George B. Crittenden

George Bibb Crittenden (March 20, 1812 – November 27, 1880) was a career United States Army officer who served in the Black Hawk War, the Army of the Republic of Texas, and the Mexican–American War, and later resigned his commission to serve as a general in the Confederate States Army in the American Civil War.[1]
Just before the start of the Civil War, Crittenden accepted a commission as colonel, in the Confederate States Army infantry on March 16, 1861, although he would not resign his U.S. Army commission until June 10. He was promoted to brigadier general on August 15, 1861 and served briefly as a brigade commander in the Confederate Army of the Potomac in Virginia. He was promoted to major general on November 9, 1861 and commanded the District of East Tennessee. On January 19, 1862, he and Confederate Brig. Gen. Felix Zollicoffer were defeated by Union Brigadier General George H. Thomas at the Battle of Mill Springs,[2] the first important Confederate defeat in the war, breaking the Southern hold on eastern Kentucky.
He briefly commanded the 2nd Division of the Army of Central Kentucky in 1862 but was relieved on March 31. He was arrested the next day on charges of drunkenness by the order of Maj. Gen. William J. Hardee and restored on April 18. General Braxton Bragg ordered a court of inquiry in July and Crittenden resigned as a general officer, reverting to colonel in October 1862.
