The Defense of Cincinnati occurred during what is now referred to as the Confederate Heartland Offensive or Kentucky Campaign of the American Civil War, from September 1 through September 13, 1862. Confederate Brigadier General Henry Heth was sent north from Lexington, Kentucky, to threaten Cincinnati, Ohio, then the sixth-largest city in the United States. Heth was under orders from his superior, Major General Edmund Kirby Smith, not to attack the city, but to instead make a "demonstration". Once Heth arrived and reconnoitered the defenses, he realized an attack was pointless. After a few minor skirmishes, he took his men back to Lexington.
