The document discusses the key events and policies during Ulysses S. Grant's presidency, focusing on the Comstock Lode, the construction of the Transcontinental Railroad, and the conflicts with Native American tribes, particularly the Lakota Sioux. It highlights Grant's efforts to maintain peaceful relations with Native Americans, which faced challenges due to the influx of settlers and the ensuing military conflicts exemplified by the Battle of the Little Bighorn. Custer's death in battle further complicated Grant's Indian policy, leading to increased military intervention against Native tribes.
