Nothing, however, revealed their savage nature so well as their rapid decline under the influence of whiskey. As we shall see hereafter, one of the great motives that impelled their attacks on the flat boats of the Ohio river, was their desire not only for plunder, but for rum. The boats generally contained a liberal supply. Nothing was more common than drunkenness after the greedy and avaricious traders of the Wabash got into their midst and bartered them brandy for their most valuable peltries. Potawatomi were found camping about Vincennes in great numbers and trading everything of value for liquor. In General Harrison's day, he endeavored time and time again to stop this nefarious traffic. On all occasions when treaties were to be made, or council fires kindled, he issued proclamations prohibiting the sale of liquor to the Indians. These proclamations were inserted in the Western Sun, at Vincennes, on more than one occasion, but they were unavailing. The temptation of a huge profit was too strong. Carousals and orgies took place when the Indians were under the influence of "fire-water." Fights and murders were frequent. At the last, whiskey destroyed the last vestige of virtue in their women, and valor in their warriors. After the crushing of the Prophet in 1811, and the destruction of British influence in the northwest, consequent upon the war of 1812, the decline of the Potawatomi was swift and appalling. The terrible ravages of "fire-water" played no inconsiderable part. Many of their principal chieftains became notorious drunkards reeling along the streets of frontier posts and towns and boasting of their former prowess. Even the renowned Topenebee, the last principal chief of the tribe of the river St. Joseph was no exception. Reproached by General Lewis Cass, because he did not remain sober and care for his people, he answered: "Father, we do not care for the land, nor the money, nor the goods; what we want is whiskey! Give us whiskey!" The example set by the chiefs was not neglected by their followers.
