During the siege of Chattanooga in October and November 1863, a Union observation post on Cameron Hill, which looms high over the city, kept watch on the Confederates surrounding Chattanooga. At 1 P.M. on October 2, for example, Capt. A.S. Cole reported from Cameron Hill, "I see an omnibus filled with people driving along top of Missionary Ridge, stopping often, apparently to make observations."
