8. In the latter part of June Rosecrans succeeded in crowding General Bragg out of Tennessee. The Union general followed and took post at Chattanooga, on the left bank of the Tennessee. During the summer Bragg was reinforced by the corps of Johnston and Longstreet.
9. On the 19th of September he turned upon the Federals at Chickamauga Creek, in the northwest angle of Georgia. A hard battle was fought, but night came with the victory undecided. On the following morning the fight was renewed. Bragg cut through the Union battle line and drove the right wing into a rout. General Thomas, with desperate firmness, held the left until nightfall, and then withdrew into Chattanooga. The Union loss amounted to nearly nineteen thousand, and that of the Confederates was even greater.
