The defeat of Davidson opened the passage of the river. All the American parties retreated, and on the same day the rest of the British army crossed at Beattie's ford. Tarleton, with the cavalry and the Twenty-third regiment, was sent in pursuit of the militia, and being informed on his march that the neighboring militia were assembling at Tarrant's tavern, about ten miles distant, he hastened with the cavalry to that place. About 500 militia were assembled and seemed not unprepared to receive him. He attacked them with his usual impetuosity and soon defeated and dispersed them with considerable slaughter. The passage of the river and the total discomfiture of the party at Tarrant's tavern so much intimidated the inhabitants of the country that the royal army received no further trouble from the militia till it had passed the Yadkin.

A grand military race now began between the retreating Americans under Greene and the pursuing British under Cornwallis. Greene marched so rapidly that he passed the Yadkin at the trading ford on the night between the 2d and 3d of February (1781), partly by fording and partly by means of boats and flats. So closely was he pursued that the British van was often in sight of the American rear and a sharp conflict happened not far from the ford, between a body of American riflemen and the advanced guard of the British army, when the latter obtained possession of a few wagons. Greene secured all the boats on the south side and here it again happened as at the Catawba—the river suddenly rose by reason of the preceding rains and the British were unable to pass. This second escape by the swelling of the waters was interpreted by the Americans as a visible interposition of Heaven in their behalf and inspired then with a lofty enthusiasm in that cause which seemed to be the peculiar care of Omnipotence.

Greene, released from the immediate pressure of his pursuers, continued his march northward and on the 7th of February joined his division under Huger and Williams near Guilford Courthouse.

In order to cover his retreat and to check the pursuing enemy Greene formed a light corps out of Lee's legion, Howard's infantry, Washington's cavalry, and some Virginia riflemen under Major Campbell, amounting to 700 men, the flower of the southern army. As General Morgan was severely indisposed the command of these light troops was given to Col. Otho Holland Williams, formerly adjutant-general.

Having refreshed his troops, and made the necessary arrangements on the morning of the 10th of February (1781), Greene left Guilford Courthouse on his march towards the Dan, and was pursued by Cornwallis, who had been detained by the long circuit which he was obliged to make in order to pass the Yadkin. The retreat and pursuit were equally rapid, but the boldness and activity of the American light troops compelled the British to march compactly and with caution, for on one occasion Colonel Lee charged the advanced cavalry of the British army suddenly and furiously, killed a number, and made some prisoners. On this occasion Cornwallis felt the loss of the light troops who had been killed or taken at the Cowpens. He was destined to regret their loss through the rest of the campaign.

Greene's precautions and preparations for passing the Dan were successful and on the 14th of February he crossed that river at Boyd's and Irwin's ferries with his army, baggage, and stores. Although his light troops had marched forty miles that day, yet the last of them had scarcely reached the northern bank when the advanced guard of the British army appeared on the other side of the river.

The escape of Greene into Virginia without a battle and without any loss except a few wagons at the Yadkin, was a severe disappointment to Cornwallis. He had entirely failed in his attempts against Greene, but he was consoled by the reflection that he had completely driven him out of North Carolina, and that now there was nothing to hinder the loyal inhabitants from openly espousing the British cause and reinforcing the royal army.

Cornwallis now gave up the pursuit and repaired to Hillsborough with the view of calling out and organizing the Royalist forces. His adherents, though here particularly strong, did not come forward to the extent expected. The larger portion, as elsewhere, regarded the cause with that passive and inert attachment which we have remarked to be generally prevalent and even the more zealous having suffered severely by former premature displays, dreaded lest the republican cause should regain the ascendancy. The view also of the distress and exhaustion of the British troops after so long a march was by no means alluring. Yet seven companies were formed and detachments began to come in from different quarters.

On the other hand, Greene, having obtained a reinforcement of Virginia militia, repassed the Dan and with his light troops endeavored to annoy the British army and prevent recruiting. Major Lee surprised a detachment of Royalists who mistook him for Tarleton and cut them nearly to pieces. On account of the exhausted state of the country at Hillsborough, Cornwallis soon withdrew to a position on the Allimance creek between Haw and Deep rivers, where he could be better supplied and support his friends who were numerous there. Greene, however, by an active use of his cavalry and light troops, severely harassed his opponent and by changing his own position every night, eluded the attempt to bring him to an engagement.

At length General Greene, having received reinforcements which raised his army to above 4,200 men, of whom about a third were regulars, determined to offer battle. This was what Cornwallis had eagerly sought, yet his own effective force being reduced to somewhat under 2,000 he felt now some hesitation, and probably would have acted more wisely in maintaining the defensive. Even the enterprising Tarleton observes that in his circumstances defeat would have been total ruin, while any victory he might expect to gain could yield little fruit. All the habits and views of Cornwallis, however, being directed to an active campaign, he formed his resolution and, on the 15th of March (1781), proceeded to the attack. Greene had drawn up his army very judiciously near Guilford Courthouse mostly on a range of hills covered with trees and brushwood.
