The Americans, however, still retained their hold on Lake Champlain. It was impossible to dislodge them without organizing transport by water as well as by land, and building armed vessels to overpower the ships with which they commanded the lake. For when they overran Canada as far as Quebec, they secured all the sailing craft and bateaux on the Upper St. Lawrence. ‘The task was indeed arduous,’ says a contemporary writer, ‘a fleet of above thirty fighting vessels, of different kinds and sizes, all furnished with cannon, was to be little less than recreated.’[100] Three months, therefore, were taken up in boat-building, the material being in large measure sent out from England, in making roads, constructing entrenchments, drilling the troops, and collecting supplies. The troops, over 10,000 in number, were stationed at La Prairie on the St. Lawrence, immediately opposite Montreal, at Chambly, St. John’s, and the Isle aux Noix, with detachments lower down the Richelieu river than Chambly in order to keep all the communications open; and in September, when the preparations were nearly completed, advanced parties were moved forward to the opening of Lake Champlain.

On the 11th they came into touch with the American vessels, which were then stationed, under Arnold’s command, between Valcour Island and the western shore of the lake. The place was about five miles south of Plattsburg, about twenty-five miles south of what is now the boundary line of Canada, and a little less than fifty miles to the north of Crown Point. The strait between the island and the mainland is about a mile wide, and across it was the American line of battle. The English had the superiority in numbers and, as the result of the first day’s fighting, being carried to the south of the enemy’s ships, were at the close of the day drawn up in line to intercept their retreat. At night, however, Arnold, bold and skilful as ever, found a passage through and sailed off to the south, hotly pursued by Carleton’s squadron. On the 13th fighting began again, and ended with the capture or destruction of twelve American vessels, out of a total of fifteen, over 100 prisoners being taken including the second in command to Arnold. Crown Point was set on fire and abandoned by the Americans, and on the 14th Carleton wrote from his ship off that place reporting his success. In his dispatch he expressed doubts whether anything further could be done at that late season of the year, and he subsequently came to the conclusion that an attack on Ticonderoga, which was held by a strong force under Gates, must be postponed till the following spring. Nor did he think it prudent to occupy Crown Point, which
