But a danger more potent than the weakness of the garrison lurked in the silent heights of Sugar Loaf Hill, now better known as Mount Defiance, that, westward from Ticonderoga, and overlooking it and all its outworks, bars the horizon with rugged steeps of rock and sharp incline of woodland. Colonel John Trumbull, of Revolutionary and artistic fame, had suggested to General Gates the advisability of fortifying it, saying that it commanded both Ticonderoga and Mount Independence. The idea was ridiculed, and he obtained leave to test the truth of his assertion. A shot from a twelve-pounder on Mount Independence struck half way up the mountain, and a six-pound shot fired from the glacis of Ticonderoga struck near the summit. Yet the Americans did not occupy it then, nor now, though a consultation was held concerning it. It was decided that there were not men enough to spare for the purpose from the fortifications already established. St. Clair hoped, moreover, that Burgoyne would choose rather to assault than besiege his position, and an assault he thought he might successfully repel. The General Convention now sitting at Windsor sent Colonel Mead, James Mead, Ira Allen, and Captain Salisbury to consult with the commander of Ticonderoga on the defense of the frontier. While this committee was there, General Burgoyne advanced up the lake, and during his stay at Crown Point sent a force of 300, most of whom were Indians, to the mouth of Otter Creek to raid upon the settlers. The committee was refused any troops for the defense of the frontiers, but Colonel Warner was allowed to go with them, and presently raised men enough to repel this invasion. On the 1st of July Warner wrote from Rutland to the convention that the enemy had come up the lake with seventeen or eighteen gunboats, two large ships, and other craft, and an attack was expected every hour; that he was ordered to call out the militia of Vermont, Massachusetts, and New Hampshire, to join him as soon as possible, and desired them to call out the militia on the east side of the mountain, and to send forty or fifty head of beef cattle for Ticonderoga. "I shall be glad," he writes in conclusion, "if a few hills of corn unhoed should not be a motive sufficient to detain men at home, considering the loss of such an important post might be irretrievable." In view of the impending invasion of the British, the convention appointed a day of fasting and prayer, but this pious measure had no apparent effect on the movements of the enemy, and Burgoyne continued to advance. His army moved forward on either side of the lake, the war-craft to an anchorage just out of range of the guns of Ticonderoga and Mount Independence. The Americans abandoned and set on fire the block-houses and sawmills towards Lake George, with which the communications were now cut off.
