BUELL, DON CARLOS (1818-1898), American soldier, was born near Marietta (Ohio), on March 23, 1818. He gradu ated at West Point in 1841, and was company officer of Infantry in the Seminole War of 1841-42 and the Mexican War, winning the brevet of captain at Monterey, and that of major at Con treras-Churubusco. From 1848 to 1861 he acted chiefly as assist ant-adjutant-general. On the outbreak of the Civil War he was appointed lieutenant-colonel, then brigadier-general of volunteers, and major-general of volunteers in March, 1862. He aided in organizing the Army of the Potomac, and was sent, in Nov. 1861, to Kentucky to succeed Gen. William T. Sherman in command. Here he organized and trained the Army of the Ohio, which to the end of its career retained a standard only surpassed by that of the Army of the Potomac. In the spring of 1862 Buell fol lowed the retiring Confederates under Sidney Johnston, served under Halleck in the advance on Corinth, and in the autumn commanded in the campaign in Kentucky against Bragg. A period of manoeuvring virtually ended in the indecisive battle of Perryville. The alleged tardiness of his pursuit, and his ob jection to a plan of campaign ordered by the Washington authori ties, brought about his removal from command. The complaints made against him were investigated in 1862-63, but the result was not published. Subsequently he was offered military em ployment, which he declined. He resigned his volunteer com mission in May, and his regular commission in June 1864. He died near Rockport (Ky.), on Nov. i9, 1898.
