Except for Ft. Henry, Donelson, Shiloh, Corinth, Memphis, Island Number 10, Columbus Ky, Pea Ridge, Nashville, Iuka, and even New Orleans .... and elsewhere, I am sure I am missing some. Even with a Union loss at Perryville, the CSA had to retreat, and 1862 left the Union in pretty firm control of Kentucky, Missouri, Arkansas, and everywhere on the Mississippi except Vickburg.
