The surprise was complete, and no resistance was attempted. For twenty-four hours the Creoles were in abject terror. Then Clark summoned their chief men together and explained that he came as their ally, and not as their foe, and that if they would join with him they should be citizens of the American republic, and treated in all respects on an equality with their comrades. The Creoles, caring little for the British, and rather fickle of nature, accepted the proposition with joy, and with the most enthusiastic loyalty toward Clark. Not only that, but sending messengers to their kinsmen on the Wabash, they persuaded the people of Vincennes likewise to cast off their allegiance to the British king, and to hoist the American flag.
So far, Clark had conquered with greater ease than he had dared to hope. But when the news reached the British governor, Hamilton, at Detroit, he at once prepared to reconquer the land.
He had much greater forces at his command than Clark had; and in the fall of that year he came down to Vincennes by stream and portage, in a great fleet of canoes bearing five hundred fighting men-British regulars, French partizans, and Indians. The Vincennes Creoles refused to fight against the British, and the American officer who had been sent thither by Clark had no alternative but to surrender.
If Hamilton had then pushed on and struck Clark in Illinois, having more than treble Clark's force, he could hardly have failed to win the victory; but the season was late and the journey so difficult that he did not believe it could be taken.
Accordingly he disbanded the Indians and sent some of his troops back to Detroit, announcing that when spring came he would march against Clark in Illinois.
If Clark in turn had awaited the blow he would have surely met defeat; but he was a greater man than his antagonist, and he did what the other deemed impossible.
Finding that Hamilton had sent home some of his troops and dispersed all his Indians, Clark realized that his chance was to strike before Hamilton's soldiers assembled again in the spring.
Accordingly he gathered together the pick of his men, together with a few Creoles, one hundred and seventy all told, and set out for Vincennes. At first the journey was easy enough, for they passed across the snowy Illinois prairies, broken by great reaches of lofty woods. They killed elk, buffalo, and deer for food, there being no difficulty in getting all they wanted to eat; and at night they built huge fires by which to sleep, and feasted "like Indian war-dancers," as Clark said in his report.
But when, in the middle of February, they reached the drowned lands of the Wabash, where the ice had just broken up and everything was flooded, the difficulties seemed almost insuperable, and the march became painful and laborious to a degree. All day long the troops waded in the icy water, and at night they could with difficulty find some little hillock on which to sleep. Only Clark's indomitable courage and cheerfulness kept the party in heart and enabled them to persevere. However, persevere they did, and at last, on February 23, they came in sight of the town of Vincennes. They captured a Creole who was out shooting ducks, and from him learned that their approach was utterly unsuspected, and that there were many Indians in town.
Clark was now in some doubt as to how to make his fight. The British regulars dwelt in a small fort at one end of the town, where they had two light guns; but Clark feared lest, if he made a sudden night attack, the townspeople and Indians would from sheer fright turn against him. He accordingly arranged, just before he himself marched in, to send in the captured duck-hunter, conveying a warning to the Indians and the Creoles that he was about to attack the town, but that his only quarrel was with the British, and that if the other inhabitants would stay in their own homes they would not be molested. Sending the duck-hunter ahead, Clark took up his march and entered the town just after nightfall. The news conveyed by the released hunter astounded the townspeople, and they talked it over eagerly, and were in doubt what to do. The Indians, not knowing how great might be the force that would assail the town, at once took refuge in the neighboring woods, while the Creoles retired to their own houses. The British knew nothing of what had happened until the Americans had actually entered the streets of the little village. Rushing forward, Clark's men soon penned the regulars within their fort, where they kept them surrounded all night. The next day a party of Indian warriors, who in the British interest had been ravaging the settlements of Kentucky, arrived and entered the town, ignorant that the Americans had captured it. Marching boldly forward to the fort, they suddenly found it beleaguered, and before they could flee they were seized by the backwoodsmen. In their belts they carried the scalps of the slain settlers. The savages were taken redhanded, and the American frontiersmen were in no mood to show mercy. All the Indians were tomahawked in sight of the fort.
For some time the British defended themselves well; but at length their guns were disabled, all of the gunners being picked off by the backwoods marksmen, and finally the garrison dared not so much as appear at a port-hole, so deadly was the fire from the long rifles. Under such circumstances Hamilton was forced to surrender.
No attempt was afterward made to molest the Americans in the land they had won, and upon the conclusion of peace the Northwest, which had been conquered by Clark, became part of the United States.
