William Clark, who was at that same time a figurehead in the implementation of the Indian Removal Act, associated with the Trail of Tears further south. The treaty was signed two months after the end of the Black Hawk War in northwestern Illinois, between the Sauk tribe and the United States. The Sauk disputed the validity of a treaty similar to the Kaskaskia treaty of 1803, arranged by William Henry Harrison in 1804. The Sauk lost the Black Hawk War, resulting in the death of half of the Sauk forces. The Kaskaskia treaty of 1832 relinquished all lands reserved for the tribe in the 1803 treaty with the exception of 350 acres near the town of Kaskaskia, Illinois, reserved to Ellen Ducoigne, a daughter of Jean Baptiste Ducoigne who had married a white man. All other members of all five tribes mentioned in the treaty were relocated to Indian Country in modern-day Kansas. Effects on the Mississippi River From St. Louis to the confluence of the Ohio River, the Mississippi became wider and more shallow, resulting in more severe seasonal flooding. In the late 19th century, the town was cut off from the Illinois mainland and mostly destroyed by repeated flooding and a channel change by the Mississippi River. Much of the former property of Kaskaskia and other French colonial towns on the river has been lost. Following the Great Flood of 1844, residents of Kaskaskia relocated the town to the south. The original location of Kaskaskia became an island, surrounded by the Mississippi River. The flood of 1881 destroyed all remnants of the original town and the Mississippi shifted into the channel of the Kaskaskia River, passing east instead of west of the town. Parts of the town were rebuilt in the new area. As the Mississippi continued to flow through its new bed, earth was deposited so that the village land became physically attached to the west bank of the river, which primarily lies within the boundaries of the state of Missouri. Now a bayou, the old channel is regularly flooded by the river. A small bridge carries traffic from the mainland over the bayou to Kaskaskia and its surrounding farmlands in the floodplain. A levee lines the river to the east. In 1893 the people of the town moved and rebuilt the Church of the Immaculate Conception at Kaskaskia. They also built a shrine in a similar
