American Civil War: The Andrews Raid (the Great Locomotive Chase) occurs, starting from Big Shanty, Georgia (now Kennesaw).

The Great Locomotive Chase was a military raid that occurred April 12, 1862, in northern Georgia during the American Civil War. Volunteers from the Union Army, led by civilian scout James J. Andrews, commandeered a train, The General, and took it northward toward Chattanooga, Tennessee, doing as much damage as possible to the vital Western and Atlantic Railroad (W&A) line from Atlanta to Chattanooga as they went. They were pursued by Confederate forces at first on foot, and later on a succession of locomotives, including The Texas, for 87 miles (140 km).

Kennesaw is a suburban city northwest of Atlanta in Cobb County, Georgia, United States, located within the greater Atlanta metropolitan area. Known from its original settlement in the 1830s until 1887 as Big Shanty, it became Kennesaw under its 1887 charter. According to the 2020 census, Kennesaw had a population of 33,036, a 10.9% increase in population over the preceding decade. Kennesaw has an important place in railroad history. During the Civil War, Kennesaw was the staging ground for the Great Locomotive Chase on April 12, 1862. Kennesaw is home to Kennesaw State University, an R2 research institution and the third-largest public university in the state of Georgia.
