From The Winning of the West, Vol. 3, by Theodore Roosevelt, published 1900, G.P. Putnam's Sons:
"Having reduced South Carolina to submission, the British commander [Ferguson] then threatened North Carolina; and Col. [Charles] McDowell, the commander of the whig militia in that district, sent across the mountains to the Holston men praying that they would come to his help. Though suffering continually from Indian ravages, and momentarily expecting a formidable inroad, they responded nobly to the call. Sevier remained to patrol the border and watch the Cherokees, while Isaac Shelby crossed the mountains with a couple of hundred mounted riflemen, early in July. The mountain men were joined by McDowell, with whom they found also a handful of Georgians and some South Carolinans; who when their States were subdued had fled northward, resolute to fight their oppressors to the last. The arrival of the mountain men put new life into the dispirited whigs."
