Don Carlos Buell, an American general, born near Marietta, Ohio, March 23, 1818. He graduated at West Point in 1841, and served in the Florida war and on frontier duty till 1845. In the Mexican war he was present at the battles of Palo Alto, Resaca de la Palma, Monterey, Cerro Gordo, Contreras, and Churubusco, where he was severely wounded, receiving the brevets of captain and major. In the latter part of 1847 and in 1848 he was employed in the adjutant general's office at Washington; from 1849 to 1861 as assistant adjutant general in the departments of New Mexico, Texas, the East, the West, and the Pacific. After the commencement of the civil war in 1861 he assisted in organizing the army collected near Washington. In November of that year he was placed in command of the department of the Ohio, his headquarters being at Louisville, Ky. On March 21,1862, he was made major general of volunteers, his department being incorporated with that of the Mississippi, under Gen. Halleck. He appeared with a part of one of his divisions on the battle field of Shiloh, April 6, in time to succor the hard-pressed force under Gen. Grant; on the following day, his other divisions having come up, the confederates were worsted, and fell back to their intrenchments at Corinth. In June he was placed in command of the newly formed district of the Ohio, with his headquarters at Huntsville, Ala. In July and August the confederates, under Bragg, marched into Kentucky, compelling the abandonment of Lexington and Frankfort, and threatening Louisville and even Cincinnati. On Sept. 30 Buell, by order from Washington, turned over his command to Gen. Thomas, upon whose request it was at once restored to Buell. A part of Buell's army came up with a part of the confederate force at Perryville, Oct. 8, where an indecisive action was fought.

The confederates retreated leisurely to Cumberland gap, and Buell did not follow them. On the 24th he was directed to transfer his command to Gen. Rosecrans, and a court of inquiry was ordered to investigate his operations in Tennessee and Kentucky. The action of this court has never been published. Gen. Buell was mustered out of the volunteer service May 23, 1864, resigned his commission in the army June 1, and in 1865 became president of the Green River iron works, in Kentucky.
