At once upon the outbreak of hostilities at Lexington, the conquest of Canada had been contemplated by the Northern leaders, who well remembered how, in days gone by, the valley of the St. Lawrence had furnished a base for attacks upon the province of New York, which was then the strategic centre of the American world. It was deemed an act of military prudence to secure this region at the outset. But so long as the least hope of conciliation remained, Congress was unwilling to adopt any measures save such as were purely defensive in character. [The Americans invade Canada, Sept., 1775]As we have seen, it was only with reluctance that it had sanctioned the garrisoning of Ticonderoga by the Connecticut troops. But in the course of the summer it was learned that the governor of Canada, Sir Guy Carleton, was about to take steps to recover Ticonderoga; and it was credibly reported that intrigues were going on with the Iroquois tribes, to induce them to harry the New England frontier and the pleasant farms on the Hudson: so that, under these circumstances, the invasion of Canada was now authorized by Congress as a measure of self-defence. An expedition down Lake Champlain, against Montreal, was at once set on foot. As Schuyler, the commander of the northern department, was disabled by ill health, the enterprise was confided to Richard Montgomery, an officer who had served with distinction under Wolfe. Late in August, Montgomery started from Ticonderoga, and on the 12th of September, with a force of two thousand men, he laid siege to the fortress of St. John’s, which commanded the approach to Montreal. Carleton, whose utmost exertions could bring together only some nine hundred men, made heroic but fruitless efforts to stop his progress. After a siege of fifty days, St. John’s surrendered on the 3d of November, and on the 12th Montgomery entered Montreal in triumph. The people of Canada had thus far seemed favourably disposed toward the American invaders, and Montgomery issued a proclamation urging them to lose no time in choosing delegates to attend the Continental Congress.

Meanwhile, in September, Washington had detached from the army at Cambridge one thousand New England infantry, with two companies of Pennsylvania riflemen and Morgan’s famous Virginia sharpshooters, and ordered them to advance upon Quebec through the forests of Maine and by way of the rivers Kennebec and Chaudière. [Arnold’s march through the wilderness of Maine]The expedition was commanded by Colonel Benedict Arnold, who seems to have been one of the first, if not the first, to suggest it. Such plans of invading an enemy’s territory, involving the march of independent forces upon convergent lines from remote points, were much more in favour with military men a century ago than to-day. The vice of such methods was often illustrated during our Revolutionary War. The vast distances and total lack of communication made effective coöperation between Montgomery and Arnold impossible; while a surprise of Quebec by the latter, with force sufficient to capture it unaided, was almost equally out of the question. But the very difficulty of the scheme commended it to the romantic and buoyant temper of Benedict Arnold. The enterprise was one to call for all his persistent daring and fertile resource. It was an amphibious journey, as his men now rowed their boats with difficulty against the strong, swift current of the Kennebec, and now, carrying boats and oars on their shoulders, forced their way through the tangled undergrowth of the primeval forests. Often they had to wade across perilous bogs, and presently their shoes were cut to pieces by sharp stones, and their clothes torn to shreds by thorns and briers. Their food gave out, and though some small game was shot, their hunger became such that they devoured their dogs. When they reached the head of the Chaudière, after this terrible march of thirty-three days, two hundred of their number had succumbed to starvation, cold, and fatigue, while two hundred more had given out and returned to Massachusetts, carrying with them such of the sick and disabled as they could save. The descent of the Chaudière in their boats afforded some chance for rest, and presently they began to find cattle for food. At last, on the 13th of November, the next day after Montgomery’s capture of Montreal, they crossed the broad St. Lawrence, and climbed the Heights of Abraham at the very place where Wolfe had climbed to victory sixteen years ago. There was splendid bravado in Arnold’s advancing to the very gates with his little, worn-out army, now reduced to seven hundred men, and summoning the garrison either to come out and fight, or to surrender the town. But the garrison very properly would neither surrender nor fight. The town had been warned in time, and Arnold had no alternative but to wait for Montgomery to join him.

Six days afterward, Carleton, disguised as a farmer, and ferried down stream in a little boat, found his way into Quebec; and on the 3d of December, Montgomery made his appearance with a small force, which raised the number of the Americans to twelve hundred men. As Carleton persistently refused to come out of his defences, it was resolved to carry the works by storm,—a chivalrous, nay, one might almost say, a foolhardy decision, had it not been so nearly justified by the event. [Assault upon Quebec, Dec. 31, 1775]On the last day of 1775, England came within an ace of losing Quebec. At two o’clock in the morning, in a blinding snowstorm, Montgomery and Arnold began each a furious attack, at opposite sides of the town; and aided by the surprise, each came near carrying his point. Montgomery had almost forced his way in when he fell dead, pierced by three bullets; and this so chilled the enthusiasm of his men that they flagged, until reinforcements drove them back. Arnold, on his side, was severely wounded and carried from the field; but the indomitable Morgan took his place, and his Virginia company stormed the battery opposed to them, and fought their way far into the town. Had the attack on the other side been kept up with equal vigour, as it might have been but for Montgomery’s death, Quebec must have fallen. As it was, Morgan’s triumphant advance only served to isolate him, and presently he and his gallant company were surrounded and captured.

[Total failure of the attempt upon Canada] With the failure of this desperate attack passed away the golden opportunity for taking the citadel of Canada. Arnold remained throughout the winter in the neighbourhood of Quebec, and in the spring the enterprise was taken up by Wooster and Sullivan with fresh forces. But by this time many Hessians had come over, and Carleton, reinforced until his army numbered 13,000, was enabled to recapture Montreal and push back the Americans, until in June, after a hazardous retreat, well conducted by Sullivan, the remnant of their invading army found shelter at Crown Point. Such was the disastrous ending of a campaign which at the outset had promised a brilliant success, and which is deservedly famous for the heroism and skill with which it was conducted. The generalship of Montgomery received the warm approval of no less a critic than Frederick the Great; and the chivalrous bravery of Arnold, both in his march through the wilderness and in the military operations which followed, was such that if a kind fate could then and there have cut the thread of his life, he would have left behind him a sweet and shining memory. As for the attempt to bring Canada into the American union, it was one which had no hope of success save through a strong display of military force. The sixteen years which had elapsed since the victory of Wolfe had not transformed the Canadian of the old régime into a free-born Englishman. The question at present for him was only that of a choice of allegiance, and while at first the invaders were favourably received, it soon became apparent that between the Catholic and the Puritan there could be but little real sympathy. The Quebec Act, which legalized Catholic worship in Canada, had done much toward securing England’s hold upon this part of her American possessions. And although, in the colourless political condition of this northern province, the capture of Quebec might well have brought it into the American union, where it would gradually have taken on a fresh life, as surely as it has done under British guidance, yet nothing short of such a military occupation could have had any effect in determining its languid preferences.

[The siege of Boston] While Canada was thus freed from the presence of the Continental troops, the British army, on the other hand, was driven from Boston, and New England was cleared of the enemy. During the autumn and winter, Washington had drawn his lines as closely as possible about the town, while engaged in the work of organizing and equipping his army. The hardest task was to collect a sufficient quantity of powder and ball, and to bring together siege-guns. As the season wore on, the country grew impatient, and Washington sometimes had to listen to criticisms like those that were directed against McClellan in Virginia, at the beginning of 1862, or against Grant before Vicksburg, in the spring of 1863. President Hancock, who owned a great deal of property in Boston, urged him to set fire to the town and destroy it, if by so doing he could drive the British to their ships. But Washington had planned much more wisely. By the 1st of March a great quantity of cannon had been brought in by Henry Knox, some of them dragged on sledges all the way from Ticonderoga, and so at last Washington felt himself prepared to seize upon Dorchester Heights. This position commanded the town and harbour even more effectually than Bunker Hill, and why in all these months General Howe had not occupied it one would find it hard to say. He was bitterly attacked for his remissness by the British newspapers, as was quite natural.
