"I think they're going to eat. Probably they've been rowing all the morning and are tired and hungry. They mean after that to go ahead with their main purpose, but we'll take 'em while they're eating. I hate to fire on anybody from ambush, but it's got to be done. There's no other way. We'll all lie close together here, and when the time comes to fire, I'll give the word."

The Indians sat on the ground after their fashion and began to eat cold food. Apparently they paid little attention to their prisoner, who stood near, and to whom they offered nothing. Why should he eat? He would never be hungry again. Nor need they watch him closely now. They had left a man with each of the boats, and even if he should run he could not escape them on the island.

Henry and Paul saw Mr. Pennypacker walk forward a few steps and look intently at the posts. Then he bowed his gray head and stood quite still. Both believed that he was praying. Water again rose in Paul's eyes and Henry's too were damp.

"Boys," whispered Henry, "I think the time has come. Take aim. We'll pick the four on the left, Sol the first on the end, the second for me, Tom the third and Paul the fourth. Now, boys, cock your rifles, and take aim, the best aim that you ever took in your life, and when I say 'Fire!' pull the trigger."

Every man from the covert did as he was directed. When Henry looked down the sights and picked out the right place on the broad chest of a warrior, he shuddered a little. He repeated to himself that he did not like it, this firing from ambush, but there was the old man, whom they loved, doomed to torture and the sacrifice. His heart hardened like flint and he cried "Fire!"

Four rifles flashed in the thicket. Two warriors fell without a sound. Two more leaped away, wounded, and all the others sprang to their feet with cries of surprise and alarm.

"Up and at 'em!" cried Henry in a tremendous voice. "Cut them to pieces!"

Drawing their pistols they rushed into the open space and charged upon the warriors, firing as they came.

The Indians were Wyandots, men who knew little of fear, but the surprise and the deadly nature of the attack was too much for them. Perhaps superstition also mingled with their emotions. Doubtless the spirits of the lake were angry with them for some cause, and the best thing they could do was to leave it as soon as they could. But one as he ran did not forget to poise his hatchet for a cast at the prisoner. The Reverend Silas Pennypacker would have seen his last sun that day had not Henry noticed the movement and quickly fired his pistol at the uplifted hand. The bullet pierced the Indian's palm, the tomahawk was dashed from his hand, and with a howl of pain he sped after the others who were flying for the boats.

Henry and his comrades did not pursue. They knew that they must act with all speed, as the Wyandots would quickly recover from their panic, and come back in a force that was still two to one. A single sweep of his knife and his old schoolmaster's arms were free. Then he shouted in the dazed man's ears:
