This year’s annual “A Walk in the Past” cemetery tour by Heritage Alliance will have a little more drama and delve into a troublesome time in Warren County history – the Civil War era.“With this being the 150th anniversary of the Civil War and the Battle of Rebel Hill fought here in McMinnville, I thought we should focus on Civil War-era personalities,” said Heritage Alliance president Jimmy Haley. Due to our resources and the railroad line, both Union and Confederate armies established headquarters in Warren County. McMinnville changed hands at least five times during the war.
