. His army, with two small cannons, scaled the cliffs early on the morning of
September 13, 1759, surprising the French under the command of the
Marquis de Montcalm, who thought the cliffs would be unclimbable. The French, faced with the possibility that the British would haul more cannons up the cliffs and knock down the city's remaining walls, fought the British on the
Battle of the Plains of Abraham. The French were defeated, but Wolfe was shot in the chest and died just as the battle was won. He reportedly heard cries of "They run," and thus died content that the victory had been achieved. The Battle of the Plains of Abraham is notable for causing the deaths of the top military commander on each side: Montcalm died the next day from his wounds. Wolfe's victory at Quebec enabled an assault on the French at
Montreal the following year. With the fall of that city, French rule in North America, outside of
Louisiana and the tiny islands of
Saint-Pierre and Miquelon, came to an end.
Wolfe's body was returned to
Britain and interred in the family vault in
St Alfege Church, Greenwich alongside his father (died in March 1759).
