Among the prizes secured by the capture of Ticonderoga and Crown Point was a quantity of materials for boat-building, which now became available. With ready Yankee aptitude, the soldiers turned their hands to the construction of batteaux for the transportation of the troops down the lake, and the surrounding forests rang for many a summer day with the busy stroke of axe and hammer.
Montgomery reached Crown Point in August, and upon receiving news that Carleton was preparing for offensive operations, and had several armed vessels at St. John's ready to transport his forces up the lake, at once set forth with what troops had arrived. With sweep and sail, the lazy flotilla of batteaux was urged down the lake to Isle la Motte, where Montgomery was joined by Schuyler, who though ill had hastened on from Albany. They then moved on to Isle aux Noix, and there so disposed their forces as to prevent the passage of the enemy's vessels. From this point they issued a proclamation to the Canadians, assuring them that their army was not in any way directed against them, but against the British, and inviting them to join in the struggle for liberty.
Ethan Allen, whose patriotic ardor had not been cooled by his recent rebuff, had, by invitation of the generals, accompanied them to Isle aux Noix. He held no commission, but was considered as an officer, and was upon occasion to be given the command of detachments. He was now employed, with Major Brown and accompanied by interpreters, to distribute this proclamation among the Canadians, and satisfactorily performed the duties assigned him. On the 6th of September, the American army, not more than a thousand strong, advanced toward St. John's, and landed a mile and a half from the fort. This they found too strong to warrant an assault, and after a reconnoissance, in which they were attacked by a party of Indians, and suffered a slight loss while inflicting a somewhat greater one, they withdrew next morning to the Isle aux Noix, to await the arrival of artillery and reinforcements. It was during these operations that the brave Captain Remember Baker was killed. He was held in great esteem by his friends, and his death, being the first that occurred in the military operations in this quarter, created more stir, says Ira Allen, than the death of a thousand later in the war. Montgomery's reinforcements having arrived, he again moved upon St. John's on the 17th, and laid siege to the place, but, with his undisciplined troops and slender supply of ammunition, his progress was slow. Parties were sent out through the country, and were favorably received by the Canadians, who contributed men and provisions, the latter the more valuable contribution.
At this time, much against his wishes, for he would rather have taken part in the siege, Ethan Allen was dispatched by Montgomery on a mission similar to that in which he was previously engaged. With a guard of about eighty men, mostly Canadians, he passed through the parishes on the Richelieu and up the St. Lawrence to Longueuil, "preaching politics," as he says, and meeting "with good success as an itinerant." On his way thence to La Prairie, he fell in with Major Brown, who was out on the same errand, and now proposed to Allen that they should attempt the capture of Montreal. His plan was, that Allen should return to Longueuil, and, there procuring canoes, cross his men to the island of Montreal, a little below the town; while Brown, with about 200 men, should cross above it. Allen readily fell in with it, and, making haste back to Longueuil, obtained a few boats and collected about thirty recruits. In the course of the night he got his party across the river, and, setting a guard between his position and the town, with orders to let no one pass, awaited the signal which Brown was to give when he had effected a crossing. Allen waited with growing impatience, while daylight grew and sunrise came. All the world began to be astir, and yet Brown made no sign. Unsupported as he now found himself, he was in sorry plight, and would have recrossed the river, but he had only boats enough to transport a third of his force at a time, and the attempt would certainly result in the capture of the other two thirds. He determined to maintain his ground if possible, and that, in any event, all should fare alike. He dispatched messengers to Brown at La Prairie, and to L'Assomption, to a Mr. Walker, who was in the interest of the Americans, urging them to hasten to his aid.
Montreal was already alarmed, and the governor and his party were preparing to retire on board the vessels of war, when a spy, who had escaped from Allen's guards, brought them information of Allen's condition. Upon this, Carleton marched out to attack the presumptuous invader, with forty regulars and "a mixed multitude" of Canadians, English, and Indians, numbering nearly 500, and Allen perceived that it would be a "day of trouble if not of rebuke."[66] About two o'clock in the afternoon, the British force began firing from the cover of woodpiles, ditches, and buildings, Allen's men returning the fusillade from positions quite as favorable, till near half the enemy began a flank movement on their right. Observing this, Allen dispatched half his force, under a volunteer named Dugan, to occupy a ditch on their flank; but Dugan took the opportunity to escape with his detachment, as did one Young, posted on the other flank with a small force, and Allen was left with only forty-five men, some of whom were wounded. He began a hopeless retreat, which was continued for a while. An officer pressing close upon the rear fired his gun at Allen, the ball whistling past his head. Allen's shot in turn missed his enemy, as both were out of breath with running. Allen now offered to surrender if assured of quarter for himself and his men, which was promised by this officer. Whereupon Allen gave up his sword and surrendered his party, dwindled to thirty-eight, seven of whom were wounded. A painted and half-naked Indian rushed toward them, and within a few yards aimed his gun at Allen, who, seizing the officer to whom he had delivered his sword, made a shield of him, and kept him spinning around, as the Indian swiftly circled about the two, in a vain attempt to fire a shot that should kill only the Green Mountain Boy. Another Indian then took part in the attack, and Allen's shrift would have been short, had not an Irishman and a Canadian come to his rescue. He was then well treated by his captors, walking to the town between a British officer and a French gentleman, who, though he had lost an eyebrow in the action, "was very merry and facetious." But when General Prescott, who throughout the war never missed an opportunity of exhibiting his brutality, met them at the barracks and learned that the prisoner was the captor of Ticonderoga, he showered a torrent of abuse upon him, while he shook his cane over his head. Allen shook his fist at the general, and told him "that was the beetle of mortality for him if he offered to strike." An officer whispered to Prescott that it was inconsistent with his honor to strike a prisoner. Prescott turned his wrath upon the Canadians, and ordered a sergeant's guard to kill thirteen of them; and when Allen had somewhat dramatically but successfully interposed to save their lives, Prescott roared at him, with an oath, "I will not execute you now, but you shall grace a halter at Tyburn!" By Prescott's orders he was taken on board a vessel of war and manacled like a common felon, and presently, with other prisoners, was sent to England. Landing at Falmouth, clad in the fawn-skin jacket and red woolen cap that he wore when taken, his strange appearance excited a curiosity that not a little gratified him. From his capture till he was exchanged in 1778, he suffered on shipboard and in prison, with brief intervals of kinder treatment, a hard and cruel captivity, from which he emerged, however, with a spirit unsubdued, and unswerving loyalty to his country's cause. The attempt upon Montreal has generally been characterized as rash; yet, if Brown had not, for some unexplained reason, failed to perform his part in it, it is more than probable the undertaking would have succeeded. It was one of those daring enterprises which if successful receive the highest praise, if unsuccessful are scouted as foolhardy.
Meanwhile the siege of St. John's progressed slowly, principally through lack of ammunition. But on the 18th of October the fort at Chambly, further down the river, and garrisoned by about 100 men of the British Seventh Regiment, surrendered to Majors Brown and Livingston, and among the most important of its captured stores were 120 barrels of gunpowder, which enabled Montgomery to push the siege with more vigor. As gratifying if not as useful was the capture of the colors of the regiment, the first trophy of the kind received by the Continental Congress.
General Carleton was making all possible efforts for the relief of St. John's, whose garrison of 500 regulars and about 200 other troops was bravely defending it. He had collected a force of 800 regulars, militia, and Indians, which he embarked at Montreal, with the design of landing at Longueuil and joining Colonel McLean at the mouth of the Richelieu, where that officer was posted with a few hundred Scotch emigrants and some Canadians. Colonel Seth Warner with 300 Green Mountain Boys was keeping close watch of Carleton's movements, and when the flotilla drew near the south shore of the St. Lawrence, the rangers poured upon it a destructive volley of small-arms and a shower of grapeshot from a four-pounder. Carleton's force retired in confusion, and when McLean's Canadians got news of the disaster they took French leave of him, and he with his Scotchmen retired in haste to Quebec. Left now without hope of relief, St. John's capitulated on the 3d of November, and a considerable number of cannon, a quantity of military stores, and 600 prisoners fell into the hands of the Americans. The prisoners were sent by way of Ticonderoga into the interior of New England.
Montgomery now marched to Montreal, which Carleton had secretly quitted the night before. The inhabitants proposed a capitulation, which Montgomery refused, as they were incapable of making any defense. Promising them perfect protection of person and property, he marched his army into the place, and took peaceable possession on the 13th.
Colonel Easton had been sent with a detachment to the mouth of the Richelieu, where he erected a battery of two guns, and, being reinforced by a gunboat from St. John's on the 17th, he captured, as they attempted to pass on their way to Quebec, eleven sail of armed vessels freighted with provisions and military stores, and having on board General Prescott and 120 officers and privates.
The term of enlistment of Warner's men having now expired, they presently returned to their homes, not long after to be recalled, with their leader, in the stress of the Northern winter, by the urgent appeal of the commander of the army in Canada.
