The scattered French posts along the summit were easily dispersed, while the main army at Beauport, some miles away, on the far side of the city, were as yet unconscious of danger. Bougainville and his force back at Cap Rouge were as far off and as yet no wiser. Quebec had just caught the alarm, but its weak and heterogeneous garrison had no power for combined mobility. By six o'clock Wolfe had his whole force of forty-three hundred men drawn up on the plateau, with their backs to the river and their faces to the north. Leaving the Royal Americans, five hundred forty strong, to guard the landing-place, and with a force thus reduced to under four thousand he now marched toward the city, bringing his left round at the same time in such fashion as to face the western walls, scarcely a mile distant. As Wolfe drew up his line of battle on that historic ridge of table-land known as the Plains of Abraham, his right rested on the cliff above the river, while his left approached the then brushy slope which led down toward the St. Charles Valley. He had outmanoeuvred Montcalm; it now remained only to crush him. Of this Wolfe had not much doubt, though such confidence may seem sufficiently audacious for the leader of four thousand men, with twice that number in front of him and half as many in his rear, both forces commanded by brave and skilful generals. But Wolfe counted on quality, not on numbers, which Montcalm himself realized were of doubtful efficacy at this crucial moment. The French general, in the mean time, had been expecting an attack all night at Beauport, and his troops had been lying on their arms. It was about six o'clock when the astounding news was brought him that the British were on the plateau behind the city. The Scotch Jacobite, the Chevalier Johnstone, who has left us an account of the affair, was with him at the time, and they leaped on their horses--he to give the alarm toward Montmorency, the general to hasten westward by Vaudreuil's quarters to the city. "This is a serious business," said Montcalm to Johnstone as he dug his spurs into his horse's flanks. Vaudreuil, who in his braggart, amateur fashion had been "crushing the English" with pen and ink and verbal eloquence this last six weeks, now collapsed, and Montcalm, who knew what a fight in the open with Wolfe meant, hastened himself to hurry forward every man that could be spared.
