A fierce battle took place at Stones River between December 31, 1862 and January 2, 1863. General Bragg's Confederates withdrew after the battle, allowing General Rosecrans and the Union army to control middle Tennessee. Although the battle was tactically indecisive, it provided a much-needed boost to the North after the defeat at Fredericksburg. Lincoln later wrote to General Rosecrans, "I can never forget [...] you gave us a hard-earned victory, which had there been a defeat instead, the nation could scarcely have lived over."
