Tecumseh's oratory was called into play again in the autumn of 1807, when the Americans were thrown into a state of terror by the murder of a white man near the site of the present town of Urbana. This deed of violence, coupled with the constant increase of the Prophet's band at Greenville, caused the wildest alarm among the settlers. Tecumseh and his brother disclaimed all knowledge of the murder, which had been committed by some wandering Indians, and they agreed to attend a council at Springfield to reassure the whites. The Indians who attended the council were asked to lay aside their arms. Tecumseh haughtily refused, thinking it unbecoming the dignity of a warrior chief. When the request was repeated, the wily Indian replied that his tomahawk was also his pipe and that he might wish to smoke. Thereupon a gaunt American advanced and offered Tecumseh his own pipe. Taking the earthen bowl with its long stern into his fingers, Tecumseh eyed it curiously; his gaze then travelled to the owner, who stood half fearful of the result of this offer. Then with an indignant gesture the chief tossed the pipe into the bushes behind him. Nothing more was said about the tomahawk.

The council was held in the shade of spreading maples. The chiefs and their warriors ranged themselves in a semicircle on the grass. The pipe of peace slowly made its round in token of goodwill. Several chiefs spoke in turn, expressing the pacific intentions of the Indians. Tecumseh referred to the recent murder, and denied that it had been the act of any of the tribes under his influence. He explained that the motive for the gathering of so many red men at Greenville was purely religious, and that all were friendly towards the whites. His wards and manner again carried conviction, and the council terminated peacefully.

The Americans, however, still continued to regard the Prophet's settlement at Greenville as a real menace. During the same autumn came another message to all the tribes under the Prophet's influence from the governor of the territory of Indiana, William Henry Harrison, afterwards president of the United States, and an active and successful leader of the Americans in the War of 1812. The message closed with these words:

My children, I have heard bad news. The sacred spot where the great council fire was kindled, around which the Seventeen Fires and ten tribes of their children smoked the pipe of peace—that very spot, where the Great Spirit saw His red and white children encircle themselves with the chain of friendship,—that place has been selected for dark and bloody councils. My children, this business must be stopped. You have called in a number of men from the most distant tribes, to listen to a fool, who speaks not the words of the Great Spirit, but those of the devil and of the British agents. My children, your conduct has much alarmed the white settlers near you. They desire that you will send away those people, and if they desire to have the impostor with them, they may carry him. Let him go to the lakes; he can hear the British more distinctly.

Tecumseh was absent from Greenville when this message was received, and it fell to the Prophet to make a reply. He was sorry, he said, that his father listened to the advice of bad birds. He denied that the Indians had any intercourse with the British, or that they desired anything but peace and to hear the words of the Great Spirit.

Early in the spring of 1808 Tecumseh and the Prophet, with their band of followers, left Greenville and set out in a westerly direction, across what is now the state of Indiana. Land had been granted to them by the Potawatomis and Kickapoos on the banks of the Tippecanoe, near its junction with the Wabash, and here they intended to make a new town, which should be the headquarters of their proposed confederacy. No more desirable spot could have been chosen. It was almost central in relation to the tribes they were endeavouring to bring together, and it had convenient communication with Lake Erie by means of the Wabash and Maumee rivers, and with Lake Michigan and the Illinois country by way of the Tippecanoe and other connecting waters. On one side an almost impenetrable stretch of wilderness formed a natural defence. From this position, also, Tecumseh was able to watch carefully the country from which he wished to exclude white settlers.

The Prophet's influence soon extended Among the neighbouring tribes, and the American authorities again became alarmed, the more so as they learned that among his followers warlike sports were now being practised along with religious rites. To counteract the effect of such reports the Prophet sent a message to Governor Harrison to say that he had been misrepresented, and followed it up by a personal visit along with a number of his followers, to explain his attitude towards the Americans. The visit lasted for a fortnight and frequent conferences took place between Harrison and the Prophet. The governor also questioned many of the Indians, but could learn nothing from them derogatory to their leader. Desiring to know to what extent the Prophet's teachings controlled his followers, he tempted them with liquor, but they remained true to their vow of total abstinence.

Before taking his leave Tenskwatawa thus addressed himself to the governor:

I told all the redskins, that the way they were in was not good, and that they ought to abandon it. That we ought to consider ourselves as one man; but we ought to live agreeably to our several customs, the red people after their mode, and the white people after theirs; particularly that they should not drink whisky; … do not take up the tomahawk should it be offered by the British, or by the Long Knives; do not meddle with anything that does not belong to you, but mind your own business and cultivate the ground, that your women and your children may have enough to live on.

I now inform you, that it is our intention to live in peace with our father and his people for ever.
