Wells had much conversation at this time with Tecumseh, who "openly and positively avowed his determination to resist the encroachments of the white people." Wells told the Shawnee chief that he would never be able to accomplish his designs, but Tecumseh replied that Wells would live to see the contrary. About this time a friendly Kickapoo chief arrived at Vincennes and told the Governor that he was determined to put him on his guard against the Prophet and his brother. "He said that their pacific professions were not to be relied upon; that he had heard them speaking to the Indians for several years and in that time he had never heard anything that they said but war and hatred against the United States. That the delivering up of the horses which were occasionally stolen was merely intended to lull our vigilance and to prevent us from discovering their designs until they were ripe for execution. That they frequently told their young men that they would defeat their plans by their precipitancy. That in their harangues to the Indians they frequently requested those who would not join their confederacy, to keep their secret. That they always promised them a rich harvest of plunder and scalps, declaring that the first stroke would put them in possession of an ample supply of arms, ammunition and provisions." On the second of May, General William Clark, of St. Louis, wrote to the Governor informing him that the Prophet had sent the belt to the Mississippi tribes, inviting them to join in a war against the United States, and declaring that the war would be begun by an attack on Vincennes. About the same time word was brought that the Sacs had acceded to the hostile confederacy, and that the Potawatomi in the region of Chicago were on the warpath. A party of surveyors employed by the surveyor-general to divide the New Purchase into townships, were seized and bound by a party of Weas, their arms taken from them, and the engineers driven in terror to Cincinnati. In the fore part of June, a pirogue sent up the Wabash with the annual supply of salt for the Indian tribes was seized by the Prophet and every barrel taken. The excuse given was, that the Prophet had two thousand warriors to feed, and that he had taken none on the previous year. Pierre La Plante, Harrison's agent at the Prophet's Town, reported that only about one hundred warriors were present at the time, but that Tecumseh was shortly expected to arrive with a considerable reinforcement from the lakes. About the twentieth of June, five Shawnees and ten Winnebagoes of the Prophet's party invaded Vincennes bringing a number of rifles and tomahawks to be repaired. They were boldly accused by some Potawatomi of Topenebee's faction to be meditating war against Harrison and to be making observations on the situation of affairs within the town.
