When the British sent a strong army to catch him, he could not be found. But soon he would be fighting the British in some new place. He was always playing hide and seek. The British called him the Swamp Fox. That was because he was so hard to catch. They could not conquer the country until they could catch Marion. And they never could catch the Swamp Fox. At one time Marion came out of the woods to take a little British fort. This fort was on the top of a high mound. It was one of the mounds built a long time ago by the Indians. Marion put his men all round the fort, so that the men in the fort could not get out to get water. He thought that they would have to give up. But the men in the fort dug a well inside the fort. Then Marion had to think of another plan. Marion’s men went to the woods and cut down stout poles. They got a great many poles. When night came, they laid a row of poles along-side one another on the ground. Then they laid another row across these. Then they laid another row on top of the last ones, and across the other way again. [Illustration: Marion’s Tower.] They laid a great many rows of poles one on top of another. They crossed them this way and that. As the night went on, the pile grew higher. Still they handed poles to top of the pile. Before morning came, they had built a kind of tower. It was higher than the Indian mound. As soon as it was light, the men on Marion’s tower began to shoot. The British looked out. They saw a great tower with men on it. The men could shoot down into the fort. The British could not stand it. They had to give up. They were taken prisoners. CLARK AND HIS MEN. At the time of the Revolution there were but few people living on the north side of the O-hi-o River. But there were many Indians there. These Indians killed a great many white people in Ken-tuck-y. The Indians were sent by British officers to do this killing. There was a British fort at Vincennes in what is now In-di-an-a. There was another British fort or post at Kas-kas-ki-a in what is now the State of Il-li-nois. George Rogers Clark was an American colonel. He wanted to stop the murder of the settlers by the Indians. He thought that he could do it by taking the British posts. He had three hundred men. They went down the O-hi-o River in boats. They landed near the mouth of the O-hi-o River. Then they marched a hundred and thirty miles to Kas-kas-ki-a. Kas-kas-ki-a was far away from the Americans. The people there did not think that the Americans would come so far to attack them. When Clark got there, they were all asleep. He marched in and took the town before they waked up. The people living in Kaskaskia were French. By treating them well, Clark made them all friendly to the Americans.
