During his second term, Grant's Indian policy fell apart. On April 11, 1873, Major General Edward Canby was killed in Northern California south of Tule Lake by Modoc leader Kintpuash, in a failed peace conference to end the Modoc War. Grant ordered restraint after Canby's death. The army captured Kintpuash, who was convicted of Canby's murder and hanged on October 3 at Fort Klamath, while the remaining Modoc tribe was relocated to the Indian Territory. In 1874, the army defeated the Comanche at the Battle of Palo Duro Canyon, forcing them to finally settle at the Fort Sill reservation in 1875. Grant pocket-vetoed a bill in 1874 protecting bison and supporting Interior Secretary Columbus Delano, who believed correctly the killing of bison would force Plains Native Americans to abandon their nomadic lifestyle.
