Cornwallis did not advance so rapidly as had been apprehended. After crossing the Catawba, he had to wait for his wagons and artillery, which had remained on the other side in the woods; so that by nightfall of the 1st of February he was not more than five miles on the road to Salisbury. Eager to come up with the Americans, he mounted some of the infantry upon the baggage horses, joined them to the cavalry, and sent the whole forward under General O'Hara. They arrived on the banks of the Yadkin at night, between the 2d and 3d of February, just in time to capture a few wagons lingering in the rear of the American army, which had passed. The riflemen who guarded them retreated after a short skirmish. There were no boats with which to cross; the Americans had secured them on the other side. The rain which had fallen throughout the day had overflooded the ford by which the American cavalry had passed. The pursuers were again brought to a stand. After some doubt and delay, Cornwallis took his course up the south side of the Yadkin, and crossed by what is still called the Shallow ford, while Greene continued on unmolested to Guilford Court-house, where he was joined by General Huger and his division on the 9th. Cornwallis was now encamped about twenty-five miles above them, at the old Moravian town of Salem.
The great object of Greene now was to get across the river Dan, and throw himself into Virginia. With the reinforcements and assistance he might there expect to find, he hoped to effect the salvation of the South, and prevent the dismemberment of the Union. The object of Cornwallis was to get between him and Virginia, force him to a combat before he could receive those reinforcements, or enclose him in between the great rivers on the west, the sea on the east, and the two divisions of the British army under himself and Lord Rawdon on the north and south. His lordship had been informed that the lower part of the Dan, at present, could only be crossed in boats, and that the country could not afford a sufficient number for the passage of Greene's army; he trusted, therefore, to cut him off from the upper part of the river, where alone it was fordable. Greene, however, had provided against such a contingency. Boats had been secured at various places by his agents, and could be collected at a few hours' notice at the lower ferries. Instead, therefore, of striving with his lordship for the upper fords, Greene shaped his course for Boyd's and Irwin's fords, just above the confluence of the Dan and Staunton rivers which forms the Roanoke, and about seventy miles from Guilford Court-house. This would give him twenty-five miles advantage of Lord Cornwallis at the outset. General Kosciuszko was sent with a party in advance to collect the boats and throw up breastworks at the ferries.
In ordering his march, General Greene took the lead with the main body, the baggage, and stores. General Morgan would have had the command of the rear-guard, but being disabled by a violent attack of ague and rheumatism, it was given to Colonel Otho H. Williams (formerly adjutant-general), who had with him Colonels Howard, Washington and Lee. This corps, detached some distance in the rear, did infinite service. Being lightly equipped, it could manoeuvre in front of the British line of march, break down bridges, sweep off provisions, and impede its progress, in a variety of ways, while the main body moved forward unmolested. It was now that Cornwallis most felt the severity of the blow he had received at the battle of the Cowpens in the loss of his light troops, having so few to cope with the élite corps under Williams.
We forbear to enter into the details of this masterly retreat, the many stratagems and manoeuvres of the covering party to delay and hoodwink the enemy. Tarleton himself bears witness, in his narrative, that every measure of the Americans was judiciously designed and vigorously executed. So much had Cornwallis been misinformed at the outset as to the means below of passing the river, that he pushed on in the firm conviction that he was driving the American army into a trap, and would give it a signal blow before it could cross the Dan.
In the meantime, Greene, with the main body, reached the banks of the river, and succeeded in crossing over with ease in the course of a single day at Boyd's and Irwin's ferries, sending back word to Williams, who with his covering party was far in the rear. That intelligent officer encamped, as usual, in the evening, at a wary distance in front of the enemy, but stole a march upon them after dark, leaving his camp fires burning. He pushed on all night, arrived at the ferry in the morning of the 15th, having marched forty miles within the last four and twenty hours; and made such despatch in crossing, that his last troops had landed on the Virginia shore by the time the astonished enemy arrived on the opposite bank.
For a day the two armies lay panting within sight of each other on the opposite banks of the river, which had put an end to the race. On the 16th, the river began to subside; the enemy might soon be able to cross. Greene prepared for a further retreat by sending forward his baggage on the road to Halifax, and securing the passage of the Staunton. At Halifax he was resolved to make a stand, rather than suffer the enemy to take possession of it without a struggle. Its situation on the Roanoke would make it a strong position for their army, supported by a fleet, and would favor their designs both on Virginia and the Carolinas. With a view to its defence, intrenchments had already been thrown up, under the direction of Kosciuszko.
Lord Cornwallis, however, did not deem it prudent, under present circumstances, to venture into Virginia, where Greene would be sure of powerful reinforcements. North Carolina was in a state of the utmost disorder and confusion; he thought it better to remain in it for a time, and profit by having compelled Greene to abandon it. After giving his troops a day's repose, therefore, he put them once more in motion on the 18th, along the road by which he had pursued Greene. This changed the game. Lee, with his legion, strengthened by two veteran Maryland companies, and Pickens, with a corps of South Carolina militia, all light troops, were transported across the Dan in the boats, with orders to gain the front of Cornwallis, hover as near as safety would permit, cut off his intercourse with the disaffected parts of the country, and check the rising of the royalists. Greene, in the meanwhile, remained with his main force on the northern bank of the Dan; waiting to ascertain his lordship's real designs, and ready to cross at a moment's warning.
The movements of Cornwallis, for a day or two, were of a dubious nature, designed to perplex his opponents; or the 20th, however, he took post at Hillsborough. Here he issued a proclamation, inviting all loyal subjects to assist in suppressing the remains of rebellion, and re-establishing good order and constitutional government. By another instrument, all who could raise independent companies were called upon to give in their names at head-quarters, and a bounty in money and lands was promised to those who should enlist under them. Tarleton was detached with the cavalry and a small body of infantry to a region of country lying between the Haw and Deep Rivers, to bring on a considerable number of loyalists who were said to be assembling there.
Rumor, in the meantime, had magnified the effect of his lordship's proclamations. Word was brought to Greene, that the tories were flocking from all quarters to the royal standard. Seven companies, it was said, had been raised in a single day. At this time the reinforcements to the American camp had been little more than six hundred Virginia militia, under General Stevens. Greene saw that at this rate, if Cornwallis was allowed to remain undisturbed, he would soon have complete command of North Carolina; he boldly determined, therefore, to recross the Dan at all hazards with the scanty force at his command, and give his lordship check. In this spirit he broke up his camp and crossed the river on the 23d.
In the meantime, Lee and Pickens, who were scouring the country about Hillsborough, received information of Tarleton's recruiting expedition. There was no foe they were more eager to cope with; and they resolved to give him a surprise. Having forded the Haw one day about noon, they learned that he was encamped about three miles off, that his horses were unsaddled, and that everything indicated confident security. They now pushed on under covert of the woods, prepared to give the bold partisan a blow after his own fashion. Before they reached the place, Tarleton had marched on. Being informed that he was to halt for the night at the distance of six miles, they still trusted to surprise him. On the way, however, they had an encounter with a body of three or four hundred mounted royalists, armed with rifles, and commanded by a Colonel Pyle, marching in quest of Tarleton. As Lee with his cavalry was in the advance, he was mistaken for Tarleton, and hailed with loyal acclamations. He favored the mistake, and was taking measures to capture the royalists, when some of them, seeing the infantry under Pickens, discovered their error and fired upon the rear-guard. The cavalry instantly charged upon them; ninety were cut down and slain, and a great number wounded; among the latter was Colonel Pyle himself, who took refuge among the thickets on the borders of a piece of water which still bears his name.
