Wolfe, however, was not there to see it. He had gone forward the day before. A dispatch-boat had come down from Durell to say that, in spite of his advanced squadron, Bougainville, Montcalm's ablest brigadier, had slipped through with twenty-three ships from France, bringing out a few men and a good deal of ammunition, stores, and food. This gave Quebec some sorely needed help. Besides, Montcalm had found out Pitt's plan; and nobody knew where the only free French fleet was now. It had wintered in the West Indies. But had it sailed for France or the St Lawrence? At the first streak of dawn on the 23rd Durell's look-out off Isle-aux-Coudres reported many ships coming up the river under a press of sail. Could the French West Indian fleet have slipped in ahead of Saunders, as Bougainville had slipped in ahead of Durell himself? There was a tense moment on board of Durell's squadron and in Carleton's camp, in the pale, grey light of early morning, as the bugles sounded, the boatswains blew their whistles and roared their orders, and all hands came tumbling up from below and ran to battle quarters with a rush of swift bare feet. But the incoming vanship made the private British signal, and both sides knew that all was well. For a whole week the great fleet of one hundred and forty-one ships worked their way through the narrow channel between Isle-aux-Coudres and the north shore, and then dared the dangers of the Traverse, below the island of Orleans, where the French had never passed more than one ship at a time, and that only with the greatest caution. The British went through quite easily, without a single accident. In two days the great Captain Cook had sounded and marked out the channel better than the French had in a hundred and fifty years; and so thoroughly was his work done that the British officers could handle their vessels in these French waters better without than with the French pilots. Old Captain Killick took the _Goodwill_ through himself, just next ahead of the _Richmond_, on board of which was Wolfe. The captured French pilot in the _Goodwill_ was sure she would be lost if she did not go slow and take more care. But Killick laughed at him and said: 'Damn me, but I'll convince you an Englishman can go where a Frenchman daren't show his nose!' And he did. On June 26 Wolfe arrived at the west end of the island of Orleans, in full view of Quebec. The twenty days' voyage from Louisbourg had ended and the twelve weeks' siege had begun. At this point we must take the map and never put it aside till the final battle is over. A whole book could not possibly make Wolfe's work plain to any one without the map. But with the map we can easily follow every move in this, the greatest crisis in both Wolfe's career and Canada's history.
