American Civil War: The Battle of Wauhatchie, one of the few night battles of the war, concluded with the Union Army opening a supply line to troops in Chattanooga, Tennessee.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

The Battle of Wauhatchie was fought October 28–29, 1863, in Hamilton and Marion counties, Tennessee, and Dade County, Georgia, in the American Civil War. A Union force had seized Brown's Ferry on the Tennessee River, opening a supply line to the Union army in Chattanooga. Confederate forces attempted to dislodge the Union force defending the ferry and again close this supply line but were defeated. Wauhatchie was one of the few night battles of the Civil War.

During the American Civil War, the United States Army, the land force that fought to preserve the collective Union of the states, was often referred to as the Union army, the federal army, or the northern army. It proved essential to the restoration and preservation of the United States as a working, viable republic.
