The fortress was invested upon three sides: up the precipitous westward slope swarmed the Senacas and Cayugas; the fan-shaped body of the Onondagas advanced from the east, where the ground was broken; eastward and westerly on the valley side, where the attackers hoped to strike the victorious blow, the confederate bands of the Mohawks and Oneidas lay hidden, awaiting the signal which had been agreed upon. The river occupied the line to the south, and between its banks and the enemy ambushed in the valley an outlet was left in order that the French might be given the opportunity of vacating their position. Once in open country, they might be broken up into bands and hunted down. The attack from west and north had been arranged to draw the French from the one point where the fortress was vulnerable. It appeared as though the besieged were tumbling blindfold into the trap, which a general of experience would have at once suspected. Every fighting-man in the fortress assembled to hold the almost impregnable heights. In the absence of the leader this mistake was pardonable. There the noise of battle was terrific. The wild light of the bush fire beyond the river flung its shadows over the grass hill and cast into detail figures and flashing tomahawks. A storm of hissing arrows swept over the rocks. The bronze-skinned warriors rushed up and climbed the heights. The bravest of the Senacas, that hardy fighting race of the highlands, were already within the fortress, tomahawking the gunners with hideous yells. The man-of-war was useless. Boats were let down, and the sailors flung ropes round the ends of the logs which supported the fire-raft, and towed the flaming peril away. Then the clumsy ship blundered up stream, only to find herself helplessly cut off from the enemy by the sheer wall of rock. She drifted back, and the master gave the order for the guns to be beached and dragged up the slope to strengthen the resources of the besieged. "'Fore Heaven!" cried Van Vuren. "The natives win!" The Dutchmen had perforce returned to watch the progress of the assault. They saw the Cayugas dealing blows against the summit, repulsed, but never actually losing ground. Each assault found the height invested more strongly by the overwhelming host. Similar success attended the ascent of the Onondagas. The rival factions swayed upon the distant summit, lit by the fire of the cannon. The Dutchmen hovered in uncertainty, until the opposition yielded and the Indians began to burn the huts which looked down upon the river. At this signal a shout went up from the valley, and the Mohawks and Oneidas rushed out to complete the work. At the same time Van Vuren gave the word, and the big men re-crossed the river, gained the level, and joined the sachems and doctors who were dancing and screaming at the foot of the hill.
