“Your character, sir,” writes he, “induces me to hope I am ill informed. Nevertheless, the duty I owe the troops committed to my charge, lays me under the necessity of acquainting your Excellency, that, if you allow this conduct and persist in it, I shall, though with the most painful regret, execute with rigor the just and necessary law of retaliation upon the garrison of Chamblee, now in my possession, and upon all others who may hereafter fall into my hands. * * * * I shall expect your Excellency’s answer in six days. Should the bearer not return in that time, I must interpret your silence into a declaration of a barbarous war. I cannot pass this opportunity without lamenting the melancholy and fatal necessity, which obliges the firmest friends of the constitution to oppose one of the most respectable officers of the crown.” While waiting for a reply, Montgomery pressed the siege of St. Johns, though thwarted continually by the want of subordination and discipline among his troops; hasty levies from various colonies, who, said he, “carry the spirit of freedom into the field, and think for themselves.” Accustomed as he had been, in his former military experience, to the implicit obedience of European troops, the insubordination of these yeoman soldiery was intolerable to him. “Were I not afraid,” writes he, “the example would be too generally followed, and that the public service might suffer, I would not stay an hour at the head of troops whose operations I cannot direct. I must say I have no hopes of success, unless from the garrison’s wanting provisions.” He had advanced his lines and played from his batteries on two sides of the fort for some hours, when tidings brought by four prisoners, caused him to cease his fire. General Carleton, on the 31st of September, had embarked his motley force at Montreal in thirty-four boats, to cross the St. Lawrence, land at Longueil, and push on for St. Johns, where, as concerted, he was to be joined by Maclean and his Highlanders. As the boats approached the right bank of the river at Longueil, a terrible fire of artillery and musketry was unexpectedly opened upon them, and threw them into confusion. It was from Colonel Seth Warner’s detachment of Green Mountain Boys and New Yorkers. Some of the boats were disabled, some were driven on shore on an island; Carleton retreated with the rest to Montreal, with some loss in killed and wounded. The Americans captured two Canadians and two Indians; and it was these prisoners who brought tidings to the camp of Carleton’s signal repulse. Aware that the garrison held out merely in expectation of the relief thus intercepted, Montgomery ceased his fire, and sent a flag by one of the Canadian prisoners with a letter informing Major Preston of the event, and inviting a surrender to spare the effusion of blood.
