The TA Ranch is significant as the site of the famous Johnson County War of 1892. The ranch is also important for its contribution to the development of cattle ranching in Johnson County. The TA Ranch was established in 1882 and is one of the first ranches in Johnson County. The TA Ranch is the only remaining Johnson County War battle site which retains its associated buildings and structures. The marks of the battle are still evident in the barn and the ranch house; battle trenches still exist where both the defenders of Buffalo and the ''invaders'' entrenched themselves against the shower of bullets. Following the 1892 battle the ranch expanded. Many buildings were added to support the large amount of manpower and livestock necessary to the pre-mechanization way of life.
