Carolina’s prestige was in eclipse, and another campaign was planned for 1761, led by Colonel James Grant, Virginia troops advancing, though leisurely,[i20] under Colonel Wm. Byrd III, to assist in the subjugation of the Cherokees in the Overhill towns. Adair’s _History_ indicates his connection with Grant’s expedition, but is barren of details and it has proven difficult to trace elsewhere the part he took. To the far-away Chickasaws, the trader turned to recoup his fortunes after the termination of the Cherokee War and his repulse in the matter of his second memorial. There was real need for Adair’s services on the part of that gallant people. The French were attempting to make a breach between them and the Choctaws. They were “in great want of ammunition” and goods.[i21] Adair chose Mobile as mart for his peltry, after the surrender of the country by the French under the peace treaty of 1763. Existing records testify to the fact that Adair aided the authorities in efforts to prevent the Chickasaws being debauched by rum and to hold unprincipled traders in leash. He supported the commissary of the government of West Florida, in February, 1766, in the arrest and prosecution of John Buckles and Alexander McIntosh, in a “Memorandum of some Material Heads,” in which his powers of invective did not fail to outcrop: McIntosh “debauched the Indians with rum to the uneasiness and disgust of orderly traders, the loss of their numerous outstanding debts and every chance of fair trade ... faithful to his black trust, in his Arabian-like method of plundering the Indians.... He would make a new Hell of this place, and it is hoped that he may go thru’ Purgatory properly.”[i22] It was during this stay (1761-68) among them that the greater portion of his _History of the American Indians_ was written. He left his oft-tried and true friends, the Chickasaws, in the early part of May, 1768,[i23] and went to the North—doubtless to interview Sir Wm. Johnson for materials with which to enlarge the scope of his work, his own experience and observations having been confined to the leading tribes of the South. Of Adair in London in 1775 we have not a glimpse. Did he visit Scotland and Ireland among his kinsmen?
