Alarm guns were fired, and in less than an hour the British flag was hoisted over the empty fortress, while General Fraser, with 900 men, had started in hot pursuit of the retreating Americans. Riedesel was soon sent to support him, while Burgoyne, leaving nearly 1,000 men to garrison the fort, started up the lake with the main body of the army. On the morning of the 7th, General Fraser overtook the American rear-guard of 1,000 men, under Colonels Warner and Francis, at the village of Hubbardton, about six miles behind the main army. A fierce fight ensued, in which Fraser was worsted, and had begun to fall back, with the loss of one fifth of his men, when Riedesel came up with his Germans, and the Americans were put to flight, leaving one third of their number killed or wounded. This obstinate resistance at Hubbardton served to check the pursuit, and five days later St. Clair succeeded, without further loss, in reaching Fort Edward, where he joined the main army under Schuyler. [Illustration: TRUMBULL'S PLAN OF TICONDEROGA AND MOUNT DEFIANCE] [Sidenote: One swallow does not make a summer] Up to this moment, considering the amount of work done and the extent of country traversed, the loss of the British had been very small. They began to speak contemptuously of their antagonists, and the officers amused themselves by laying wagers as to the precise number of days it would take them to reach Albany. In commenting on the failure to occupy Mount Defiance, Burgoyne made a general statement on the strength of a single instance,--which is the besetting sin of human reasoning. "It convinces me," said he, "that the Americans have no men of military science." Yet General Howe at Boston, in neglecting to occupy Dorchester Heights, had made just the same blunder, and with less excuse; for no one had ever doubted that batteries might be placed there by somebody.
