Edward Richard Sprigg Canby graduated from West Point in 1839. He had a distinguished career in the Civil War, preventing Confederate General Sibley from reaching California and leading the troops that took Mobile in 1865. After the war, Canby was named army commander of the Department of the Columbia. He went to California where he participated in the Modoc War. The Modoc band. entrenched in the lava beds south of Tule Lake, resisted army attacks so effectively that a peace conference was arranged in 1873. Captain Jack (Kintpuash), the Modoc leader, interrupted the proceedings and shot Canby, along with the president of the peace commissioners and a Methodist minister. Captain Jack took Canby's uniform and wore it in battle after escaping. The murders caused an outrage across the country, and President Grant demanded retribution for the death of the Civil War hero. Ultimately, Captain Jack was executed, and the Modocs were went east to a remote part of the Indian Territory.
