Map of the Battlefield of Chattanooga

The Chattanooga Campaign, about a decade after American blood was spilt.

The Chattanooga Campaign was a series of critical battles fought in late 1863 during the American Civil War, centered around the strategically and economically important city of Chattanooga, Tennessee. Union forces, initially besieged and cut off by Confederate troops, launched a series of offensives to break the siege and secure control of the region. Key engagements included the battles of Lookout Mountain and Missionary Ridge, where Union victories opened the door for General Sherman’s march to Atlanta.

This battle plan of the Chattanooga Campaign depicts the terrain and general troop movements that played a pivotal role in shaping the outcome of the conflict in the Western Theater. It was drawn under the authority of Brigadier General William Farr Smith and published in 1875 by the U.S. War Department. The pivotal city is located in the center, surrounded by Union defenses (dark blue) and Rebel attackers (red). Relief is shown in hachure and a variety of strategic features are shown, including railroads, prominent landmarks, and even individual buildings.
