On the 15th of June General Rutherford marched within two miles of Charlotte. Here he learned that Lord Rawdon had retrograded from the Waxhaws to Camden. He then resolved to advance on the Tories, who, it was well known, had assembled in strong force at Ramsour's Mill, near the present town of Lincolnton. Having issued orders on the 14th to Colonel Francis Locke, Captains Falls and Brandon, of Rowan, and to Major David Wilson, of Mecklenburg, and to other officers, to raise men and attack this body of Tories, he marched on the 18th eleven miles, to Tuckasege Ford, on the Catawba River. He sent an express on the same day to Colonel Locke to meet him with his forces three miles north-west of the river, at Colonel Dickson's plantation. The express, for some unknown reason, never reached Colonel Locke. This officer, failing to secure the co-operative aid of General Rutherford, marched from Mountain Creek late on the evening of the 19th of June, and early on the morning of the 20th attacked and routed the Tories before the arrival of General Rutherford's forces. (For further particulars, see the "Battle of Ramsour's Mill," under the head of Lincoln County.)

After the battle of Ramsour's Mill, General Rutherford marched against the Tories assembled under Colonel Bryan in the forks of Yadkin River, while Major Davie was ordered to move with his mounted force and take position near the South Carolina line, to protect this exposed frontier from the incursions of the British and the Tories. He accordingly took position on the north side of Waxhaw Creek, where he was joined by Major Crawford, with a few South Carolina troops and thirty-five Indian warriors of the Catawba tribe, under their chief, New River, and the Mecklenburg militia under Colonel Hagins.

On the 20th of July Major Davie surprised and captured at Flat Rock, a convoy of provisions, spirits and clothing, guarded by some dragoons and volunteers, on their way to the post at Hanging Rock, about four and a half miles distant. The capture was effected without loss; the spirits, provisions and wagons were destroyed, and the prisoners, mounted on the captured horses and guarded by dragoons under Captain William Polk, at dark commenced their retreat. On Beaver Creek, about midnight, they were attacked by the enemy in ambuscade, concealed under the fence in a field of standing corn. The rear guard had entered the lane when Captain Petit, the officer in advance, hailed the British in their place of concealment. A second challenge was answered by a volley of musketry from the enemy, which commenced on the right, and passed by a running fire to the rear of the detachment. Major Davie rode rapidly forward and ordered the men to push through the lane; but, under surprise, his troops turned back, and upon the loaded arms of the enemy. He was thus compelled to repass the ambuscade under a heavy fire, and overtook his men retreating by the same road they had advanced. The detachment was finally rallied and halted upon a hill, but so discomfited at this unexpected attack that no effort could induce them to charge upon the enemy.

A judicious retreat was the only course left to avoid a similar disaster, which was effected; and Major Davie, having passed the enemy's patrols, regained his camp early on the next day without further accident. In this attack, the fire of the enemy fell chiefly upon those in the lane, who were prisoners (confined two on a horse with the guard). These were nearly all killed, or severely wounded. Of the Whigs, Lieutenant Elliott was killed, and Captain Petit, who had been sent in advance by Major Davie to examine the lane, the ford of the creek and the houses, and failing to do so, as carefully as was proper, paid the penalty of neglect of duty by being wounded with two of his men. Major Davie, who was noted for his vigilance, anticipated some attempt by the British and Tories to recover the prisoners, and had taken, as he believed, all necessary precautions to prevent a surprise or ambuscade.

Major Davie, in a manuscript account of this affair, now on file in the archives of the Historical Society at Chapel Hill, leaves this judicious advice:

"It furnishes a lesson to officers of partisan corps, that every officer of a detachment may, at some time, have its safety and reputation committed to him, and that the slightest neglect of duty is generally severely punished by an enemy."

Rocky Mount is on the west bank of the Wateree River (as the Catawba is called after its junction with Wateree Creek), thirty miles from Camden, and was garrisoned by Colonel Turnbull with one hundred and fifty New York volunteers and some militia. Its defences consisted of two log-houses, a loop-holed building and an abattis.[J]

On the 30th of July, 1780, General Sumter and Colonel Neal, from South Carolina, and Colonel Irwin, with three hundred Mecklenburg militia, joined Major Davie. A council was held, and it was determined that simultaneous attacks should be made upon the British posts at Rocky Mount and Hanging Rock. General Sumter was accompanied by Colonels Neal, Irwin and Lacy, and Captain McLure, and some of his kinsmen, the Gastons. Having; crossed the Catawba at Blair's Ford, he arrived early on the next day, and made vigorous attacks against the fort, but failed in capturing it, mainly for the want of artillery. The attack elicited the praise of even the enemy. Early in the action, the gallant Colonel Neal was killed, with five whites and one Catawba Indian, and many were severely wounded. The British loss was ten killed, and the same number wounded. General Sumter ordered a retreat, which was effected without further annoyance or loss.

Major Davie, with about forty mounted riflemen, and the same number of dragoons, and some Mecklenburg militia, under Colonel Hagins, approached Hanging Rock on the same day. While he was reconnoitering the ground, previous to making the attack, he was informed that three companies of Bryan's Tory regiment, returning from a foraging expedition, were encamped at a farmhouse near the post.

Major Davie, with his brave associates, immediately fell upon them with vigor, both in front and rear, and all but a few of them were either killed or wounded. No time could be spared to take prisoners, as the engagement at the farm-house was in full view of the British post at Hanging Rock. The fruits of this victory were sixty valuable horses, and one hundred muskets and rifles. The whole camp of the enemy instantly beat to arms, but this brilliant affair was ended, and Davie out of reach before the enemy's forces were in motion, or their consternation subsided from this daring and successful attack. Major Davie reached his camp safely without the loss of a single man.
