Henry looked back over his shoulder. The boat was blazing, but the light from it reached his comrades and himself. The Indians on the bank saw them. Hasty bullets began to flick the water near them. Canoes were already starting in chase.
"If that light keeps up, they're bound to git us," said Seth Cole.
"But it won't keep up," said Henry. "Swim, boys! Swim with all your might! It's not Indians alone that we've got to dodge!"
Tired as they were, they increased their speed by a supreme effort for a minute or so, and then as if by the same impulse all looked back. The boat was a mass of flame, a huge core of light, casting a brilliant reflection far out over the river and upon the bank, where trees, bushes, and warriors alike stood out in the red flare.
The boat seemed to quiver, and suddenly it leaped into the air. Then came a tremendous explosion and a gush of overpowering flame. Henry and his comrades dived instantly and swam as far as they could under water toward the eastern shore. When they came up again the flatboat and its terrible cannon were gone, heavy darkness again hung over land and water, and pieces of burning wood were falling with a hissing splash into the river. But they heard the voices of warriors calling to each other, organizing already for pursuit. Their expedition was a brilliant success, but Henry knew that it would be a hard task to regain Fort Prescott. Led by the renegades and driven on by their bitter chagrin, the Indians would swarm upon the river in their canoes, seeking for them everywhere with eyes used to darkness.
"Are you all here, boys?" he asked. He had been scorched on the shoulder by a burning fragment, but in the excitement he did not notice it. Two of the men were slightly wounded, but at that time they thought nothing of their hurts. All six were there, and at Henry's suggestion they dived again, floating down stream as long as they could hold their breath. When they came up again the six heads were somewhat scattered, but Henry called to them softly, and they swam close together again. Then they floated upon their backs and held a council of war.
"It seems likely to me," said Henry, "that the Indian canoes will go straight across the stream after us, naturally thinking that we'll make at once for Fort Prescott."
"I'm thinkin' that you're tellin' the truth," said Seth Cole.
"Then we must drop down the stream, strike the bank, and come back up in the brush to the place where our rifles and clothes are hid."
"Looks like the right thing to me," said Tom Wilmore. "I'll want my rifle back, but 'pears to me I'll want my clothes wuss. I'm a bashful man, I am. Look thar! they've got torches!"
