The Isle Aux Noix is a low unhealthy place, badly supplied with water; where the troops were so universally seized with fevers, as to compel General Sullivan to retire to the Isle Lamotte. At that place he received the orders of General Schuyler to embark on the lakes for Crown Point.
The armed vessels on the Sorel and St. Lawrence were destroyed, and the fortifications of Chamblée and St. John's set on fire. All the baggage of the army, and nearly all the military stores were saved.
The British army, during this whole retreat, followed close in the rear, and took possession of the different posts which the Americans had occupied, immediately after they were evacuated.
On the Sorel the pursuit stopped. The Americans had the command of the lake, and the British general deemed it prudent to wrest it from them before he advanced farther. To effect this, it was necessary to construct a number of vessels, which required time and labour. Meanwhile, General Gates was ordered to take command of the northern army, which was directed to be reinforced with six thousand militia.
Canada evacuated.
Thus terminated the enterprise against Canada. It was a bold, and, at one period, promised to be a successful effort to annex that extensive province to the United Colonies. The dispositions of the Canadians favoured the measure; and had Quebec fallen, there is reason to believe the colony would have entered cordially into the union. Had a few incidents turned out fortunately; had Arnold been able to reach Quebec a few days sooner, or to cross the St. Lawrence on his first arrival—or had the gallant Montgomery not fallen in the assault of the 31st December, it is probable the expedition would have been crowned with complete success. But the radical causes of failure, putting fortune out of the question, were to be found in the lateness of the season when the troops were assembled, in a defect of the preparations necessary for such a service, and still more in the shortness of the time for which the men were enlisted. Had the expedition been successful, the practicability of maintaining the country is much to be doubted. Whilst General Montgomery lay before Quebec, and expected to obtain possession of the place, he extended his views to its preservation. His plan required a permanent army of ten thousand men; strong fortifications at Jacques Cartier, and the rapids of Richelieu; and armed vessels in the river, above the last place. With this army and these precautions, he thought the country might be defended; but not with an inferior force.
It seems, therefore, to have been an enterprise requiring means beyond the ability of congress; and the strength exhausted on it would have been more judiciously employed in securing the command of the lakes George and Champlain, and the fortified towns upon them.
While General Carleton was making preparations to enter the lakes, General Schuyler was using his utmost exertions to retain the command of them. But, so great was the difficulty of procuring workmen and materials, that he found it impossible to equip a fleet which would be equal to the exigency. It consisted of only fifteen small vessels; the largest of which was a schooner mounting twelve guns, carrying six and four pound balls. The command of this squadron, at the instance of General Washington, was given to General Arnold.
General Carleton constructs a fleet.
With almost incredible exertions, the British general constructed a powerful fleet; and, afterwards, dragged up the rapids of St. Therese and St. John's, a vast number of long boats and other vessels, among which was a gondola weighing thirty tons. This immense work was completed in little more than three months; and, as if by magic, General Arnold saw on Lake Champlain, early in October, a fleet consisting of near thirty vessels; the largest of which, the Inflexible, carried eighteen twelve-pounders. Enters Lake Champlain.This formidable fleet, having on board General Carleton himself, and navigated by seven hundred prime seamen under the command of Captain Pringle, proceeded immediately in quest of Arnold, who was advantageously posted between the island of Valicour and the western main.
