On November 1, seven weeks after Colfax's visit, Frémont ordered Grant to make demonstrations along the Mississippi against the Confederates, but not to directly engage the enemy. The following day Frémont was relieved from command by Lincoln for refusing to revoke his August 30 edict. On November 7, Grant attacked Belmont drawing Confederate troops from Columbus and inflicting Confederate casualties. In February 1862, Grant, in combination with the Union navy, captured Confederate Forts Henry and Donelson, forcing Polk to abandon Columbus. The Confederate army was finally pushed out of Kentucky after Union General Don Carlos Buell defeated Confederate General Braxton Bragg at the Battle of Perryville in October, 1862.
