From The Plains of Abraham by Brian Connell:
According to the field state on the morning of September 13th, Wolfe had with him, when all the men had reached the top of the cliff, 4,828 combatants of all ranks.
Wolfe relied on one factor to tip the balance of the day--his men were all regulars, including the two battalions of the Royal Americans, who had been drilled up to his exacting standards. For the first time in the course of the war in North America they were in a position to fight on their own terms--in the open field, where their superb, mechanical discipline and massed fire power would tell to the utmost.
The area in between (Buttes a Neveu ridge and Quebec), mostly green pasture with a few cornfields, studded here and there with clumps of bushes derived its name from Abraham Martin, a pilot who had owned part of the land in the early years of the colony, and was called the Plains of Abraham.
