The Battle of Ringgold Gap occurred on November 27, 1863, near Ringgold, Georgia, between the Confederate and Union armies. This engagement was a part of the Chattanooga Campaign and followed closely after the Confederate defeat at the Battle of Missionary Ridge. The Confederate forces, led by Major General Patrick R. Cleburne, were tasked with defending Ringgold Gap, a crucial mountain pass, to ensure the safe retreat of the Confederate artillery and wagon trains following their loss. Despite being heavily outnumbered and initially doubtful of their defensive capabilities, Cleburne's troops successfully held the pass against the Union army led by General Joseph Hooker.

As the Confederates fortified positions within the Ringgold Gap and surrounding areas, the Union forces advanced. The fog of war, combined with the challenging terrain, made the battle particularly chaotic. Union divisions, under commanders like General Peter Osterhaus and General John Geary, made several assaults into the gap and surrounding areas but were consistently repelled by the Confederate defenses. Throughout the battle, the Confederate forces utilized strategic placements, including hidden artillery, to fend off the Union advancements. Even with their numerical advantage, the Union army faced heavy resistance and found it difficult to gain any substantial ground.

After several hours of intense fighting, Cleburne received word that the remaining Confederate army had safely passed through the gap. With this, he began a strategic retreat, leaving behind skirmishers to cover their withdrawal. The battle concluded with the Confederates achieving their objective of safeguarding the retreat of their main force. They reported 221 casualties while the Union forces suffered 509 casualties. Despite criticisms of General Hooker's handling of the battle, he retained his position in the Union army. The Battle of Ringgold Gap showcased the tactical prowess of the Confederate forces, even when faced with overwhelming odds.
