Battle of Fort Donelson
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. The intention was to open an escape route for retreat to Nashville, Tennessee. Grant was away from the battlefield at the start of the attack, but arrived to rally his men and counterattack. Pillow's attack succeeded in opening the route, but Floyd lost his nerve and ordered his men back to the fort. The following morning, Floyd and Pillow escaped with a small detachment of troops, relinquishing command to Brig. Gen. Simon Bolivar Buckner, who accepted Grant's demand of unconditional surrender later that evening. The battle resulted in virtually all of Kentucky as well as much of Tennessee, including Nashville, falling under Union control.
The battle of Fort Donelson, which began on February 12, took place shortly after the surrender of Fort Henry, Tennessee, on February 6, 1862. Fort Henry had been a key position in the center of a line defending Tennessee, and the capture of the fort now opened the Tennessee River to Union troop and supply movements. About 2,500 of Fort Henry's Confederate defenders escaped before its surrender by marching the 12 miles (19 km) east to Fort Donelson. In the days following the surrender at Fort Henry, Union troops cut the railroad lines south of the fort, restricting the Confederates' lateral mobility to move reinforcements into the area to defend against the larger Union forces.
With the surrender of Fort Henry, the Confederates faced some difficult choices. Grant's army now divided Confederate Gen. Albert Sidney Johnston's two main forces: Major General Leonidas Polk at Columbus, Kentucky, with 12,000 men, and William J. Hardee at Bowling Green, Kentucky, with 14,000 men. Fort Donelson had only about 5,000 men but Floyd and Buckner were moving their 8,000 troops from Russellville, Kentucky, to Clarksville, Tennessee. Union forces might attack Columbus; they might attack Fort Donelson and thereby threaten Nashville, Tennessee; or Grant and Maj. Gen. Don Carlos Buell, who was quartered in Louisville with 45,000 men, might attack Johnston head-on, with Grant following behind Buell. Johnston discussed the situation with his second-in-command, General Pierre G.T. Beauregard, and Hardee at Beauregard's headquarters at Covington House in Bowling Green on February 7. The generals were apprehensive about the ease with which Union gunboats defeated Fort Henry (not comprehending that the rising waters of the Tennessee River played a crucial role by inundating the fort). They decided that Fort Donelson was untenable, and adopted a course of action that forfeited the initiative across most of the Confederate defensive line, tacitly admitting that their defensive strategy for Tennessee was a sham.
The Confederate garrison at Columbus would be evacuated southwards, the Central Kentucky Army withdrawn from Bowling Green to Nashville, and Floyd's troops responsible for the defense of the Cumberland River. Johnston wanted to give command of the district to Beauregard, who had performed ably at Bull Run, but the latter declined because of a throat ailment. Instead, the responsibility went to Floyd, who had just arrived following an unsuccessful assignment under Robert E. Lee in western Virginia. Floyd was a wanted man in the North for alleged graft and secessionist activities when he was Secretary of War in the James Buchanan administration. Floyd's background was political, not military, but he was nevertheless the senior brigadier general on the Cumberland River.
On the Union side, Maj. Gen. Henry W. Halleck, Grant's superior as commander of the Department of the Missouri, was also apprehensive. Halleck had authorized Grant to capture Fort Henry, but now he felt that continuing to Fort Donelson was risky. Despite Grant's success to date, Halleck had little confidence in him, considering Grant to be reckless. Halleck attempted to convince his own rival, Don Carlos Buell, to take command of the campaign to get his additional forces engaged. Despite Johnston's high regard for Buell, the Union general was as passive as Grant was aggressive. Grant never suspected his superiors were considering relieving him, but he was well aware that any delay or reversal might be an opportunity for Halleck to lose his nerve and cancel the operation.
On February 6, Grant wired Halleck: "Fort Henry is ours. ... I shall take and destroy Fort Donelson on the 8th and return to Fort Henry." This self-imposed deadline was overly optimistic due to three factors: miserable road conditions on the twelve-mile march to Donelson, the need for troops to carry supplies away from the rising flood waters (by February 8, Fort Henry was completely submerged), and the damage that had been sustained by Foote's Western Gunboat Flotilla in the artillery duel at Fort Henry. If Grant had been able to move quickly, he might have taken Fort Donelson on February 8. Early in the morning of February 11, Grant held a council of war in which all of his generals supported his plans for an attack on Fort Donelson, with the exception of Brig. Gen. John A. McClernand, who had some reservations. This council in early 1862 was the last one that Grant held for the remainder of the Civil War.
