On the 16th of September, the day after Schuyler’s departure for Ticonderoga, Montgomery proceeded to carry out the plans which had been concerted between them. Landing on the 17th at the place where they had formerly encamped, within a mile and a half of the fort, he detached a force of five hundred men, among whom were three hundred Green Mountain Boys under Colonel Seth Warner, to take a position at the junction of two roads leading to Montreal and Chamblee, so as to intercept relief from those points. He now proceeded to invest St. Johns. A battery was erected on a point of land commanding the fort, the ship yards and the armed schooner. Another was thrown up in the woods on the east side of the fort, at six hundred yards distance, and furnished with two small mortars. All this was done under an incessant fire from the enemy, which, as yet, was but feebly returned. St. Johns had a garrison of five or six hundred regulars and two hundred Canadian militia. Its commander, Major Preston, made a brave resistance. Montgomery had not proper battering cannon; his mortars were defective; his artillerists unpractised, and the engineer ignorant of the first principles of his art. The siege went on slowly, until the arrival of an artillery company under Captain Lamb, expedited from Saratoga by General Schuyler. Lamb, who was an able officer, immediately bedded a thirteen-inch mortar, and commenced a fire of shot and shells upon the fort. The distance, however, was too great, and the positions of the batteries were ill chosen. A flourishing letter was received by the general from Colonel Ethan Allen, giving hope of further reinforcement. “I am now,” writes he, “at the Parish of St. Ours, four leagues from Sorel to the south. I have two hundred and fifty Canadians under arms. As I march, they gather fast. You may rely on it, that I shall join you in about three days, with five hundred or more Canadian volunteers I could raise one or two thousand in a week’s time; but I will first visit the army with a less number, and, if necessary, go again recruiting. Those that used to be enemies to our cause, come cap in hand to me; and I swear by the Lord, I can raise three times the number of our army in Canada, provided you continue the siege. * * * The eyes of all America, nay, of Europe, are or will be on the economy of this army and the consequences attending it.”[13]
