Reliable word came to the Governor in April that the Prophet had assembled one thousand souls at the Prophet's Town, with probably three hundred fifty or four hundred men among them, consisting principally of Kickapoos and Winnebagoes, "but with a considerable number of Potawatomis and Shawnees and a few Chippewas and Ottawas;" that the French traders along the Wabash had been warned by the Prophet's followers to separate themselves from the Americans at Vincennes for trouble was brewing; that the Indians at Tippecanoe had refused to buy ammunition of the traders, saying that they had a plenty, and could get plenty more without paying for it; that Matthew Elliott, the British agent at Malden, was busy with plot and intrigue against the United States. But Harrison was surrounded by some of the best scouts and confidential agents that a frontier official ever commanded--among them Touissant Dubois, Joseph Barron and Michael Brouillette. He kept awake and on the alert. Tecumseh now assumed a more active leadership. The day had arrived for the statesman and warrior to sound the alarm, form an active league and confederacy of all the tribes, and with tomahawk in hand, resist any further advancement on the part of the whites. As Harrison afterwards remarked, he appeared today on the Wabash, a short time later on the shores of Lake Erie or Lake Michigan, and then upon the Mississippi. Everywhere he was masterful, eloquent, convincing, and "made an impression favorable to his purpose." At one time during the early summer it is known that he was at Detroit, and he was probably in close communication with his British allies, although he professed to hate them. About May, 1810, a council of all the tribes of the Wabash and those to the north was called at the river St. Joseph of Lake Michigan. The whole situation was fraught with danger, for Harrison had reason to believe that many of the tribes had already received the tomahawk and were meditating a combined attack on the settlements. Subsequent events proved that his fears were well founded. He immediately dispatched John Conner to the Delawares and "pointed out to them the unavoidable destruction which awaited all the tribes which should dare to take up the hatchet against their fathers, and the great danger that the friendly tribes would incur, if war should be kindled, from the difficulty of discriminating friend from foe."
