The Confederate Heartland Offensive, also known as the Kentucky Campaign, was an American Civil War campaign conducted by the Confederate States Army in Tennessee and Kentucky where Generals Braxton Bragg and Edmund Kirby Smith tried to draw neutral Kentucky into the Confederacy by outflanking Union troops under Major General Don Carlos Buell. Though they scored some successes, notably a tactical win at Perryville, they soon retreated, leaving Kentucky primarily under Union control for the rest of the war.
