In 1778, after encountering endless difficulties and delays, he finally raised a hundred and fifty backwoods riflemen. In May they started down the Ohio in flatboats to undertake the allotted task. They drifted and rowed down-stream to the Falls of the Ohio, where Clark founded a log-hamlet, which has since become the great city of Louisville. Here he halted for some days and was joined by fifty or sixty volunteers; but a number of the men deserted, and when, after an eclipse of the sun, Clark again pushed off to go down with the current, his force was but about one hundred and sixty riflemen. All, however, were men on whom he could depend--men well used to frontier warfare. They were tall, stalwart backwoodsmen, clad in the hunting-shirt and leggings that formed the national dress of their kind, and armed with the distinctive weapon of the backwoods, the long-barreled, small-bore rifle. Before reaching the Mississippi the little flotilla landed, and Clark led his men northward against the Illinois towns. In one of them, Kaskaskia, dwelt the British commander of the entire district up to Detroit. The small garrison and the Creole militia taken together outnumbered Clark's force, and they were in close alliance with the Indians roundabout. Clark was anxious to take the town by surprise and avoid bloodshed, as he believed he could win over the Creoles to the American side. Marching cautiously by night and generally hiding by day, he came to the outskirts of the little village on the evening of July 4th, and lay in the woods near by until after nightfall. 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.
