While these preparations were in progress, Carleton, informed of the capture cf Fort Chambly, left Montreal with a re-enforcement for the garrison at St. John's. He embarked upon the St. Lawrence in bateaux and flat-boats, and attempted to land at Longueuil, a mile and a half below the city. Colonel Seth Warner, with three hundred Green Mountain Boys, was on the alert in the neighborhood, and lay in covert near the spot where Carleton was about to land. He allowed the boats to get very near the shore, when he opened a terrible storm of grape-shot upon them from a four pound cannon, which drove them across the river precipitately and in great confusion. The tidings of this event reached Montgomery November 1, 1775 toward evening, and Colonel Warner soon afterward came in with several prisoners captured from one of Carleton's boats that reached the shore. The eommander-in-chief immediately sent a flag and letter to Major Preston, the commandant of the garrison, by one of Warner's prisoners, informing him of the defeat of Carleton, and demanding a surrender of the fortress to prevent further effusion of blood. Hostilities ceased for the night, and in the morning Preston asked for a delay of four days before he should make proposals to surrender. The request "was denied and the demand renewed." There was no alternative, and the garrison surrendered prisoners of war. The siege had continued six weeks, and the bravery and perseverance of the British troops were such, that Montgomery granted them honorable terms. They marched out of the fort with the honors of war, and the troops * This is a view of the south and west sides of the fort, looking toward the river. It stands directly upon the Richelieu, at the foot of the Chambly Rapids, and at the head of the navigation of the river up from the St. Lawrence. It is strongly built of stone, and, as seen in the picture, is in a state of excellent preservation. ** The spoils taken at Chambly were 6 tons of powder; 80 barrels of flour; a large quantity of rice, butter, and peas; 134 barrels of pork; 300 swivel shot; 1 box of musket shot; 6364 musket cartridges; 150 stand of French arms; 3 royal mortars; 61 shells; 500 hand grenades; 83 royal fusilleer's muskets with accouterments; and rigging for 3 vessels. The prisoners consisted of 1 major, 2 captains, 3 lieutenants, captain of a schooner, a commissary and surgeon, and 83 privates. The colors of the seventh regiment of British regulars were there, and were captured. These were sent to the Continental Congress, and were the first trophies of the kind which that body received. There were a great number of women and children in the fort, and these were allowed to accompany the prisoners, who were sent with their baggage to Connecticut. Surrender of St. John's.--Insubordination.--Retreat of the Americans out of Canada.
