Instead of following him up, and hastening to co-operate with Wolfe, General Amherst proceeded to repair the works at Ticonderoga, and erect a new fort at Crown Point, though neither were in present danger of being attacked, nor would be of use if Canada were conquered. Amherst, however, was one of those cautious men, who, in seeking to be sure, are apt to be fatally slow. His delay enabled the enemy to rally their forces at Isle Aux Noix, and call in Canadian reinforcements, while it deprived Wolfe of that co-operation which, it will be shown, was most essential to the general success of the campaign. Wolfe, with his eight thousand men, ascended the St. Lawrence in the fleet, in the month of June. With him came Brigadiers, Monckton, Townshend and Murray, youthful and brave like himself, and like himself, already schooled in arms. Monckton, it will be recollected, had signalized himself, when a colonel, in the expedition in 1755, in which the French were driven from Nova Scotia. The grenadiers of the army were commanded by Colonel Guy Carleton, and part of the light infantry by Lieutenant-Colonel William Howe, both destined to celebrity in after years, in the annals of the American Revolution. Colonel Howe was brother of the gallant Lord Howe, whose fall in the preceding year was so generally lamented. Among the officers of the fleet, was Jervis, the future admiral, and ultimately Earl St. Vincent; and the master of one of the ships, was James Cook, afterwards renowned as a discoverer. About the end of June, the troops debarked on the large, populous, and well-cultivated Isle of Orleans, a little below Quebec, and encamped in its fertile fields. Quebec, the citadel of Canada, was strong by nature. It was built round the point of a rocky promontory, and flanked by precipices. The crystal current of the St. Lawrence swept by it on the right, and the river St. Charles flowed along on the left, before mingling with that mighty stream. The place was tolerably fortified, but art had not yet rendered it, as at the present day, impregnable. Montcalm commanded the post. His troops were more numerous than the assailants but the greater part were Canadians, many of them inhabitants of Quebec; and he had a host of savages. His forces were drawn out along the northern shore below the city, from the river St. Charles to the Falls of Montmorency, and their position was secured by deep intrenchments.
