John C. Bates

John Coalter Bates (August 26, 1842 – February 4, 1919) was a United States Army officer who served as Chief of Staff of the United States Army from January to April 1906. Along with Arthur MacArthur Jr., Bates was one of the last American Civil War veterans still on active duty in the United States military at the time of his retirement.

Early life and education
Bates was born in St. Charles County, Missouri to congressman and future Attorney General Edward Bates and Julia Davenport Coalter. He was educated at Washington University in St. Louis. He was commissioned a first lieutenant with the 11th Infantry Regiment in May 1861. He later became an aide to General George G. Meade, reaching the brevet rank of lieutenant colonel for gallant and meritorious service in operations, resulting in the capture of Richmond and surrender of General Robert E. Lee's army in April 1865.

Military career
Bates later served on the Indian Frontier for many years (being promoted to major in 1882 and to lieutenant colonel in 1886), was made a colonel of the 2nd Infantry Regiment in 1892, and in May 1898 was promoted to brigadier general of an Independent Brigade consisting of the 3rd Infantry Regiment and 20th Infantry Regiment in the Spanish–American War and commanded a division of volunteers in the Philippines in the early stages of the Philippine–American War. He was military governor of Cienfuegos in 1899 and went that year to the Philippines, where he conducted negotiations with the Sultan of Sulu. From 1900 to 1901, he commanded the 1st Division, Eighth Army Corps, conducted operations against insurgents in southern Luzon, and then commanded that department. Bates commanded a provisional division in maneuvers at Fort Riley and commanded the Departments of the Missouri and the Lakes from 1901 to 1904 and later the Northern Division for a year before serving as Chief of Staff of the United States Army from January 15 to April 13, 1906. During this time, he was promoted to Lieutenant general. He retired from active service in April 1906 at his request, shortly before reaching the mandatory retirement age of 64. He was the last Army Chief of Staff to have served in the American Civil War.

Later life and death
Bates was a member of the Military Order of the United States Loyal Legion and the Republic's Grand Army. He died in San Diego, California on February 4, 1919.
