After all, Lee and Pickens missed the object of their enterprise. The approach of night and the fatigue of their troops, made them defer their attack upon Tarleton until morning. In the meantime, the latter had received an express from Cornwallis, informing him that Greene had passed the Dan, and ordering him to return to Hillsborough as soon as possible. He hastened to obey. Lee with his legion was in the saddle before daybreak; but Tarleton's troops were already on the march. Before sunrise, he had forded the Haw, and "Light-horse Harry" gave over the pursuit.
The re-appearance of Greene and his army in North Carolina, heralded by the scourings of Lee and Pickens, disconcerted the schemes of Lord Cornwallis. The recruiting service was interrupted. Many royalists, who were on the way to his camp, returned home. Forage and provisions became scarce in the neighborhood. He found himself, he said, "amongst timid friends and adjoining to inveterate rebels." On the 26th, therefore, he abandoned Hillsborough, threw himself across the Haw, and encamped near Alamance Creek, one of its principal tributaries, in a country favorable to supplies and with a tory population. His position was commanding, at the point of concurrence of roads from Salisbury, Guilford, High Rockford, Cross Creek, and Hillsborough. It covered also the communication with Wilmington, where a dépôt of military stores, so important to his half-destitute army, had recently been established.
Greene with his main army took post about fifteen miles above him, on the heights between Troublesome Creek and Reedy Fork, one of the tributaries of the Haw. His plan was to cut the enemy off from the upper counties; to harass him by skirmishes, but to avoid a general battle; thus gaining time for the arrival of reinforcements daily expected.
On the 6th of March, Cornwallis, learning that the light troops under Williams were very carelessly posted, put his army suddenly in motion, and crossed the Alamance in a thick fog; with the design to beat up their quarters, drive them in upon the main army, and bring Greene to action should he come to their assistance. His movement was discovered by the American patrols, and the alarm given. Williams hastily called in his detachments, and retreated with his light troops across Reedy Fork, while Lee with his legion manoeuvred in front of the enemy. A stand was made by the Americans at Wetzell's Mill, but they were obliged to retire with the loss of fifty killed and wounded. Cornwallis did not pursue; evening was approaching, and he had failed in his main object; that of bringing Greene to action. The latter, fixed in his resolve of avoiding a conflict, had retreated across the Haw.
Greene's long-expected reinforcements now arrived, having been hurried on by forced marches. They consisted of a brigade of Virginia militia, under General Lawson, two brigades of North Carolina militia, under Generals Butler and Eaton, and four hundred regulars, enlisted for eighteen months. His whole effective force, according to official returns, amounted to four thousand two hundred and forty-three foot, and one hundred and sixty-one cavalry. Of his infantry, not quite two thousand were regulars, and of these, three-fourths were new levies. His force nearly doubled in number that of Cornwallis, which did not exceed two thousand four hundred men; but many of Greene's troops were raw and inexperienced, and had never been in battle; those of the enemy were veterans, schooled in warfare. Greene knew the inferiority of his troops in this respect; his reinforcements, too, fell far short of what he had been led to expect, yet he determined to accept the battle which had so long been offered. All detachments were ordered to assemble at Guilford, within eight miles of the enemy, where he encamped on the 14th, sending his wagons and heavy baggage to the Iron Works at Troublesome Creek, ten miles in his rear.
Cornwallis sent his carriages and baggage to Bell's Mills, on Deep River, and set out at daybreak on the 15th for Guilford. Within four miles of that place, near the New Garden Meeting-house, Tarleton with the advanced guard came upon the American advance-guard, composed of Lee's partisan legion, and some mountaineers and Virginia militia. Tarleton and Lee were well matched in military prowess, and the skirmish between them was severe. Lee's horses, being from Virginia and Pennsylvania, were superior in weight and strength to those of his opponent, which had been chiefly taken from plantations in South Carolina. The latter were borne down by a charge in close column. Tarleton, seeing that his weakly-mounted men fought to a disadvantage, sounded a retreat; Lee endeavored to cut him off. A general conflict of the vanguards, horse and foot, ensued, when the appearance of the main body of the enemy obliged Lee, in his turn, to retire with precipitation.
During this time, Greene was preparing for action on a woody eminence, a little more than a mile south of Guilford Court-house. The neighboring country was covered with forest, excepting some cultivated fields about the court-house, and along the Salisbury road, which passed through the centre of the place, from south to north. He had drawn out his troops in three lines. The first, composed of North Carolina militia, volunteers and riflemen, under Generals Butler and Eaton, was posted behind a fence, with an open field in front, and woods on the flanks and in the rear. About three hundred yards behind this, was the second line, composed of Virginia militia, under Generals Stevens and Lawson, drawn up across the road, and covered by a wood. The third line, about four hundred yards in the rear of the second, was composed of Continental troops or regulars; those of Virginia under General Huger on the right, those of Maryland under Colonel Williams on the left. Colonel Washington with a body of dragoons, Kirkwood's Delaware infantry, and a battalion of Virginia militia covered the right flank; Lee's legion, with the Virginia riflemen under Colonel Campbell, covered the left. Two six-pounders were in the road, in advance of the first line; two field-pieces with the rear-line near the court-house, where General Greene took his station.
About noon the head of the British army was descried advancing spiritedly from the south along the Salisbury road, and defiling into the fields. A cannonade was opened from the two six-pounders, in front of the first American line. It was answered by the British artillery. Neither produced much effect. The enemy now advanced coolly and steadily in three columns; the Hessians and Highlanders under General Leslie on the right, the Royal artillery and guards in the centre, and Webster's brigade on the left. The North Carolinians, who formed the first line, waited until the enemy were within one hundred and fifty yards, when, agitated by their martial array and undaunted movement, they began to fall into confusion; some fired off their pieces without taking aim; others threw them down, and took to flight. A volley from the foe, a shout, and a charge of the bayonet, completed their discomfiture. Some fled to the woods, others fell back upon the Virginians, who formed the second line. General Stevens, who commanded the latter, ordered his men to open and let the fugitives pass, pretending that they had orders to retire. Under his spirited command and example, the Virginians kept their ground and fought bravely.
The action became much broken up and diversified by the extent of the ground. The thickness of the woods impeded the movements of the cavalry. The reserves on both sides were called up. The British bayonet again succeeded; the second line gave way, and General Stevens, who had kept the field for some time, after being wounded in the thigh by a musket-ball, ordered a retreat. The enemy pressed with increasing ardor against the third line, composed of Continental troops, and supported by Colonel Washington's dragoons and Kirkwood's Delawares. Greene counted on these to retrieve the day. They were regulars; they were fresh, and in perfect order. He rode along the line, calling on them to stand firm, and give the enemy a warm reception.
The first Maryland regiment which was on the right wing, was attacked by Colonel Webster, with the British left. It stood the shock bravely, and being seconded by some Virginia troops, and Kirkwood's Delawares, drove Webster across a ravine. The second Maryland regiment was not so successful. Impetuously attacked by Colonel Stewart, with a battalion of the guards and a company of grenadiers, it faltered, gave way and fled, abandoning two field-pieces, which were seized by the enemy. Stewart was pursuing, when the first regiment which had driven Webster across the ravine, came to the rescue with fixed bayonets, while Colonel Washington spurred up with his cavalry. The fight now was fierce and bloody. Stewart was slain; the two field-pieces were retaken, and the enemy in their turn gave way and were pursued with slaughter; a destructive fire of grape-shot from the enemy's artillery checked the pursuit. Two regiments approached on the right and left; Webster recrossed the ravine and fell upon Kirkwood's Delawares. There was intrepid fighting in different parts of the field; but Greene saw that the day was lost; there was no retrieving the effect produced by the first flight of the North Carolinians. Unwilling to risk the utter destruction of his army, he directed a retreat, which was made in good order, but they had to leave their artillery on the field, most of the horses having been killed. About three miles from the field of action he made a halt to collect stragglers, and then continued on to the place of rendezvous at Speedwell's Iron Works on Troublesome Creek. The British were too much cut up and fatigued to follow up their victory. Two regiments, with Tarleton's cavalry, attempted a pursuit, but were called back.
