Baffled in this direction, the new commander-in-chief, General Gage, resolved to accomplish the desired end by an expedition from Fort Pitt. Pontiac, however, was known to be still plotting vengeance at that time, and it seemed advisable to break the way for the proposed expedition by a special mission to placate the Indians. For this delicate task Sir William Johnson selected a trader of long experience and of good standing among the western tribes, George Croghan. Notwithstanding many mishaps, the plan was carried out. With two boats and a considerable party of soldiers and friendly Delawares, Croghan left Fort Pitt in May, 1765. As he descended the Ohio he carefully plotted the river's windings and wrote out an interesting description of the fauna and flora observed. All went well until he reached the mouth of the Wabash. There the party was set upon by a band of Kickapoos, who killed half a dozen of his men. Fluent apologies were at once offered. They had made the attack, they explained, only because the French had reported that the Indians with Croghan's band were Cherokees, the Kickapoos' most deadly enemies. Now that their mistake was apparent, the artful emissaries declared, their regret was indeed deep. All of this was sheer pretense, and Croghan and his surviving followers were kept under close guard and were carried along with the Kickapoo band up the Wabash to Vincennes, where the trader encountered old Indian friends who soundly rebuked the captors for their inhospitality. Croghan knew the Indian nature too well to attempt to thwart the plans of his "hosts." Accordingly he went on with the band to the upper Wabash post Ouiatanon, where he received deputation after deputation from the neighboring tribes, smoked pipes of peace, made speeches, and shook hands with greasy warriors by the score. Here came a messenger from Saint-Ange asking him to proceed to Fort Chartres. Here, also, Pontiac met him, and, after being assured that the English had no intention of enslaving the natives, declared that he would no longer stand in the conquerors' path. Though in unexpected manner, Croghan's mission was accomplished, and, with many evidences of favor from the natives, he went on to Detroit and thence to Niagara, where he reported to Johnson that the situation in the West was ripe for the establishment of English sovereignty.
