General Washington resolved in person to conduct the Virginia expedition. The troops under count Rochambeau, and strong detachments from the American army, amounting to more than two thousand men, and consisting of the light infantry, Lamb’s artillery, and several other corps, were destined for it. By the 25th of August the whole body, American and French, had crossed the North river. An intercepted letter of general Washington’s, in which he communicated, as the result of a consultation with the French commanders, the design to attack New York, had excited the apprehensions of the British general for the safety of that city. This apprehension was kept alive, and the real object of the Americans concealed, by preparations for an encampment in New Jersey, opposite to Staten island, by the route of the American army, and other appearances, indicating an intention to besiege New York; and the troops had passed the Delaware, out of reach of annoyance, before Sir Henry suspected their destination. General Washington pressed forward with the utmost expedition, and at Chester he received the important intelligence that count de Grasse had arrived with his fleet in the Chesapeake, and that the marquis St. Simon had, with a body of three thousand land forces, joined the marquis de la Fayette. Having directed the route of his army from the head of the Elk, he, accompanied by Rochambeau, Chatelleux, Du Portail, and Knox, proceeded to Virginia. They reached Williamsburg on the 14th of September, and immediately repaired on board the Ville de Paris, to settle with count de Grasse the plan of operations. The whole body of American and French troops reached Williamsburg by the 25th of September. At this place the allied forces were joined by a detachment of the militia of Virginia, under the command of governor Nelson, and preparations were soon made to attack the intrenchments of lord Cornwallis.

Yorktown, the head-quarters of lord Cornwallis, is a village on the south side of York river, the southern banks of which are high, and where ships of the line may ride in safety. Gloucester point is a piece of land on the opposite shore, projecting considerably into the river. Both these posts were occupied by the British; and a communication between them was commanded by their batteries, and by several ships of war. The main body of lord Cornwallis’ army was encamped on the open grounds about Yorktown, within a range of outer redoubts and field-works; and lieutenant-colonel Tarleton, with a detachment of six or seven hundred men, held the post at Gloucester point.

The legion of the duke de Lauzun, and a brigade of militia under general Weedon, the whole commanded by the French general De Choisé, were directed to watch and restrain the enemy on the side of Gloucester; andthe grand combined army, on the 30th of September, moved down to the investiture of Yorktown. On the night of the 6th of October, advancing to within six hundred yards of the English lines, they began their first parallel, and labored with such silence and diligence, that they were not discovered until morning, when the works they had raised were sufficient to protect them. On the 9th, several batteries being completed, a heavy cannonade was begun. Many of the British guns were dismounted, and portions of their fortifications laid level with the ground. On the night of the 11th, the besiegers commenced their second parallel, three hundred yards in advance of the first. This approach was made so much sooner than was expected, that the men were not discovered at their labor until they had rendered themselves secure from all molestation in front. The fire from the new batteries was still more furious and destructive. From two British redoubts, in advance of their main works, and flanking those of the besiegers, the men in the trenches were so severely annoyed, that Washington resolved to storm them.

The enterprise against one was committed to an American force under the marquis de la Fayette, that against the other to a French detachment. Colonel Hamilton, who led the van of the former, made such an impetuous attack that possession was soon obtained, with little slaughter. The French detachment was equally brave and successful, but sustained greater loss. On the 16th, a sortie was made from the garrison by a party of three hundred and fifty, commanded by lieutenant-colonel Abercrombie, who forced two batteries, and spiked eleven pieces of cannon; but the guards from the trenches immediately advancing on them, they retreated, and the pieces which they had hastily spiked were soon rendered fit for service. In the afternoon of the same day the besiegers opened several batteries in their second parallel; and in the whole line of batteries nearly one hundred pieces of heavy ordnance were now mounted. The works of the besieged were so universally in ruins as to be in no condition to sustain the fire which might be expected the next day. In this extremity, lord Cornwallis boldly resolved to attempt an escape by land with the greater part of his army. His plan was to cross over, in the night, to Gloucester point, and forcing his way through the troops under De Choisé, to pass through Maryland, Pennsylvania, and Jersey, and form a junction with the royal army at New York. In prosecution of this desperate design, one embarkation of his troops crossed over to the opposite point; but a violent storm of wind and rain dispersed the boats, and frustrated the scheme.

On the morning of the 17th the fire of the American batteries rendered the British post untenable. Lord Cornwallis, perceiving further resistance to be unavailing, about ten o’clock beat a parley, and proposed a cessation of hostilities for twenty-four hours, that commissioners might meet to settle the terms on which the posts of York and Gloucester should be surrendered. General Washington, in his answer, declared his ‘ardent desire to spare the effusion of blood, and his readiness to listen to such terms as were admissible;’ but to prevent loss of time, he desired ‘that, previous to the meeting of the commissioners, the proposals of his lordship might be transmitted in writing, for which purpose a suspension of hostilities for two hours should be granted.’ The terms proposed by his lordship were such as led the general to suppose that articles of capitulation might easily be adjusted, and he continued the cessation of hostilities until the next day.To expedite the business, he summarily stated the terms he was willing to grant, and informed earl Cornwallis, that if he admitted these as the basis of a treaty, commissioners might meet to put them into form. Accordingly, viscount de Noailles and lieutenant-colonel Laurens, on the part of the allies, and colonel Dundas and major Ross, on the part of the English, met the next day, and adjusted articles of capitulation, which were to be submitted to the consideration of the British general.

Resolving not to expose himself to any accident that might be the consequence of unnecessary delay, general Washington ordered the rough draft of the commissioners to be fairly transcribed, and sent to lord Cornwallis early next morning, with a letter expressing his expectation that the garrison would march out by two o’clock in the afternoon. Hopeless of more favorable terms, his lordship signed the capitulation, and surrendered the posts of York and Gloucester, with their garrisons, to general Washington; and the shipping in the harbor, with the seamen, to count de Grasse. The prisoners, exclusive of seamen, amounted to more than seven thousand, of which between four and five thousand only were fit for duty. The garrison lost, during the siege, six officers and five hundred and forty-eight privates, in killed and wounded. The privates, with a competent number of officers, were to remain in Virginia, Maryland, or Pennsylvania. The officers not required for this service were permitted on parole to return to Europe, or to any of the maritime posts of the English on the American continent. The terms granted to earl Cornwallis were, in general, the terms which had been granted to the Americans at the surrender of Charleston; and general Lincoln, who on that occasion resigned his sword to lord Cornwallis, was appointed to receive the submission of the royal army. The allied army, to which lord Cornwallis surrendered, amounted to sixteen thousand;—seven thousand French, five thousand five hundred continental troops, and three thousand five hundred militia. In the course of the siege they lost, in killed and wounded, about three hundred. The siege was prosecuted with so much military judgment and ardor, that the treaty was opened on the eleventh, and the capitulation signed on the thirteenth day after ground was broken before the British lines.

The capture of so large a British army excited universal joy, and on no occasion during the war did the Americans manifest greater exultation. From the nature and duration of the contest, the affections of many had been so concentrated upon their country, and so intense was their interest in its fate, that the news of this brilliant success produced the most rapturous emotions, under the operations of which, it is said, some were even deprived of their reason, and one aged patriot in Philadelphia expired.

The day after the capitulation general Washington ordered, ‘that those who were under arrest should be pardoned and set at liberty;’ and announced, that ‘divine service shall be performed to-morrow in the different brigades and divisions. The commander-in-chief recommends, that all the troops that are not upon duty do assist at it with a serious deportment, and that sensibility of heart which the recollection of the surprising and particular interposition of Providence in our favor claims.’ Congress, as soon as they received general Washington’s official letter giving information of the event, resolved to go in procession to the Dutch Lutheran church, and return thanks to Almighty God for the signal success of the American arms; and they issued a proclamation, recommending to the citizens of theUnited States to observe the 13th of December as a day of public thanksgiving and prayer.

While these successful operations had been carrying on in Virginia, Sir Henry Clinton endeavored, if possible, to recall Washington, or at least to divert his attention, by some daring enterprise in the north. Giving to the traitor Arnold, who had just returned from his destructive expedition to Virginia, the command of a strong detachment, he sent him against New London, a flourishing city situated upon the river Thames, in his native state. Nearly opposite, on a hill in Groton, stood fort Griswold, which was then garrisoned by militia, hastily summoned from their labors in the field. Against this fort Arnold despatched a part of his troops. It was assaulted on three sides at the same moment. The garrison, fighting in view of their property and their homes, made a brave and obstinate resistance. By their steady and well-directed fire many of the assailants were killed. Pressing forward with persevering ardor, the British entered the fort through the embrasures. Immediately all resistance ceased. Irritated by gallantry which should have caused admiration, a British officer inquired who commanded the fort. ‘I did,’ said colonel Ledyard, ‘but you do now;’ and presented him his sword. He seized it, and, with savage cruelty, plunged it into his bosom. This was the signal for an indiscriminate massacre. Of a hundred and sixty men, composing the garrison, all but forty were killed or wounded, and most of them after resistance had ceased. Seldom has the glory of victory been tarnished by such detestable barbarity. The British then entered New London, which was set on fire and consumed. The property destroyed was of immense value. Perceiving no other object within the reach of his force, Arnold led back his troops to New York.

A circumstance which evidently exercised a very favorable influence on American affairs during this period should not be omitted—the institution of a national bank. The plan of it was projected by Robert Morris, one of the delegates of Pennsylvania, a man of high reputation, and well versed in affairs of commerce and finance, whom congress had appointed treasurer. He assigned to this bank a capital of four hundred thousand dollars, divided in shares of four hundred dollars each, in money of gold or silver, to be procured by subscriptions. Twelve directors were to manage the bank, which was denominated by congress, ‘The President, Directors, and Company of the Bank of North America.’ To the financial skill and indefatigable efforts of Mr. Morris in the treasury department, it has been thought our country was scarcely less indebted, than to the valor of her soldiers and the wisdom of her statesmen. Under his auspices, public credit revived; the army was pacified; and a new impulse given to every operation in the field and the cabinet.
