Red Bird was a leader of the Winnebago Native American tribe. He was a leader in the Winnebago War of 1827 against Americans in the United States making intrusions into tribal lands for mining. He was for many years one of the most friendly and trusted of the Wisconsin Native Americans. In the late 1820s Red Bird and his followers began to grow uneasy over the encroachments of lead miners on Ho-Chunk land. The tribe had an uneasy relationship with the dominant culture's legal concepts and often continued to follow tribal practices of justice. This tension resulted in several incidents, including confrontations with Secretary of War, John C. Calhoun. One incident involved the mistaken information channeled to the tribe that two Ho-Chunk executions were conducted at Fort Snelling in 1826 for a murder they did not commit. As white miners continued to extract resources near Winnebago villages on the Rock River, the War Department sought to keep tribes from mining the same minerals, in fear that the land would become contentious. Near Prairie du Chien on June 28, 1827, Red Bird had become increasingly angered by treatment of the tribe. Encroachment on native lands, unfair incarceration, and increasing violence led to escalating tensions. Under pressure from the tribe to defend their interests, Red Bird set off with two others, Chickhonsic and Wekau ; eventually meeting a trader, John Lockwood and a former British soldier, Duncan Graham, who advised against violence. Upon arriving at the cabin of Registre Gagnier, the party was met with a friendly welcome and invited in for refreshment. Gagnier, feeling suspicious about the nature of the visit, reached for his rifle, thus setting off the following events. Chickhonsic shot Solomon Lipcap. Wekau attempted to shoot Mrs. Gagnier, but she and her son escaped and gave the alarm in Prairie du Chien.

The Ho-Chunk, also known as Hocąk, Hoocągra, or Winnebago, are a Siouan-speaking Native American people whose historic territory includes parts of Wisconsin, Minnesota, Iowa, and Illinois. Today, Ho-Chunk people are enrolled in two federally recognized tribes, the Ho-Chunk Nation of Wisconsin and the Winnebago Tribe of Nebraska.
