While Gates was intriguing, Schuyler was doing all in his power to impede the enemy's progress. It was on the night of July 5 that the garrison of Ticonderoga, under General St. Clair, had abandoned the fortress and retreated southward. On the 7th a battle was fought at Hubbardton between St. Clair's rear, under Seth Warner, and a portion of the British army under Fraser and Riedesel. Warner was defeated, but only after such an obstinate resistance as to check the pursuit, so that by the 12th St. Clair was able to bring his retreating troops in safety to Fort Edward, where they were united with Schuyler's army. Schuyler managed his obstructions so well that Burgoyne's utmost efforts were required to push into the wilderness at the rate of one mile per day; and meanwhile Schuyler was collecting a force of militia in the Green Mountains, under General Lincoln, to threaten Burgoyne in the rear and cut off his communications with Lake Champlain. Burgoyne was accordingly marching into a trap, and Schuyler was doing the best that could be done. But on the first of August the intrigue against him triumphed in Congress, and Gates was appointed to supersede him in the command of the northern army. Gates, however, did not arrive upon the scene until the 19th of August, and by that time Burgoyne's situation was evidently becoming desperate. On the last day of July Burgoyne reached Fort Edward, which Schuyler had evacuated just before. Schuyler crossed the Hudson river, and continued his retreat to Stillwater, about thirty miles above Albany. It was as far as the American retreat was to go. Burgoyne was already getting short of provisions, and before he could advance much further he needed a fresh supply of horses to drag the cannon and stores. He began to realize, when too late, that he had come far into an enemy's country. The hostile feelings of the people were roused to fury by the atrocities committed by the Indians employed in Burgoyne's army. The British supposed that the savages would prove very useful as scouts and guides, and that by offers of reward and threats of punishment they might be restrained from deeds of violence. They were very unruly, however, and apt to use the tomahawk when they found a chance. [Sidenote: Jane McCrea.]
