Chattanooga and its vicinity. Buell disposed his line from Huntsville, Ala., to McMinnsville, Warren co., Tenn. So lay the opposing armies when Kirby Smith left Knoxville to invade Kentucky. Bragg crossed the Tennessee, just above Chattanooga, on Aug. 21, with thirty-six regiments of infantry, five of cavalry, and forty guns. Louisville was his destination. He advanced among the rugged mountains towards Buell's left at McMinnsville as a feint, but fairly flanked the Nationals. This was a cavalry movement, which resulted in a battle there. The horsemen were led by General Forrest, who, for several days, had been hovering around Lebanon, Murfreesboro, and Nashville. Attempting to cut off Buell's communications, he was confronted (Aug. 30) by National cavalry under E. P. Fyffe, of Gen. T. J. Wood's division, who had made a rapid march. After a short struggle the Confederates were routed. Supposing Bragg was aiming at Nashville, Buell took immediate measures to defend that city.
