The Battle of Fort Donelson was fought from February 11–16, 1862, in the Western Theater of the American Civil War. The Union capture of the Confederate fort near the Tennessee–Kentucky border opened the Cumberland River, an important avenue for the invasion of the South. The Union's success also elevated Brig. Gen. Ulysses S. Grant from an obscure and largely unproven leader to the rank of major general, and earned him the nickname of "Unconditional Surrender" Grant. Following his capture of Fort Henry on February 6, Grant moved his army (later to become the Union's Army of the Tennessee) 12 miles (19 km) overland to Fort Donelson, from February 11 to 13, and conducted several small probing attacks. On February 14, Union gunboats under Flag Officer Andrew H. Foote attempted to reduce the fort with gunfire, but were forced to withdraw after sustaining heavy damage from the fort's water batteries. On February 15, with the fort surrounded, the Confederates, commanded by Brig. Gen. John B. Floyd, launched a surprise attack, led by his second-in-command, Brig. Gen. Gideon Johnson Pillow, against the right flank of Grant's army.
