Union Gen. Don Carlos Buell finally gave up his half-hearted pursuit of Bragg at London, Kentucky. Taken in balance with his performance at Perryville, this soon would cost him his command.
Having now passed into his own department in East Tennessee, Gen. Edmund Kirby Smith resumed command of his army, glad to be out from under Bragg's command, which he had grown to hold in low regard. Smith will go on to distinguish himself during the rest of the war. He will become one of the last Confederate generals to surrender his army, which he will finally do in June 1865, almost 2 months after Lee's surrender at Appomattox, and more than 2 weeks after the Army of Tennessee surrendered in North Carolina. And Gen. Edmund Kirby Smith will have the distinction of being the last surviving full Confederate general until his death in 1893.
