The ships of war which caused this alarm and turmoil, lay quietly anchored in the broad expanses of the Tappan Sea and Haverstraw Bay; shifting their ground occasionally, and keeping out of musket shot of the shore, apparently sleeping in the summer sunshine, with awnings stretched above their decks; while their boats were out taking soundings quite up to the Highlands, evidently preparing for further operations. At night, too, their barges were heard rowing up and down the river on mysterious errands; perriaugers, also, paid them furtive visits occasionally; it was surmised, with communications and supplies from tories on shore. While the ships were anchored in Haverstraw Bay, one of the tenders stood into the Bay of Peekskill, and beat up within long shot of Fort Montgomery, where General George Clinton was ensconced with six hundred of the militia of Orange and Ulster counties. As the tender approached, a thirty-two pounder was brought to range upon her. The ball passed through her quarter; whereupon she put about, and ran round the point of the Donderberg, where the boat landed, plundered a solitary house at the foot of the mountain, and left it in flames. The marauders, on their way back to the ships, were severely galled by rustic marksmen, from a neighboring promontory. The ships, now acquainted with the channel, moved up within six miles of Fort Montgomery. General Clinton apprehended they might mean to take advantage of a dark night, and slip by him in the deep shadows of the mountains. The shores were high and bold, the river was deep, the navigation of course safe and easy. Once above the Highlands, they might ravage the country beyond, and destroy certain vessels of war which were being constructed at Poughkeepsie. To prevent this, he stationed a guard at night on the furthest point in view, about two miles and a half below the fort, prepared to kindle a blazing fire should the ships appear in sight. Large piles of dry brushwood mixed with combustibles, were prepared at various places up and down the shore opposite to the fort, and men stationed to set fire to them as soon as a signal should be given from the lower point. The fort, therefore, while it remained in darkness, would have a fair chance with its batteries as the ships passed between it and these conflagrations. A private committee sent up by the New York Convention, had a conference with the general, to devise further means of obstructing the passage of ships up the river. Fire rafts were to be brought from Poughkeepsie and kept at hand ready for action. These were to be lashed two together, with chains, between old sloops filled with combustibles, and sent down with a strong wind and tide, to drive upon the ships. An iron chain, also, was to be stretched obliquely across the river from Fort Montgomery to the foot of Anthony’s Nose, thus, as it were, chaining up the gate of the Highlands.
