Two days after Burgoyne had published his formidable proclamation, he appeared before Ticonderoga, then garrisoned by General St. Clair with about 3,000 men. Spite of all the labour and expense which had been bestowed on this fort, one important circumstance had been most singularly overlooked. The fort was commanded by a neighbouring height, called Mount Defiance, which being considered inaccessible, had been left undefended. Burgoyne, however, at once perceiving the advantage to be obtained by the possession of this height, lost no time in preparing to gain it, and three days after he had made his appearance, his artillery was placed on the summit. St. Clair seeing that no chance remained for himself and his troops, resolved upon immediate evacuation. The baggage and stores, under the convoy of the last remains of the American flotilla, were secretly despatched down to Skeensborough, and the troops also in two divisions, the one under St. Clair, the other, which left two hours later, under Colonel Francis, commenced their retreat at the dead of night, but were discovered by the enemy owing to the accidental burning of a building on an adjoining height. The next morning, therefore, the rear division was overtaken by General Fraser at the head of a British troop, near Hubbardton, where an engagement took place, in which the Americans were routed, and flying before the enemy, spread throughout the adjoining country the terror of the British arms. One thousand Americans were killed, wounded and taken prisoners on this disastrous day, among the former of whom was Colonel Francis. Nor was this all; General Reidesel with a corps of Germans pursued and overtook the American stores and baggage, which fell into his hands; and the garrison of Skeensborough, on learning this melancholy intelligence and of the approach of Burgoyne, set fire to the works, and fled to Fort Anne, half-way between them and the Hudson. Pursuit followed; a skirmish took place, and in the infectious terror of the time, having set fire to the works of Fort Anne, they fled to Fort Edward, the head-quarters of General Schuyler. At this same point, also, arrived St. Clair, who with his division had been wandering about for seven days. Thus, after defeat and flight, were assembled the whole force of the American northern army, amounting only to 5,000 men, many of whom were only hastily-summoned militia, wholly unorganised, while of ammunition there was great scarcity.
