The most sensitive, and in many ways the most crucial areas, along the Mississippi River and in western Tennessee along the Tennessee and the Cumberland rivers were placed under the command of Maj. Gen. Leonidas Polk and Brig. Gen. Gideon J. Pillow. The latter had initially been in command in Tennessee as that State's top general. Their impolitic occupation of Columbus, Kentucky, on September 3, 1861, two days before Johnston arrived in the Confederacy's capital of Richmond, Virginia, after his cross-country journey, drove Kentucky from its stated neutrality. The majority of Kentuckians allied with the Union camp. Polk and Pillow's action gave Union Brig. Gen. Ulysses S. Grant an excuse to take control of the strategically located town of Paducah, Kentucky, without raising the ire of most Kentuckians and the pro-Union majority in the State legislature.
