Running the Boundary Line

From A History of Watauga County, North Carolina, by John Preston Arthur, published 2002, Genealogical Publishing Company, page 120:

Running the State Line.— As the Cherokees occupied the territory southwest of the Big Pigeon River in what is now Haywood County, no provision was made for running the line beyond this point. Generally speaking, the line was to follow the tops of the Stone, the Smoky and the Unaka Mountains from Virginia to Georgia, but to be surveyed and marked only from Virginia to the Pigeon. The surveying party consisted of Col. Joseph McDowell, David Vance, Mussendine Matthews, speaker of the House, commissioners. John Strother and Robert Henry were the surveyors. The party met May 19, 1799, at Captain Isaac Weaver's, near what is now Tuckerdale, a station on the new Virginia-Carolina Railway, in Ashe County.

From the diary of John Strother, surveyor:

“25th [May 1799]. – We had a very disagreeable night the morning appears gloomy—some of our horses lost. Mr. Logan cut his foot; it will be bad. The horses were at length found. We all eat our breakfast & set out on the line, went ¾ mile. It set in and rained hard and obliged us to take up camp at the first place that offered, which was a branch of Roan’s Creek, where we spent an uncomfortable evening. The next day being the Lard’s day we spent it here in prayers for a plesant tour to ye Painted Rock. Genl McDowell left us this day. He is sick.”

Kings Mountain manuscripts, pre-Draper

From Western North Carolina: A History (1730-1913), by John Preston Arthur, published 1914, Edwards & Broughton, North Carolina, page 98:

"The white occupation of North Carolina had extended only to the Blue Ridge when the Revolution began;" but at its close General Charles McDowell, Col. David Vance and Private Robert Henry were among the first to cross the Blue Ridge and settle in the new county of Buncombe. As a reward for their services, no doubt, they were appointed to run and mark the line between North Carolina and Tennessee in 1799, McDowell and Vance as commissioners and Henry as surveyor. While on this work they wrote and left in the care of Robert Henry their narratives of the battle of Kings Mountain and the fight at Cowan's ford. After his death Robert Henry's son, William L. Henry, furnished the manuscript to the late Dr. J. F. E. Hardy, and he sent it to Dr. Lyman C. Draper, of Wisconsin. On it is largely based his 'King's Mountain and its Heroes' (1880)." 

The Call for the Overmountain Men

From King's Mountain and Its Heroes, by Lyman Copeland Draper, published 1881, P.G. Thomson, page 84:

When Colonel [Charles] McDowell became convinced that Ferguson's movement to the north-western portion of South Carolina, threatened the invasion of the North Province also, he not only promptly raised what force he could from the sparsely populated settlements, on the heads of Catawba, Broad and Pacolet rivers, to take post in the enemy's front and watch his operations; but dispatched a messenger with this alarming intelligence to Colonels John Sevier and Isaac Shelby, on Watauga and Holston, those over-mountain regions, then a portion of North Carolina, but now of East Tennessee; urging those noted border leaders to bring to his aid all the riflemen they could, and as soon as possible.
Sevier, unable to leave his frontier exposed to the inroads of the Cherokees, responded at once to the appeal, by sending a part of his regiment under Major Charles Robertson; and Shelby, being more remote, and having been absent on a surveying tour, was a few days later, but joined McDowell, at the head of two hundred mounted riflemen, about the twenty-fifth of July, at his camp near the Cherokee Ford of Broad river.

"... the transmontane men..."

From History of the McDowells and Connections, by John Hugh McDowell, pub. 1918, C. B. Johnston, pp. 234-235:

On the 29th of August, 1780, Colonel Ferguson moved into Troy (now Rutherford County) and camped, first at Gilberttown, three miles north of Rutherfordton, with the purpose of capturing Charles McDowell and destroying his command, and ultimately crossing into Washington and Sullivan counties (now Tennessee) and dealing with Shelby and Sevier of the Watauga settlement. Ferguson left Gilberttown with a detachment in search of Charles McDowell, but McDowell laid in ambush at Bedford Hill, on Crane [sic, Cane] Creek, and fired upon his forces while crossing the creek at Cowan's Ford. Major Dunlap was wounded and Ferguson was forced to retire to Gilberttown.
After this affair, Charles McDowell retreated across the mountains to warn Shelby and Sevier of the threatened desolation of their country, and to invite their co-operation in an attack on Ferguson. It was agreed that the transmontane men should be gathered as expeditiously as possible, while McDowell should send messengers to Colonels Cleveland and Hernando, of Wilkes County, and Major Joseph Winston, of Surrey. The energies of Shelby, of Sullivan and Sevier, of Washington County, N. C., then embracing the present State of Tennessee, were quickened by the message which Ferguson had released a prisoner to convey, to the effect that he would soon cross the mountains, hang the leaders and lay that country waste with fire and sword.
The clans were summoned to meet at Quaker Meadows on the 30th of September, 1780. Meantime Charles McDowell returned to watch Ferguson, protect cattle by assailing foraging parties, and give information to Shelby and Sevier of Ferguson's movements.
Rev. Samuel Doak invoked the blessings of God upon the Watauga men, as they left for King's Mountain to meet Ferguson, whose blasphemous boast had been that God Almighty could not drive him from his position. Those trustful old Scotchmen afterwards believed in their hearts that the hand of God was in the movement which cost him his life and destroyed his force.
