While these disputes as to the government of the new communities were in progress an additional danger threatened the pioneers. For a whole year the British had been plying the various Indian tribes from the lakes to the gulf with presents, supplies, and ammunition. In the Northwest bounties had actually been offered for American scalps. During the spring of 1776 plans were concerted, chiefly through Stuart and Cameron, British agents among the Southern Indians, for uniting the Loyalists and the Indians in a crushing attack upon the Tennessee settlements and the back country of North Carolina. Already the frontier of South Carolina had passed through the horrors of Indian uprising; and warning of the approaching invasion had been mercifully sent the Holston settlers by Atta-kulla-kulla's niece, Nancy Ward, the "Pocahontas of the West"--doubtless through the influence of her daughter, who loved Joseph Martin. The settlers, flocking for refuge into their small stockaded forts, waited in readiness for the dreaded Indian attacks, which were made by two forces totaling some seven hundred warriors. On July 20th, warned in advance of the approach of the Indians, the borderers, one hundred and seventy in all, marched in two columns from the rude breastwork, hastily thrown up at Eaton's Station, to meet the Indians, double their own number, led by The Dragging Canoe. The scouts surprised one party of Indians, hastily poured in a deadly fire, and rushed upon them with such impetuous fury that they fled precipitately. Withdrawing now toward their breastwork, in anticipation of encountering there a larger force, the backwoodsmen suddenly found themselves attacked in their rear and in grave danger of being surrounded. Extending their own line under the direction of Captain James Shelby, the frontiersmen steadily met the bold attack of the Indians, who, mistaking the rapid extension of the line for a movement to retreat, incautiously made a headlong onslaught upon the whites, giving the war-whoop and shouting: "The Unakas are running!" In the ensuing hot conflict at close quarters, in some places hand to hand, the Indians were utterly routed--The Dragging Canoe being shot down, many warriors wounded, and thirteen left dead upon the field.
