Sir Henry Clinton, on the other hand, had to construct batteries on Long Island, to oppose those of Thompson, and cover the passage of his troops by boats or by the ford. Thus time was consumed, and the enemy were, from the 1st to the 28th of June, preparing for the attack.
At length on the 28th of June, the Thunder Bomb commenced the attack, throwing shells at the fort as the fleet, under Sir Peter Parker, advanced. About eleven o'clock the ships dropped their anchors directly before the front battery. ["They commenced," says Lee, "the most furious fire I ever saw." The garrison, however, according to British authority, stuck with the greatest constancy and firmness to their guns; fired deliberately and slow, and took a cool, effective aim. The ships suffered accordingly, they were torn almost to pieces, and the slaughter was dreadful. The fire from the ships did not produce the expected effect.] The fortifications were low, composed of earth and palmetto wood, which is soft, and makes no splinters, and the merlons were extremely thick. At one time there was a considerable pause in the American fire, and the enemy thought the fort was abandoned. It was only because the powder was exhausted. As soon as a supply could be forwarded from the mainland by General Lee, the fort resumed its fire with still more deadly effect. Through unskilful pilotage, several of the ships ran aground, where one, the frigate Actæon, remained; the rest were extricated with difficulty. Those which bore the brunt of the action were much cut up. One hundred and seventy-five men were killed, and nearly as many wounded. Sir Henry Clinton, with two thousand troops and five or six hundred seamen, attempted repeatedly to cross from Long Island, and co-operate in the attack upon the fort, but was as often foiled by Colonel Thompson, with his battery of two cannons, and a body of South Carolina rangers and North Carolina regulars.
The combat slackened before sunset, and ceased before ten o'clock. Sir Peter Parker, who had received a severe contusion in the engagement, then slipped his cables, and drew off his shattered ships to Five Fathom Hole. The Actæon remained aground. On the following morning Sir Henry Clinton made another attempt to cross from Long Island to Sullivan's Island; but was again repulsed, and obliged to take shelter behind his breastworks. Sir Peter Parker, too, giving up all hope of reducing the fort in the shattered condition of his ships, ordered that the Actæon should be set on fire and abandoned. Within a few days the troops were re-embarked from Long Island: the attempt upon Charleston was for the present abandoned, and the fleet once more put to sea.
In this action, one of the severest in the whole course of the war, the loss of the Americans in killed and wounded was but thirty-five men. Colonel Moultrie derived the greatest glory from the defence of Sullivan's Island; though the thanks of Congress were voted as well to General Lee, Colonel Thompson and those under their command.
The tidings of this signal repulse of the enemy came most opportunely to Washington, when he was apprehending an attack upon New York.
General Putnam, beside his bravery in the field, was somewhat of a mechanical projector. The batteries at Fort Washington had proved ineffectual in opposing the passage of hostile ships up the Hudson. He was now engaged on a plan for obstructing the channel opposite the fort, so as to prevent the passing of any more ships. A letter from him to General Gales (July 26th) explains his project. "We are preparing chevaux-de-frise, at which we make great despatch by the help of ships, which are to be sunk. The two ships' sterns lie towards each other, about seventy feet apart. Three large logs, which reach from ship to ship, are fastened to them. The two ships and logs stop the river two hundred and eighty feet. The ships are to be sunk, and when hauled down on one side, the pricks will be raised to a proper height, and they must inevitably stop the river, if the enemy will let us sink them."
It so happened that one Ephraim Anderson, adjutant to the second Jersey battalion, had recently submitted a project to Congress for destroying the enemy's fleet in the harbor of New York. He had attempted an enterprise of the kind against the British ships in the harbor of Quebec during the siege, and, according to his own account, would have succeeded, had not the enemy discovered his intentions, and stretched a cable across the mouth of the harbor, and had he not accidentally been much burnt. His scheme was favorably entertained by Congress, and Washington, by a letter dated July 10th, was instructed to aid him in carrying it into effect. Anderson, accordingly, was soon at work at New York constructing fire-ships, with which the fleet was to be attacked. Simultaneous with the attack, a descent was to be made on the British camp on Staten Island, from the nearest point of the Jersey shore, by troops from Mercer's flying camp, and by others stationed at Bergen under Major Knowlton, Putnam's favorite officer for daring enterprises. Projectors are subject to disappointments. It was impossible to construct a sufficient number of fire-ships and galleys in time. The flying camp, too, recruited but slowly, and scarcely exceeded three thousand men; the combined attack by fire and sword had therefore to be given up.
In the course of a few days arrived a hundred sail, with large reinforcements, among which were one thousand Hessians, and as many more were reported to be on the way. The troops were disembarked on Staten Island, and fortifications thrown up on some of the most commanding hills. All projects of attack upon the enemy were now out of the question. Indeed, some of Washington's ablest advisers questioned the policy of remaining in New York, where they might be entrapped as the British had been in Boston.
During the latter part of July, and the early part of August, ships of war with their tenders continued to arrive, and Scotch Highlanders, Hessians, and other troops to be landed on Staten Island. At the beginning of August, the squadron with Sir Henry Clinton, recently repulsed at Charleston, anchored in the bay.
In the meantime, Putnam's contrivances for obstructing the channel had reached their destined place. A letter, dated Fort Washington, August 3d, says: "Four ships, chained and boomed, with a number of amazing large chevaux-de-frise, were sunk close by the fort under command of General Mifflin, which fort mounts thirty-two pieces of heavy cannon. We are thoroughly sanguine that they (the ships up the river) never will be able to join the British fleet, nor assistance from the fleet be afforded to them." Another letter, written at the same date from Tarrytown, on the borders of the Tappan Sea, gives an account of an attack made by six row galleys upon the Phoenix and the Rose. They fought bravely for two hours, hulling the ships repeatedly, but sustaining great damage in return; until their commodore, Colonel Tupper, gave the signal to draw off.
The force of the enemy collected in the neighborhood of New York was about thirty thousand men; that of the Americans a little more than seventeen thousand, but was subsequently increased to twenty thousand, for the most part, raw and undisciplined. One-fourth were on the sick list with bilious and putrid fevers and dysentery; others were absent on furlough or command; the rest had to be distributed over posts and stations fifteen miles apart.
Washington kept the most watchful eye upon the movements of the enemy. Beside their great superiority in point of numbers as well as discipline, to his own crude and scanty legions, they possessed a vast advantage in their fleet. "They would not be half the enemy they are," observed Colonel Reed, "if they were once separated from their ships." Every arrival and departure of these, therefore, was a subject of speculation and conjecture. Aaron Burr, at that time in New York, aide-de-camp to General Putnam, speaks in a letter to an uncle, of thirty transports, which, under convoy of three frigates, had put to sea on the 7th of August, with the intention of sailing round Long Island and coming through the Sound, and thus investing the city by the North and East Rivers. "They are then to land on both sides of the island," writes he, "join their forces, and draw a line across, which will hem us in, and totally cut off all communication; after which, they will have their own fun."
In this emergency, Washington wrote to General Mercer for 2,000 men from the flying camp. Colonel Smallwood's battalion was immediately furnished, as a part of them. The Convention of the State ordered out hasty levies of country militia, to form temporary camps on the shore of the Sound, and on that of the Hudson above King's Bridge,
