Small successes about this time, important in the aggregate result, tended materially to keep up the spirits of the American troops, and made them eager to encounter the main body of the enemy. General Lincoln, with about two thousand militia, got in the rear of Burgoyne, and, by dividing his force into detachments, operated with much effect. One detachment, under Colonel Brown, surprised the British posts on Lake George, captured a vessel containing provisions for the enemy, took possession of Mount Hope and Mount Defiance, and, appearing before Ticonderoga, demanded its surrender. But the walls and garrison were too strong, and, after a cannonade of four days, the siege was abandoned, and all the troops prepared to unite and attack the enemy in the rear. The threatening aspect of this movement of Lincoln at the beginning, and the probability of having his supplies from the lakes cut off, induced Burgoyne, in self-defense, to move forward and execute promptly what he intended to do. Having, by great diligence, brought forward provisions for about thirty days, he advanced along the left bank of the Hudson to the mouth of the Batten Kill, where he encamped preparatory to crossing the river. * His officers were somewhat divided in opinion in regard to the expediency of further attempts to reach Albany; and it had been plainly intimated to Burgoyne that it might be greater wisdom to fall back from Fort Edward, rather than advance, for it was evident that perils of no ordinary kind were gathering around the invading army.
