Ever since the failure of the American invasion of Canada, it had been the intention of Sir Guy Carleton, in accordance with the wishes of the ministry, to invade New York by way of Lake Champlain, and to secure the Mohawk valley and the upper waters of the Hudson. The summer of 1776 had been employed by Carleton in getting together a fleet with which to obtain control of the lake. It was an arduous task. Three large vessels were sent over from England, and proceeded up the St. Lawrence as far as the rapids, where they were taken to pieces, carried overland to St. John's, and there put together again. Twenty gunboats and more than two hundred flat-bottomed transports were built at Montreal, and manned with 700 picked seamen and gunners; and upon this flotilla Carleton embarked his army of 12,000 men. [Sidenote: Arnold's preparations] To oppose the threatened invasion, Benedict Arnold had been working all the summer with desperate energy. In June the materials for his navy were growing in the forests of Vermont, while his carpenters with their tools, his sail-makers with their canvas, and his gunners with their guns had mostly to be brought from the coast towns of Connecticut and Massachusetts. By the end of September he had built a little fleet of three schooners, two sloops, three galleys, and eight gondolas, and fitted it out with seventy guns and such seamen and gunners as he could get together. With this flotilla he could not hope to prevent the advance of such an overwhelming force as that of the enemy. The most he could do would be to worry and delay it, besides raising the spirits of the people by the example of an obstinate and furious resistance. To allow Carleton to reach Ticonderoga without opposition would be disheartening, whereas by delay and vexation he might hope to dampen the enthusiasm of the invader. With this end in view, Arnold proceeded down the lake far to the north of Crown Point, and taking up a strong position between Valcour Island and the western shore, so that both his wings were covered and he could be attacked only in front, he lay in wait for the enemy. James Wilkinson, who twenty years afterward became commander-in-chief of the American army, and survived the second war with England, was then at Ticonderoga, on Gates's staff. Though personally hostile to Arnold, he calls attention in his Memoirs to the remarkable skill exhibited in the disposition of the little fleet at Valcour Island, which was the same in principle as that by which Macdonough won his brilliant victory, not far from the same spot, in 1814.
