Stirling, who, by Washington's orders, had visited and inspected the defences in the Highlands, rendered a report of their condition, of which we give the purport. Fort Montgomery, at the lower part of the Highlands, was on the west bank of the river, north of Dunderberg (or Thunder Hill). It was situated on a bank one hundred feet high. The river at that place was about half a mile wide. Opposite the fort was the promontory of Anthony's Nose, many hundred feet high, accessible only to goats, or men expert in climbing. A body of riflemen stationed here might command the decks of vessels. Fort Montgomery appeared to Lord Stirling the proper place for a guard post. Fort Constitution was about six miles higher up the river, on a rocky island of the same name, at a narrow strait where the Hudson, shouldered by precipices, makes a sudden bend round West Point. A redoubt, in the opinion of Lord Stirling, would be needed on the point, not only for the preservation of Fort Constitution, but for its own importance.
The garrison of that fort consisted of two companies of Colonel James Clinton's regiment, and Captain Wisner's company of minute men, in all one hundred and sixty rank and file. Fort Montgomery was garrisoned by three companies of the same regiment, about two hundred rank and file. Both garrisons were miserably armed. The direction of the works of both forts was in the hands of commissioners appointed by the Provincial Congress of New York. The general command of the posts required to be adjusted.
In view of all these circumstances, Washington, on the 14th of June, ordered Colonel James Clinton to take command of both posts, and of all the troops stationed at them. He seemed a fit custodian for them, having been a soldier from his youth; brought up on a frontier subject to Indian alarms and incursions, and acquainted with the strong points and fastnesses of the Highlands.
King's Bridge, and the heights adjacent, considered by General Lee of the utmost importance to the communication between New York and the mainland, and to the security of the Hudson, were reconnoitred by Washington on horseback, about the middle of the month; ordering where works should be laid out. Breastworks were to be thrown up for the defence of the bridge, and an advanced work (subsequently called Fort Independence) was to be built beyond it, on a hill commanding Spyt den Duivel Creek, as that inlet of the Hudson is called, which links it with the Harlem River. A strong work, intended as a kind of citadel, was to crown a rocky height between two and three miles south of the bridge, commanding the channel of the Hudson, and below it were to be redoubts on the banks of the river at Jeffrey's Point. In honor of the general, the citadel received the name of Fort Washington. While these preparations were made for the protection of the Hudson, the works about Brooklyn on Long Island were carried on with great activity, under the superintendence of General Greene. In a word, the utmost exertions were made at every point, to put the city, its environs, and the Hudson River, in a state of defence, before the arrival of another hostile armament.
Operations in Canada were now drawing to a disastrous close. General Thomas, finding it impossible to make a stand at Point Deschambault, had continued his retreat to the mouth of the Sorel, where he found General Thompson with part of the troops detached by Washington, from New York, who were making some preparations for defence. Shortly after his arrival, he was taken ill with the small-pox, and removed to Chamblee. He had prohibited inoculation among his troops, because it put too many of their scanty number on the sick list; he probably fell a victim to his own prohibition, as he died of that malady on the 2d of June.
On his death, General Sullivan, who had recently arrived with the main detachment of troops from New York, succeeded to the command; General Wooster having been recalled. He advanced immediately with his brigade to the mouth of the Sorel, where he found General Thompson with but very few troops to defend that post, having detached Colonel St. Clair, with six or seven hundred men, to Three Rivers, about fifty miles down the St. Lawrence, to give check to an advanced corps of the enemy of about eight hundred regulars and Canadians, under the veteran Scot, Colonel Maclean. Sullivan proceeded forthwith to complete the works on the Sorel; in the meantime he detached General Thompson with additional troops to overtake St. Clair and assume command of the whole party, which would then amount to two thousand men. He was by no means to attack the encampment at Three Rivers, unless there was great prospect of success, as his defeat might prove the total loss of Canada.
Sullivan was aiming at the command in Canada; and Washington soberly weighed his merits for the appointment, in a letter to the President of Congress. "He is active, spirited, and zealously attached to the cause. He has his wants and he has his foibles.... He wants experience to move upon a grand scale; for the limited and contracted knowledge, which any of us have in military matters, stands in very little stead." Scarce had Washington despatched this letter, when he received one from the President of Congress, dated the 18th of June, informing him that Major-general Gates had been appointed to command the forces in Canada, and requesting him to expedite his departure as soon as possible. The appointment of Gates has been attributed to the influence of the Eastern delegates, with whom he was a favorite; indeed, during his station at Boston, he had been highly successful in cultivating the good graces of the New England people. He departed for his command on the 26th of June, vested with extraordinary powers for the regulation of affairs in that "distant, dangerous, and shifting scene."
The actual force of the enemy in Canada had recently been augmented to about 13,000 men; several regiments having arrived from Ireland, one from England, another from General Howe, and a body of Brunswick troops under the Baron Reidesel. Of these, the greater part were on the way up from Quebec in divisions, by land and water, with Generals Carleton, Burgoyne, Philips and Reidesel; while a considerable number under General Frazer had arrived at Three Rivers, and others, under General Nesbit, lay near them on board of transports.
General Thompson coasted in bateaux along the right bank of the river at that expanse called Lake St. Pierre, and arrived at Nicolete, where he found St. Clair and his detachment. He crossed the river in the night, and landed a few miles above Three Rivers, intending to surprise the enemy before daylight; he was not aware at the time that additional troops had arrived under General Burgoyne. After landing, he marched with rapidity toward Three Rivers, but was led by treacherous guides into a morass, and obliged to return back nearly two miles. Day broke, and he was discovered from the ships. A cannonade was opened upon his men as they made their way slowly for an hour and a half through a swamp. At length they arrived in sight of Three Rivers, but it was to find a large force drawn up in battle array, under General Frazer, by whom they were warmly attacked, and after a brief stand thrown in confusion. Thompson attempted to rally his troops, and partly succeeded, until a fire was opened upon them in rear by Nesbit, who had landed from his ships. Their rout now was complete. General Thompson, Colonel Irvine, and about two hundred men were captured, twenty-five were slain, and the rest pursued for several miles through a deep swamp. After great fatigues and sufferings, they were able to get on board of their boats, which had been kept from falling into the hands of the enemy. In these they made their way back to the Sorel, bringing General Sullivan the alarming intelligence of the overpowering force that was coming up the river.
Sullivan made the desperate resolve to defend the mouth of the Sorel, but was induced to abandon it by the unanimous opinion of his officers, and the evident unwillingness of his troops. Dismantling his batteries, therefore, he retreated with his artillery and stores just before the arrival of the enemy, and was followed, step by step along the Sorel, by a strong column under General Burgoyne. On the 18th of June he was joined by General Arnold with three hundred men, the garrison of Montreal, who had crossed at Longueil just in time to escape a large detachment of the enemy. Thus reinforced, and the evacuation of Canada being determined on in a council of war, Sullivan succeeded in destroying everything at Chamblee and St. Johns that he could not carry away, breaking down bridges, and leaving forts and vessels in flames, and continued his retreat to the Isle aux Noix, where he made a halt for some days, until he should receive positive orders from Washington or General Schuyler. The low, unhealthy situation of the Isle aux Noix obliged him soon to remove his camp to the Isle la Motte, whence, on receiving orders to that effect from General Schuyler, he ultimately embarked with his forces, sick and well, for Crown Point.
Thus ended this famous invasion; an enterprise bold in
