The Old Johnson County Courthouse was completed in 1842 and functioned as the County seat until 1871. The Courthouse was the site of a murder of the newly elected county clerk, Marsh Foster, by the former clerk's son William McCown on February 18, 1861. This was just before the official start of the war, but was based on the political sympathies of the two men. The men of Johnson County quickly formed troops both Union and Confederate. Local lore says that the two armies, the beginning of Cockrell's Brigade (Confederate) and Emory Foster's (Union) took turns drilling on the same parade ground. By the end of the war the town square had become a Union army camp. A hotel serving as a hospital and other buildings constructed for stables and barracks.
