Six Armies in Tennessee

When Vicksburg fell to Union forces under General Grant in July 1863, the balance turned against the Confederacy in the trans-Appalachian theater. The Federal success along the river opened the way for advances into central and eastern Tennessee, which culminated in the bloody battle of Chickamauga and then a struggle for Chattanooga. Chickamauga is usually counted as a Confederate victory, albeit a costly one. That battle-indeed the entire campaign-is marked by muddle and blunders occasionally relieved by strokes of brilliant generalship and high courage. The campaign ended significant Confederate presence in Tennessee and left the Union poised to advance upon Atlanta and the Confederacy on the brink of defeat in the western theater.
