WASHINGTON AT WHITE MARSH—MEASURES TO CUT OFF THE ENEMY’S SUPPLIES—THE FORTS ON THE DELAWARE REINFORCED—COLONEL GREENE OF RHODE ISLAND AT FORT MERCER—ATTACK AND DEFENCE OF THAT FORT—DEATH OF COUNT DONOP.
Washington remained a few days at Perkiomen Creek, to give his army time to rest, and recover from the disorder incident to a retreat. Having been reinforced by the arrival of twelve hundred Rhode Island troops from Peekskill, under General Varnum, and nearly a thousand Virginia, Maryland, and Pennsylvania troops, he gradually drew nearer to Philadelphia, and took a strong position at White Marsh, within fourteen miles of that city. By a resolution of Congress, all persons taken within thirty miles of any place occupied by British troops, in the act of conveying supplies to them, were subjected to martial law. Acting under the resolution, Washington detached large bodies of militia to scour the roads above the city, and between the Schuylkill and Chester, to intercept all supplies going to the enemy.
On the forts and obstructions in the river, Washington mainly counted to complete the harassment of Philadelphia. These defences had been materially impaired. The works at Billingsport had been attacked and destroyed, and some of the enemy’s ships had forced their way through the chevaux-de-frise placed there. The American frigate Delaware, stationed in the river between the upper forts and Philadelphia, had run aground before a British battery, and been captured.
It was now the great object of the Howes to reduce and destroy, and of Washington to defend and maintain, the remaining forts and obstructions. Fort Mifflin, which we have already mentioned, was erected on a low, green, reedy island in the Delaware, a few miles below Philadelphia, and below the mouth of the Schuylkill. It consisted of a strong redoubt, with extensive outworks and batteries. There was but a narrow channel between the island and the Pennsylvania shore. The main channel, practicable for ships, was on the other side. In this were sunk strong chevaux-de-frise, difficult either to be weighed or cut through, and dangerous to any ships that might run against them; subjected as they would be to the batteries of Fort Mifflin on one side, and on the other to those of Fort Mercer, a strong work at Red Bank on the Jersey shore.
Fort Mifflin was garrisoned by troops of the Maryland line, under Lieutenant-colonel Samuel Smith of Baltimore; and had kept up a brave defence against batteries erected by the enemy on the Pennsylvania shore. A reinforcement of Virginia troops made the garrison between three and four hundred strong.
Floating batteries, galleys, and fire-ships, commanded by Commodore Hazelwood, were stationed under the forts and about the river.
Fort Mercer had hitherto been garrisoned by militia, but Washington now replaced them by four hundred of General Varnum’s Rhode Island Continentals. Colonel Christopher Greene was put in command; a brave officer who had accompanied Arnold in his rough expedition to Canada, and fought valiantly under the walls of Quebec. “The post with which you are intrusted,” writes Washington in his letter of instructions, “is of the utmost importance to America. The whole defence of the Delaware depends upon it; and consequently all the enemy’s hopes of keeping Philadelphia, and finally succeeding in the present campaign.”
Colonel Greene was accompanied by Captain Mauduit Duplessis, who was to have the direction of the artillery. He was a young French engineer of great merit, who had volunteered in the American cause, and received a commission from Congress. The chevaux-de-frise in the river had been constructed under his superintendence.
Greene, aided by Duplessis, made all haste to put Fort Mercer in a state of defence; but before the outworks were completed, he was surprised (October 22) by the appearance of a large force emerging from a wood within cannon shot of the fort. Their uniforms showed them to be Hessians. They were, in fact, four battalions twelve hundred strong of grenadiers, picked men, beside light-infantry and chasseurs, all commanded by Count Donop, who had figured in the last year’s campaign.
Colonel Greene, in nowise dismayed by the superiority of the enemy, forming in glistening array before the wood, prepared for a stout resistance. In a little while an officer was descried, riding slowly up with a flag, accompanied by a drummer. Greene ordered his men to keep out of sight, that the fort might appear but slightly garrisoned.
When within proper distance, the drummer sounded a parley, and the officer summoned the garrison to surrender; with a threat of no quarter in case of resistance.
Greene’s reply was, that the post would be defended to the last extremity.
The flag rode back and made report. Forthwith the Hessians were seen at work throwing up a battery within half a mile of the outworks. It was finished by four o’clock, and opened a heavy cannonade, under cover of which the enemy were preparing to approach.
As the American outworks were but half finished, and were too extensive to be manned by the garrison, it was determined by Greene and Duplessis that the troops should make but a short stand there; to gall the enemy in their approach, and then retire within the redoubt, which was defended by a deep intrenchment, boarded and fraised.
Donop led on his troops in gallant style, under cover of a heavy fire from his battery. They advanced in two columns, to attack the outworks in two places. As they advanced, they were excessively galled by a flanking fire from the American galleys and batteries, and by sharp volleys from the outworks. The latter, however, as had been concerted, were quickly abandoned by the garrison. The enemy entered at two places, and, imagining the day their own, the two columns pushed on with shouts to storm different parts of the redoubt. As yet, no troops were to be seen; but as one of the columns approached the redoubt on the north side, a tremendous discharge of grape shot and musketry burst forth from the embrasures in front, and a half-masked battery on the left. The slaughter was prodigious; the column was driven back in confusion. Count Donop, with the other column, in attempting the south side of the redoubt, had passed the abatis; some of his men had traversed the fosse; others had clambered over the pickets, when a similar tempest of artillery and musketry burst upon them. Some were killed on the spot, many were wounded, and the rest were driven out. Donop himself was wounded, and remained on the spot; Lieutenant-colonel Mingerode, the second in command, was also dangerously wounded. Several other of the best officers were slain or disabled. Lieutenant-colonel Linsing, the oldest remaining officer endeavored to draw off the troops in good order, but in vain; they retreated in confusion, hotly pursued, and were again cut up in their retreat by the flanking fire from the galleys and floating batteries.
The loss of the enemy in killed and wounded, in this brief but severe action, was about four hundred men. That of the Americans, eight killed and twenty-nine wounded.
As Captain Mauduit Duplessis was traversing the scene of slaughter after the repulse, he was accosted by a voice from among the slain: “Whoever you are, draw me hence.” It was the unfortunate Count Donop. Duplessis had him conveyed to a house near the fort, where every attention was paid to his comfort. He languished for three days, during which Duplessis was continually at his bedside. “This is finishing a noble career early,” said the count sadly, as he found his death approaching,—then, as if conscious of the degrading service in which he had fallen, hired out by his prince to aid a foreign power in quelling the brave struggle of a people for their liberty, and contrasting it with that in which the chivalrous youth by his bedside was engaged—“I die,” added he bitterly, “the victim of my ambition, and of the avarice of my sovereign.”[97] He was but thirty-seven years of age at the time of his death.
According to the plan of the enemy, Fort Mifflin, opposite to Fort Mercer, was to have been attacked at the same time by water. The force employed was the Augusta of sixty-four guns; the Roebuck of forty-four, two frigates, the Merlin sloop of eighteen guns, and a galley. They forced their way through the lower line of chevaux-de-frise; but the Augusta and Merlin ran aground below the second line, and every effort to get them off proved fruitless. To divert attention from their situation, the other vessels drew as near to Fort Mifflin as they could, and opened a cannonade; but the obstructions in the river had so altered the channel that they could not get within very effective distance. They kept up a fire upon the fort throughout the evening, and recommenced it early in the morning, as did likewise the British batteries on the Pennsylvania shore; hoping that under cover of it the ships might be got off. A strong adverse wind, however, kept the tide from rising sufficiently to float them.
The Americans discovered their situation, and sent down four fire-ships to destroy them, but without effect. A heavy fire was now opened upon them from the galleys and floating batteries. It was warmly returned. In the course of the action, a red-hot shot set the Augusta on fire. It was impossible to check the flames. All haste was made with boats to save the crew, while the other ships drew off as fast as possible to get out of the reach of the explosion. She blew up, however, while the second lieutenant, the chaplain, the gunner, and several of the crew were yet on board, most of whom perished. The Merlin was now set on fire and abandoned; the Roebuck and the other vessels dropped down the river, and the attack on Fort Mifflin was given up.
These signal repulses of the enemy had an animating effect on the public mind, and were promptly noticed by Congress. Colonel Greene, who commanded at Fort Mercer, Lieutenant-colonel Smith of Maryland, who commanded at Fort Mifflin, and Commodore Hazelwood, who commanded the galleys, received the thanks of that body; and subsequently, a sword was voted to each, as a testimonial of distinguished merit.
