In Tennessee, General Grant forces Fort Donelson's "unconditional and immediate" surrender

After the failure to break out the day before, Confederate commanders determined their position hopeless and asked for surrender terms. Famously, Union commander U.S. Grant refused all terms and thousands of Confederates became prisoners in what was celebrated across the North as a turning point in the war.  Some Confederates escaped; Brigadier General John Buchanan Floyd, under indictment by Congress for treason, fled by boat and the cavalry commander Nathan Bedford Forest led his men to safety in the early morning darkness.
