After leaving New Jersey, Davie began to study law in
Salisbury, North Carolina, under Spruce Macay (pronounced "
Muh-coy"), who would later provide Andrew Jackson with legal training. In December 1778, Davie left Salisbury to join 1,200 militiamen led by
Brigadier General Allen Jones of
Northampton County, NC. Jones's force advanced toward
Charleston, South Carolina, intending to aid the port city as it prepared its defenses against possible British assault. That threat receded, so Davie and the rest of Jones's men returned to North Carolina after marching as far south as
Camden, South Carolina. After briefly resuming his studies in Salisbury, Davie closed his law books again in the spring of 1779 to re-enter military service. This time, though, Davie did not volunteer for an existing force; he helped to raise and train a local cavalry troop. For his work in forming "a Company of Horses in the
District of Salisbury," he received a lieutenant's commission in April from North Carolina Governor
Richard Caswell. Davie did not remain in that junior rank for long. In May 1779, he and his company were attached to the legion of General
Casimir Pułaski, who moved from Pennsylvania to South Carolina earlier in the year to help bolster American positions in and around Charleston. Promoted to the rank of
major under Pulaski, Davie assumed command of a brigade of cavalry. On June 20, 1779, just two days shy of his twenty-third birthday, Davie led a charge against British forces at the
Battle of Stono Ferry outside Charleston. He suffered a serious wound to his thigh in that engagement, fell from his horse, and narrowly escaped capture. While convalescing from his injuries, Davie resumed his legal studies in Salisbury. The citizenry presented him with an honorary sword for his exemplary conduct and courage. Soon he completed or "stood" his examinations and, in November 1779, obtained a license to practice law in South Carolina. In the late spring and summer of the following year, Davie, now fully recovered, formed an independent cavalry company again. He led that mounted force in several actions during the summer of 1780. Shortly after the
Battle of Hanging Rock, Davie received word of a new army moving into South Carolina under General
Horatio Gates. Gates was soundly defeated at the
Battle of Camden on August 16, 1780. While the Continentals fought hard, his militia largely fled without much, if any, of a fight. Gates and what remained of his army fell back into North Carolina. Davie narrowly missed the battle. Instead of retreating north along with Gates and the remnants of the American army, Davie moved south towards the enemy and Camden to recover supply wagons and gather intelligence on enemy movements. In the time between Camden and the Battle of Kings Mountain, in October 1780, Davie's cavalry was the only unbroken corps between the British army and what was left of the Continental forces. Davie's most audacious action as a cavalry officer came at the
Battle of Charlotte on September 26, 1780. Ordered to cover the American army retreat and hinder the British invasion of North Carolina, Davie, now a
colonel, and 150 of his mounted militia set up a defense in what was then the small village of
Charlotte, North Carolina. He dismounted several of his men and had them take station behind a stone wall at the summit of a hill in the center of town. Other dismounted soldiers were scattered on the flanks with a reserve of cavalry. At about noon, the British army under General
Lord Cornwallis appeared. Cornwallis' forces numbered at least 2,000
Redcoats and
loyalists. After three charges of British cavalry and infantry moving on his right flank, Davie and his men retreated northward. Cornwallis subsequently occupied Charlotte, but he remained there less than two weeks, withdrawing his forces from the "hornets' nest" after receiving news of the defeat of Loyalist forces by backcountry militia at the
Battle of Kings Mountain on October 7, 1780. As Cornwallis's army marched back toward South Carolina, Davie directed his men to shadow and skirmish with enemy units and to disrupt and intercept their communications. Davie's military service in the Revolution changed dramatically after December 1780, when General
Nathanael Greene arrived in North Carolina to take command of the American army in the "Southern Department". Headquartered in Charlotte, Greene desperately needed more provisions and equipment for his soldiers as he prepared to counter the inevitable return of Cornwallis to North Carolina. Davie's leadership skills and knowledge of the region's terrain and inhabitants impressed Greene. In January 1781, he persuaded the experienced cavalry officer to relinquish his field command to serve as the army's commissary-general. In that position, Davie spent the final stages of the war carrying out the crucial but often thankless tasks of locating, organizing, and transporting supplies, often using his funds for General Greene's ever-needy troops and North Carolina's militia. During the Revolutionary War, he was with the North Carolina militia and State troops from 1780 to 1782. He was a Lieutenant, Captain, and Major in South Carolina and North Carolina militias. On September 5, 1780, he was selected as commander of the newly created NC State Cavalry-Western District. On January 16, 1781, he was appointed by the Board of War as Commissary General for the State per request of
Maj. Gen. Nathanael Greene, replacing Col. Thomas Polk, who had resigned. On February 13, 1781, the North Carolina General Assembly confirmed this position officially, which was eliminated in May 1782. He was at the Battle of Wahab's Plantation in South Carolina and the
Battle of Charlotte. • Lieutenant in the
