In July 1782 a meeting took place at the Shawnee villages near the headwaters of the Mad River in the Ohio Country, with Shawnees, Delawares, Mingos, Wyandots, Miamis, Ottawas, Ojibwas, and Potawatomis in attendance. As a result, 150 British rangers under Captain William Caldwell (of Butler's Rangers) and some 1,100 Indian warriors supervised by Pennsylvania Loyalists Alexander McKee, Simon Girty, and Matthew Elliott set out to attack Wheeling, on the upper Ohio River. This was one of the largest forces sent against American settlements during the war.
