upstream from it was the fact that he had a guide who had been slinking down this way since childhood. Even so, the last hundred feet to the river bank were nearly as frightening as the tumble on the ground under the dog's fangs. The rocks were wet and slimy, covered with spray as well as vegetation. Jake felt his foot give way, and only Busch's strong arms, grabbing Jake as he slid past, saved him.
'Don't fall,' whispered Busch. 'The rocks at the bottom are as sharp as ax heads.'
It seemed beyond belief that children would come this way, but then in innocence everyone is brave.
'It's much easier if you have small hands and feet,' said Busch, as if hearing Jake's thoughts. 'You can poke them into the crevices. Takes longer, though.'
The river was gently tickling the shoreline, eliciting a soft murmur from the rocks. Jake went slower and slower as his guide went faster and faster; the distance widened between them over the last twenty treacherous feet, and the disguised patriot reached bottom a full five minutes after his guide.
Bush was standing at the edge of the water. Just as Jake was about to apologize for taking so long, the captain waved his hand in front of his face and pointed out to the river. It was a moment or two before Jake could make out the shadow three-quarters of the way across.
It was a whaleboat, patrolling the water just north of the chain. The men inside were resting silently.
Busch and Jake stood like statues on the rocks for a minute that seemed like three hours. The night grew immeasurably colder in that time, dampness welling into the air. A fog began to form and the last hint of twilight disappeared. Jake's ears adjusted to the stillness so well he could hear the whispers of the soldiers in the boat, or thought he could; certainly he heard the order, 'All right then, back to the fort.' The oars slipped into the water and the shadow receded into the larger blackness.
'A last patrol as the sun finally sets,' noted Busch. 'Just before they light the watch fires, I suspect.' He started picking his way along the bank. 'That will be easy to time. Hold on to the tail of my coat. Be very careful.'
The rocks were slippery, but twisted trees and other brush gave them handholds, and they soon were within a hundred yards of the chain. The logs holding it up creaked continually, moaning under the weight of the iron and complaining of the tide. The chain itself creaked like hinges on a door, except that the sound was multiplied many times; the effect was something like a team of waterwheels might make, if built entirely of iron and made to operate at an excruciatingly slow speed, each squeak and creak amplified by a succession of paper tubes.
The chain links had been finished and placed in the water the previous November. At first, the current proved so strong that they snapped and were pulled downstream. Finally, the engineer for the project, Lieutenant Thomas Machin, realized that with certain slight modifications, the chain would hold if placed on a diagonal from its western terminus, in effect running with the strongest current.
It happened that Jake had met Machin in Boston a few years before; the lieutenant had been among the 'Indians' engaged in the famous tea party. Their acquaintanceship was extremely brief, and would not amount to much now — Machin was undoubtedly in a warm bed on the opposite shore, while Jake was starting to shiver with the cold on these rocks.
Busch stopped in front of him, and Jake realized he was studying something on the ground, unrelated to the chain.
'Come on,' he said finally, pulling off his coat. 'We shall see if the links are of equal strength and look for obstructions. We'll go out on the river.'
Before Jake could protest, Captain Busch took off his boots and dove into the river, aiming for the heavy chain and its log support bobbing a few leagues out in the water. He moved quickly, as if afraid to dwell along the shoreline.
Jake would have much preferred to stay there, but saw no way to do so without being branded a coward. It seemed foolhardy to swim out in the darkness and climb aboard a fitful line of wheezing rafts. Yet had he stopped and thought about it, he would have realized he'd done many less rational things in the name of Freedom — Jake quickly stripped to his breeches and shirt, leaving his guns in his boots. Armed only with the knife, which he tucked inside his belt, he got down on his hands and knees and half-stumbled, half-swam off the rocks toward the dark iron backbone of the Americans' river defense.
Three yards out and the water grabbed him with a sudden jolt, hurling him downstream at the obstruction.
'Keep your hands ahead of you,' shouted Busch, who'd already reached the chain. 'Use your hands on the logs.'
Easily said, but as strong as Jake was, he had trouble with the tricky eddy in the frigid water, just managing to get his arms up in front of his body as he hit the raft support about mid-chest. With a loud groan, he pulled himself onto the logs, grateful to get at least part of his body out of the sharp and icy current.
'Imagine the riptides further out,' said Busch, standing over him.
'Thanks, but I'll leave that to you.'
'Those must be the fire rafts,' Busch whispered, pointing across toward Fort Montgomery. The hulking log boats were framed in front of a series of sentry fires the night patrols had just lit to keep themselves warm by the chilly river.
'The fires make it difficult for them to see us,' said Busch. 'And besides, who would suspect that anyone had snuck out onto the river? We can rest here for a while. Look at how thick this chain is.'
'It seems very strong,' said Jake, sinking his hand down to feel around the iron. The metal pieces were just under two inches thick, folded into links. 'How are we going to break them?'
'We'll manage,' said Busch.
Jake thought of several possibilities — an explosive charge, a hammer and chisel, an immense file. Each had its difficulties — but none were impossible.
'At least the boom has not been constructed,' said Busch. 'Come, there was a float damaged further out a month ago; let's see if it has been repaired.'
As Jake followed into the vast hollow between the banks, his thoughts turned to increasing the chain's protection. The farmer's land could be occupied, and some way found to place a guard on the shoreline where they had descended. Instead of sending a rowboat out on a precursory inspection, several small boats would have to be posted on twenty-four-hour guard. A vessel should be stationed in the middle of the river, with lookouts on each side — and sharpshooters, too, so another mission such as this one would prove fatal.
The log rafts were spaced and constructed unevenly, so that even if they had not been shuddering back and forth, moving on them would have been haphazard at best. Nonetheless, Jake soon developed a method of proceeding that was a cross between crawling and swimming, and if it were not for the cold waves — while it was June, this water had originated high in the Catskill mountains weeks if not months before — he might have been tempted to enjoy his foray. The sensation of being nearly naked on the river, without boat or paddle, was like none he had experienced. He began to wonder if mermaids' calls to sailors might not be made out of their innocent bliss, for truly to float atop the water unfettered must seem like an ecstasy one could only wish to share with all around.
Busch had stopped ahead on a raft that had been used as a workman's station. He sat cross-legged with the water lapping at his thighs, as if he were some new species of waterborne Indian chief.
'There's a float just to our right that is missing some logs,' he said when Jake arrived. His voice seemed far away.
'Will we attack there?'
If Busch heard Jake's words, he did not acknowledge them. 'My sister died at the spot where we entered the water,' he answered instead. 'That is why my father became a madman.'
His voice had a distant quality that made it sound as if he were talking about something he had read, rather than lived.
'We came down here one night when my sister was thirteen. I was twelve. It was a brilliant harvest moon that night, and the water was warm. You would not know it from tonight, but the Hudson is often warm, most warm — you feel as if you are swimming in a bath.
'She slipped, and hit her head on the rocks. Her body came down all the way and fell into the river, but the current was not hard, and it washed up there, near where they have fastened the chain. If it were light we might even see the rock where I found her.
'I called for hours, hoping. When I found her body, I just… held her, hoping she would be alive, that it was a
