George Croghan organized and led the Ohio Confederation at Logstown, which Pennsylvania recognized as independent of the Six Nations, and appointed him its colonial agent a few days before Celeron's 1749 expedition reached Logstown. Croghan purchased 200,000 acres from the Iroquois, later learning that the deeds would be void if in Pennsylvania. With Andrew Montour, he guided Virginia's Ohio Company scout Christopher Gist in 1750 and arranged his 1752 Logstown treaty. Pennsylvania's plans for a fort at the forks of the Ohio had been abandoned in 1751 when Montour testified that the Indians did not want it. Virginia's 1754 stockade was commanded by Croghan's business partner William Trent and surrendered by his brother Edward Ward. As a captain in charge of the Indians under Col. Washington, then under Gen. Braddock, Croghan could do little to capture Fort Duquesne, but as William Johnson's deputy Indian agent in 1758 he hurried from facilitating the Easton Treaty to his Indian scouts. At the head of Gen. Forbes' column in its fall campaign, he worked with Col. Bouquet and built the first Lawrenceville Croghan Hall. After it was burnt during Pontiac's Rebellion, Croghan brought Pontiac to Detroit in 1765 and, except for the Shawnees during Dunmore's War, kept the Ohio tribes pacified thereafter.
