In April 1862, a number of Union soldiers stole The General and a number of box cars from Big Shanty(Kennesaw) north of Atlanta and headed north towards Chattanooga causing as much damage as the could to the Atlanta and Western Railroad on their way north. They were chased by the guard of the train, on foot, hand cart and other locomotives, until they ran out of fuel and were captured. A number were subsequently hanged as spies. The General is now preserved at the place it was stolen, and is on display in the Kennesaw Museum.
Co-ed note - Just a little more info from The General's own website :
The General is a type 4-4-0 steam locomotive that was the subject of the Great Locomotive Chase of the American Civil War. The locomotive is preserved at the Southern Museum of Civil War and Locomotive History in Kennesaw, Georgia, and it is listed on the National Register of Historic Places. Built in 1855 by Rogers, Ketchum and Grosvenor.
