Two days after the battle of Camden, the patriots, Shelby, Clarke and Williams, defeated a band of Tories at Musgrove's Mill in South Carolina; but hearing of the disaster at Camden, these officers now withdrew from the State. Sumter's corps, near Rocky Mount, had been put to flight by Tarleton, Gates had fled the State, and only Davie's men were left between the army of Cornwallis and Charlotte, North Carolina.
Had the British General pressed on into the State, North Carolina must have inevitably fallen into the hands of the enemy. But Cornwallis delayed the invasion for nearly a month, thus giving the Carolinians time to collect their forces to repel his attempt.
The General Assembly which met in September, 1780, acting upon Governor Nash's advice, created a Board of War to assist him in conducting the military affairs of the State. This board now proceeded to put General Smallwood, of Maryland, in command of all the forces in the State, giving him authority over all the officers in the Southern army, the honor being conferred upon him on account of his gallant conduct at Camden. General Gregory was consequently ordered to hold himself in readiness to obey General Smallwood's orders, with the other officers in North Carolina.
The Board of War then proceeded to raise money, arms and men for the army that would soon be called upon to drive Cornwallis from the State. Gregory's brigade received $25,000 of the funds raised, and 150 flints and 15 guns were distributed among his soldiers.
The British now confidently expected that Cornwallis would quickly subdue North Carolina, then sweep over the State into Virginia. In order to prevent the Americans from hurrying into that State to join forces against Cornwallis, General Leslie was ordered from New York to the Chesapeake, and in October his army was stationed near South Quays in Virginia, not far from Norfolk.
The presence of Leslie's army so close to the Carolina border caused much alarm for the safety of the Albemarle section, which for the second time was in danger of invasion. General Gregory, who after the battle of Camden had joined Exum and Jarvis in front of Cornwallis, had recently returned to Albemarle. He was now ordered to take the field against Leslie, and to prevent him from entering the State. From his camp at Great Swamp, near North River, he wrote to Governor Nash in November, 1780, reporting the repulse of the enemy. He also warned the Governor that the British were planning to attack Edenton; and he set forth in his letter the blow that the capture of this town would be to the commerce of the State.
General Gregory's post at Great Swamp was no sinecure. He had only about 100 men to withstand Leslie, whose forces at Portsmouth amounted to nearly 1,000 men. His troops were poorly equipped, half naked, and ill-fed; and his situation seemed almost desperate. To add to his troubles, an attempt was made at this time by Colonel Blount, of the Edenton District, to deprive him of his command. But a Council of State, held at Camp Norfleet Mills to inquire into the matter, declared that as Colonel Blount had resigned of his own free will and accord—in favor of Gregory—he should not now take the command from him.
In spite of the troubles and perplexities that beset Gregory in the fall of 1780, he bravely held his ground; and by the end of November he wrote Governor Nash from his camp at North West that the British had abandoned Portsmouth, and had departed for parts unknown.
While these events were taking place in the East, Cornwallis, whose left wing under Ferguson had suffered a crushing defeat at King's Mountain, disappointed at the humbling of the Tories at that battle, had left North Carolina on October 12th, and returned to South Carolina. The heavy rains encountered by his army on his retreat caused much sickness among his men; and himself falling ill, he was obliged to give up his command temporarily to Lord Rawdon.
General Leslie's destination soon became known. On November 23 he had abandoned the vicinity of Norfolk, and had sailed to Wilmington, N.C., hoping to rouse the Tories in that section; but Lord Rawdon's army being now in great danger, Leslie was ordered to his assistance, and he accordingly set out for the British army near Camden. But Southern Virginia and the Albemarle region were not long to be free from the fear of invasion, for soon another British army under the command of the traitor, Benedict Arnold, sailed into Chesapeake Bay, and Gregory was again sent to keep the enemy in check.
