Despite his courage and the new resolution that he had acquired during his long months on the island, Robert's heart often sank. They seemed to make no progress with the siege of Quebec. Just so far had they gone and they could go no farther. The fortress of France in the New World appeared impregnable. There it was, cut clear against the sky, the light shining on its stone buildings, proud and defiant, saying with every new day to those who attacked it that it could not be taken, while Montcalm, De Levis, Bougainville, St. Luc and the others showed all their old skill in defense. They heard too that Bourlamaque after his retreat from Ticonderoga and Crown Point was sitting securely within his lines and intrenchments at Isle-aux-Noix and that the cautious Amherst would delay longer and yet longer. It was now certain that no help could be expected from Amherst and his strong army that year. The most that he would do would be to keep Bourlamaque and his men from coming to the relief of Quebec. So far as the capital of New France was concerned the issue must be fought out by the forces now gathered there for the defense and the offense, the French and the Indians against the English and the Americans. Robert realized more keenly every day that the time was short and becoming shorter. Hot summer days were passing, nights came on crisp and cool, the foliage along the king of rivers and its tributaries began to glow with the intense colors of decay, there was more than a touch of autumn in the air. They must be up and doing before the fierce winter came down on Quebec. Military operations would be impossible then. In this depressing time Robert drew much courage from Charteris, who had been a prisoner a long time in Quebec, and who understood even more thoroughly than young Lennox the hollowness of the French power in North America. "It is upheld by a few brave and skillful men and a small but heroic army," he said. "In effect, New France has been deserted by the Bourbon monarchy. If it were not for the extraordinary situation of Quebec, adapted so splendidly to purposes of defense, we could crush the Marquis de Montcalm in a short time. The French regulars are as good as any troops in the world and they will fight to the last, but the Canadian militia is not disciplined well, and is likely to break under a fierce attack. You know, Lennox, what militiamen always are, no matter to what nation they belong. They may fight and die like heroes at one time, and, at another time, they may run away at the first fire, struck with panic. What we want is a fair chance at the French army in the open. General Wolfe himself, though cursed by much illness, never loses hope. I've had occasion to talk with him more than once owing to my knowledge of Quebec and the surrounding country, and there's a spirit for you, Lennox. It's in an ugly body but no man was ever animated by a finer temper and courage."
