Fortune favored him. That evening the officers of the garrison had given a great ball to the mirth-loving Creoles, and almost the entire population of the village had gathered in the fort, where the dance was held. While the revelry was at its height, Clark and his tall backwoodsmen, treading silently through the darkness, came into the town, surprised the sentries, and surrounded the fort without causing any alarm.
All the British and French capable of bearing arms were gathered in the fort to take part in or look on at the merry-making. When his men were posted Clark walked boldly forward through the open door, and, leaning against the wall, looked at the dancers as they whirled around in the light of the flaring torches. For some moments no one noticed him. Then an Indian who had been lying with his chin on his hand, looking carefully over the gaunt figure of the stranger, sprang to his feet, and uttered the wild war-whoop. Immediately the dancing ceased and the men ran to and fro in confusion; but Clark, stepping forward, bade them be at their ease, but to remember that henceforth they danced under the flag of the United States, and not under that of Great Britain.
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.
