It was conveniently called "The Battle of the Plains of Abraham."

According to http://en.wikipedia.org/wiki/Battle_of_the_Plains_of_Abraham
"The Battle of the Plains of Abraham was a pivotal battle in the North American theatre of the Seven Years' War. The confrontation, which began on September 13, 1759, was fought between the British Army and Navy, and the French Army, on a plateau just outside the walls of Quebec City. The battle involved fewer than 10,000 troops between both sides, but proved to be a deciding moment in the conflict between France and Britain over the fate of New France, influencing the later creation of Canada."
