The early part of the Seven Years' War was disastrous to England. The tide turned with the accession to power of the great war minister, William Pitt. In 1759, he sent General James Wolfe with a combined military and naval force to capture Quebec. The British troops numbered somewhat less than nine thousand, while Montcalm and Vaudreuil were posted to receive them, on positions almost impregnable, with an army of regulars, Canadians, and Indians, amounting in all to about sixteen thousand. The great height of the shores made the British ships of little or no use for purposes of attack.

Wolfe took possession of Point Levi, from which he bombarded Quebec. He also seized the high grounds just below the Montmorenci, and vainly tried to cross that stream above the cataract and gain the rear of Montcalm's army, which lay encamped along the shore from the Montmorenci to the city. Failing in this and every other attempt to force the enemy to a battle, he rashly resolved to attack them in front, up the steep declivities at the top of which they were intrenched. The grenadiers dashed forward prematurely and without orders, struggling desperately to scale the heights under a deadly fire. The result was a complete repulse, with heavy loss.
