remembered as "Sugar Camp," three and one-half miles from Vincennes. Clark was now at the lower end of the "Lower Prairie," and there were two courses to Vincennes which lay on the rising ground across the three miles of flooded prairie.[38] One, by way of the Grand Marais or swamp in the middle of the prairie, was impassable; the other route, known as the "two buttes route," was the difficult alternative. The first butte was "Warrior's Island," a ten-acre hill heavily wooded, a mile and a half from Sugar Camp and two miles from Vincennes. It could be and was reached by the strong men wading breast high, drawing or paddling their feebler comrades in the canoes. The second butte, "Bunker Hill," was not on the direct line to Vincennes, but was a high point to the east on the same plateau on which Vincennes stood. At one o'clock of the twenty-third, the floundering army, half numb with cold and weak from exposure, reached Warrior's Island. From here Clark sent his first message, diplomatically directed to the inhabitants of Vincennes: "GENTLEMEN--Being now within two miles of your village with my army, determined to take your fort this night, and not being willing to surprise you, I take this method to request such of you as are true citizens, and willing to enjoy the liberty I bring you, to remain still in your houses, and those, if any there be, who are friends to the king, will instantly repair to the fort[39] and join the _Hair-buyer General_,[40] and fight like men. And if any such as do not go to the fort shall be discovered afterwards, they may depend on severe punishment. On the contrary, those who are true friends to liberty may depend on being well treated; and I once more request them to keep out of the streets, for every one I find in arms on my arrival I shall treat as an enemy."[41] At eight o'clock that night the famished army waded to Bunker Hill, and soon the outskirts of the town were invested, under fire of the fort. On the twenty-fourth Hamilton surrendered, and the campaign, prosecuted under difficulties which today cannot be justly described, ended in complete triumph. [Illustration: THE ST.
