Chickasaw tribe. - The Chickasaw territory proper was in northern
Mississippi, at a considerable distance from the State under discussion,
but about 1753 a body of Chickasaw Indians settled on the South Carolina
side of Savannah River, to be near the English trading posts and to
keep in contact with the English, who were their allies. Before 1757
most of them moved over to the immediate neighborhood of Augusta and
remained there until the period of the American Revolution. In that
war they sided against the colonists and their lands were confiscated
in 1783. (See Chickasaw tribe of Mississippi.)
