Ahead of him the band of Mohawks, old Hendrik on horseback at their head, marched steadily on, warily watching the woods and thickets for their enemies. They, at least, were in thorough keeping with the wildness of the scene, with their painted bodies, their fierce eyes and their glittering tomahawks. But around Robert and Tayoga were the young Philadelphians, trained, alert men now, and following them was the stream of New York and New England troops, strong, vigorous and alive with enthusiasm. The wilderness grew wilder and more dense, the Mohawks entering a great gorge, forested heavily, down the center of which flowed a brook of black water. Thickets spread everywhere, and there were extensive outcroppings of rock. At one point rose precipices, with the stony slopes of French Mountain towering beyond. At another point rose West Mountain, though it was not so high, but at all points nature was wild and menacing. The air seemed to Robert to grow darker, though he was not sure whether it was due to his imagination or to the closing in of the forests and mountains. At the same time a chill ran through his blood, a chill of alarm, and he knew instinctively that it was with good cause. "Look at the great sachem!" suddenly exclaimed Tayoga. Hendrik, loyal friend of the Americans and English, had reined in his horse, and his old eyes were peering into the thicket on his left, the mass of Mohawks behind him also stopping, because they knew their venerable leader would give no alarm in vain. Tayoga, Robert, Grosvenor and the Philadelphians stopped also, their eyes riveted on Hendrik. Robert's heart beat hard, and millions of motes danced in the air before his eyes. The sachem suddenly threw up one hand in warning, and with the other pulled back his horse. The next instant a single rifle cracked in the thicket, but in a few seconds it was followed by the crashing fire of hundreds. Many of the Mohawks fell, a terrible lane was cut through the ranks of the Colonials, and the bullets whistled about the heads of the Philadelphia troop. "The ambush!" cried Robert. "The ambush!" echoed the Philadelphians. Tayoga uttered a groan. His eyes had seen a sight they did not wish to see, however much he may have spoken of a glorious death for the old on the battlefield. Hendrik's horse had fallen beneath the leader, but the old chief leaped to his feet. Before he could turn a French soldier rushed up and killed him with a bayonet. Thus died a great and wise sachem, a devoted friend of the Americans, who had warned them in vain against marching into a trap, but who, nevertheless, in the very moment of his death, had saved them from going so completely into the trap that its last bar could close down.
