Billy Caldwell, baptized Thomas Caldwell (March 17, 1782 – September 28, 1841), known also as Sauganash ([one who speaks] English), was a British-Potawatomi fur trader who was commissioned captain in the Indian Department of Canada during the War of 1812. He moved to the United States in 1818 and settled there. In 1829 and 1833 he negotiated treaties on behalf of the United Nations of Chippewa, Ottawa and Potawatomi with the United States, and became a leader of a Potawatomi band at Trader's Point (Iowa Territory). He worked to gain the boundary long promised by the British between white settlers and Indians, but never achieved it. Born in a Mohawk refugee camp near Fort Niagara, Billy was the son of a Mohawk mother (Caldwell Oral Family History - Ontario) and William Caldwell, a Scots-Irish immigrant to North America and a Loyalist British officer during the American Revolutionary War. He became multilingual, learning Potawatomi, English, and French. After moving to the United States in 1818, Caldwell became a fur trader and learned the Potawatomi language, an Algonquian language; he negotiated with numerous tribes in the Lake Michigan area. He gained their respect and also acted as a translator and negotiator between the government and American Indians. In 1829, Caldwell represented the Chippewa, Ottawa and Potawatomi peoples of the United Nations Tribes in negotiating the Second Treaty of Prairie du Chien with the United States. For his work, the US granted him a 1600-acre tract, known as the Caldwell Reserve, along the Chicago River. Eighty acres is included within the Cook County Forest Preserve. Together with Alexander Robinson, Caldwell also negotiated the 1833 Treaty of Chicago for the United Nations Tribes. The US had appointed the two mixed-race men as chiefs in 1829 to fill vacant positions, to encourage the United Nations Tribes to sign the cessions. The treaty led to the final removal of American Indians from that region, to west of the Mississippi River. In 1835, Caldwell migrated with his people from the Chicago region west to Platte County, Missouri. As a result of the Platte Purchase in 1836, Caldwell and his band were removed from Missouri to Iowa Territory, to the area of Trader's Point (Pointe aux Poules) on the east bank of the Missouri River. While living at Trader's Point, Caldwell led a band of approximately 2000 Potawatomi. Their settlement became known as Camp Caldwell. In 1841 Caldwell
