the area often called the Western Department or Western Military Department. Johnston's appointment as a full general by his friend and admirer Jefferson Davis already had been confirmed by the Confederate Senate on August 31, 1861. The appointment had been backdated to rank from May 30, 1861, making him the second highest ranking general in the Confederate States Army. Only Adjutant General and Inspector General Samuel Cooper ranked ahead of him. After his appointment, Johnston immediately headed for his new territory. He was permitted to call on governors of Arkansas, Tennessee and Mississippi for new troops, although this authority was largely stifled by politics, especially with respect to Mississippi. On September 13, 1861, Johnston ordered Brig. Gen. Felix Zollicoffer with 4,000 men to occupy Cumberland Gap in Kentucky in order to block Union troops from coming into eastern Tennessee. The Kentucky legislature had voted to side with the Union after the occupation of Columbus by Polk. By September 18, Johnston had Brig. Gen. Simon Bolivar Buckner with another 4,000 men blocking the railroad route to Tennessee at Bowling Green, Kentucky. Johnston had fewer than 40,000 men spread throughout Kentucky, Tennessee, Arkansas and Missouri. Of these, 10,000 were in Missouri under Missouri State Guard Maj. Gen. Sterling Price. Johnston did not quickly gain many recruits when he first requested them from the governors, but his more serious problem was lacking sufficient arms and ammunition for the troops he already had. As the Confederate government concentrated efforts on the units in the East, they gave Johnston small numbers of reinforcements and minimal amounts of arms and material. Johnston maintained his defense by conducting raids and other measures to make it appear he had larger forces than he did, a strategy that worked for several months. Johnston's tactics had so annoyed and confused Union Brig. Gen. William Tecumseh Sherman in Kentucky that he became paranoid and mentally unstable. Sherman overestimated Johnston's forces, and had to be relieved by Brig. Gen. Don Carlos Buell on November 9, 1861. However, in his Memoirs. Sherman strongly refutes this account. Battle of Mill Springs East Tennessee (a heavily pro-Union region of the South during the Civil War) was held for the Confederacy by two unimpressive brigadier generals appointed by Jefferson Davis: Felix Zollicoffer, a brave but untrained and inexperienced officer, and soon-to-be Maj. Gen. George B. Crittenden, a former U.S. Army officer with apparent alcohol problems. While
