Unlike most mountaineers the Cherokees were not held to be very formidable fighters, when compared with their fellows of the lowlands.[8] In 1760 and 1761 they had waged a fierce war with the whites, had ravaged the Carolina borders, had captured British forts, and successfully withstood British armies; but though they had held their own in the field, it had been at the cost of ruinous losses. Since that period they had been engaged in long wars with the Chickasaws and Creeks, and had been worsted by both. Moreover, they had been much harassed by the northern Indians. So they were steadily declining in power and numbers.[9] Though divided linguistically into two races, speaking different dialects, the Otari and Erati, the political divisions did not follow the lines of language. There were three groups of towns, the Upper, Lower, and Middle; and these groups often acted independently of one another. The Upper towns lay for the most part on the Western Waters, as they were called by the Americans,--the streams running into the Tennessee. Their inhabitants were known as Overhill Cherokees and were chiefly Otari; but the towns were none of them permanent, and sometimes shifted their positions, even changing from one group to another. The Lower towns, inhabited by the Erati, lay in the flat lands of upper Georgia and South Carolina, and were the least important. The third group, larger than either of the others and lying among the hills and mountains between them, consisted of the Middle towns. Its borders were ill-marked and were ever shifting. Thus the towns of the Cherokees stretched from the high upland region, where rise the loftiest mountains of eastern America, to the warm, level, low country, the land of the cypress and the long-leaved pine. Each village stood by itself, in some fertile river-bottom, with around it apple orchards and fields of maize. Like the other southern Indians, the Cherokees were more industrious than their northern neighbors, lived by tillage and agriculture as much as by hunting, and kept horses, hogs, and poultry. The oblong, story-high houses were made of peeled logs, morticed into each other and plastered with clay; while the roof was of chestnut bark or of big shingles. Near to each stood a small cabin, partly dug out of the ground, and in consequence very warm; to this the inmates retired in winter, for they were sensitive to cold. In the centre of each village stood the great council-house or rotunda, capable of containing the whole population; it was often thirty feet high, and sometimes stood on a raised mound of earth.[10]
