Question: Which Confederate general failed to capture the Union fort at the city where William Henry Sneed live when he died?

full_context: Document 1: William Henry Sneed: William Henry Sneed (August 27, 1812 – September 18, 1869) was an American attorney and politician, active initially in Murfreesboro, Tennessee, and later in Knoxville, Tennessee, during the mid-19th century. He was a member of the United States House of Representatives for Tennessee's 2nd congressional district during the Thirty-fourth Congress (1855–1857). In the months leading up to the Civil War, he became a leader of Knoxville's secessionist movement. Along with his successful career as an attorney, Sneed was involved in a number of business ventures, most notably the Lamar House Hotel, which he purchased in 1856.
Document 2: Battle of Franklin (1864): The Battle of Franklin was fought on November 30, 1864, in Franklin, Tennessee, as part of the Franklin -- Nashville Campaign of the American Civil War. It was one of the worst disasters of the war for the Confederate States Army. Confederate Lt. Gen. John Bell Hood's Army of Tennessee conducted numerous frontal assaults against fortified positions occupied by the Union forces under Maj. Gen. John M. Schofield and was unable to break through or to prevent Schofield from a planned, orderly withdrawal to Nashville.
Document 3: John L. Helm: Helm was first elected to the Kentucky House of Representatives in 1826; between 1826 and 1843 he served eleven one-year terms in the state house. In 1844 he was elected to the state senate, where he served continuously until he was chosen as the Whig Party nominee for lieutenant governor on a ticket with John J. Crittenden, famous for the Crittenden Compromise. The Whigs won the general election and Helm was elevated to governor on July 31, 1850, when Crittenden resigned to accept an appointment as United States Attorney General in President Millard Fillmore's cabinet. After his service as governor Helm became president of the struggling Louisville and Nashville Railroad. He invested thousands of dollars of his own money in the project and convinced residents along the line's main route to buy stock in the company. In 1859 the line was completed, but the next year Helm resigned over of differences with the board of directors regarding a proposed branch that would extend the line to Memphis, Tennessee.
Document 4: Tennessee: Confederates held East Tennessee despite the strength of Unionist sentiment there, with the exception of extremely pro-Confederate Sullivan County. The Confederates, led by General James Longstreet, did attack General Burnside's Fort Sanders at Knoxville and lost. It was a big blow to East Tennessee Confederate momentum, but Longstreet won the Battle of Bean's Station a few weeks later. The Confederates besieged Chattanooga during the Chattanooga Campaign in early fall 1863, but were driven off by Grant in November. Many of the Confederate defeats can be attributed to the poor strategic vision of General Braxton Bragg, who led the Army of Tennessee from Perryville, Kentucky to another Confederate defeat at Chattanooga.
Document 5: Battle of Shiloh: The Battle of Shiloh, also known as the Battle of Pittsburg Landing, was a major battle in the Western Theater of the American Civil War, fought April 6 -- 7, 1862, in southwestern Tennessee. A Union force known as the Army of the Tennessee under Major General Ulysses S. Grant had moved via the Tennessee River deep into Tennessee and was encamped principally at Pittsburg Landing, Tennessee on the west bank of that river, where the Confederate Army of Mississippi, under General Albert Sidney Johnston and second - in - command P.G.T. Beauregard, launched a surprise attack on Grant's army from its base in Corinth, Mississippi. Johnston was mortally wounded during the fighting; Beauregard, who thus succeeded to command of the army, decided against pressing the attack late in the evening. Overnight Grant was reinforced by one of his own divisions stationed further north and was joined by three divisions from another Union army under Maj. Gen. Don Carlos Buell. This allowed them to launch an unexpected counterattack the next morning which completely reversed the Confederate gains of the previous day.
Document 6: Tennessee: During the American Revolutionary War, Fort Watauga at Sycamore Shoals (in present-day Elizabethton) was attacked (1776) by Dragging Canoe and his warring faction of Cherokee who were aligned with the British Loyalists. These renegade Cherokee were referred to by settlers as the Chickamauga. They opposed North Carolina's annexation of the Washington District and the concurrent settling of the Transylvania Colony further north and west. The lives of many settlers were spared from the initial warrior attacks through the warnings of Dragging Canoe's cousin, Nancy Ward. The frontier fort on the banks of the Watauga River later served as a 1780 staging area for the Overmountain Men in preparation to trek over the Appalachian Mountains, to engage, and to later defeat the British Army at the Battle of Kings Mountain in South Carolina.
Document 7: Confederate States Army: Some soldiers also deserted from ideological motivations. A growing threat to the solidarity of the Confederacy was dissatisfaction in the Appalachian mountain districts caused by lingering unionism and a distrust of the slave power. Many of their soldiers deserted, returned home, and formed a military force that fought off regular army units trying to punish them. North Carolina lost 23% of its soldiers (24,122) to desertion. The state provided more soldiers per capita than any other Confederate state, and had more deserters as well.
Document 8: Knoxville Confederate order of battle: The following Confederate States Army units and commanders fought in the Knoxville Campaign and subsequent East Tennessee operations during the American Civil War from November 4 to December 31, 1863 under the command of Lt. Gen. James Longstreet. Engagements of this campaign include the Battle of Dandridge and the Battle of Bean's Station. Order of battle compiled from the army organization during the campaign. The Union order of battle is shown separately.
Document 9: Samuel Snowden Hayes: Samuel Snowden Hayes (December 25, 1820 – January 28, 1880) was an American politician from Tennessee. Hayes moved to Illinois after a family tragedy and eventually established a successful law practice in Carmi. He became a prominent politician in White County, serving two terms in the Illinois House of Representatives and attending the 1848 state constitutional convention. He was a staunch supporter of the Democratic Party and often campaigned on their behalf. He moved to Chicago, Illinois in 1850 and became one of the city's leading Democratic voices preceding the Civil War. From 1858, he supported Stephen A. Douglas and championed him at the 1860 Democratic National Convention. He was one of the three delegates on the United States Revenue Commission in 1865.
Document 10: Tennessee: In February 1861, secessionists in Tennessee's state government—led by Governor Isham Harris—sought voter approval for a convention to sever ties with the United States, but Tennessee voters rejected the referendum by a 54–46% margin. The strongest opposition to secession came from East Tennessee (which later tried to form a separate Union-aligned state). Following the Confederate attack upon Fort Sumter in April and Lincoln's call for troops from Tennessee and other states in response, Governor Isham Harris began military mobilization, submitted an ordinance of secession to the General Assembly, and made direct overtures to the Confederate government. The Tennessee legislature ratified an agreement to enter a military league with the Confederate States on May 7, 1861. On June 8, 1861, with people in Middle Tennessee having significantly changed their position, voters approved a second referendum calling for secession, becoming the last state to do so.
Document 11: William Graham Swan: William Graham Swan (1821 – April 12, 1869) was an American attorney and politician active primarily in East Tennessee during the mid-19th century. Swan served in the Confederate States Congress during the American Civil War, and served one term as mayor of Knoxville, Tennessee, from 1855 until late 1856. He also helped establish the town of East Knoxville (later annexed by Knoxville), and served as its first mayor in the late 1850s. In 1854, Swan and his brother-in-law, Joseph Mabry, donated the initial land for the formation of Market Square in downtown Knoxville.
Document 12: North Carolina: Confederate troops from all parts of North Carolina served in virtually all the major battles of the Army of Northern Virginia, the Confederacy's most famous army. The largest battle fought in North Carolina was at Bentonville, which was a futile attempt by Confederate General Joseph Johnston to slow Union General William Tecumseh Sherman's advance through the Carolinas in the spring of 1865. In April 1865, after losing the Battle of Morrisville, Johnston surrendered to Sherman at Bennett Place, in what is today Durham. North Carolina's port city of Wilmington was the last Confederate port to fall to the Union, in February 1865, after the Union won the nearby Second Battle of Fort Fisher, its major defense downriver.
Document 13: Alfred O. P. Nicholson: Nicholson was born near Franklin, Tennessee, in Williamson County. He attended the University of North Carolina at Chapel Hill, graduating in 1827. He studied law and was admitted to the bar in 1831, opening a law practice in Columbia, Tennessee. He edited the "Western Mercury", a paper then published in Columbia, from 1832 to 1835. He also served in the Tennessee House of Representatives from 1833 to 1839. In 1840 he was appointed, on an interim basis, to succeed to the U.S. Senate seat vacated by the death of Senator Felix Grundy. He served in that office from December 25, 1840, to February 7, 1842. From 1843 to 1845 he served in the Tennessee State Senate, moving to Nashville during this period, and edited the "Nashville Union" from 1844 to 1846. From 1846 to 1847 he served as a director, and then as president, of the Bank of Tennessee.
Document 14: William Selden: According to the Library of Virginia "William Selden was born 31 January 1791 in Henrico County, Virginia, to Miles Selden (1752-1811) and Elizabeth Armistead Selden (1752-1833). He was a member for Henrico County in the House of Delegates from 1813 to 1816 and from 1818 to 1821. He later served as Registrar of the Land Office. He married first Maria Eliza Swann (d. 1834) 26 November 1833, and they had one child. He married second Emily Hunter 9 June 1840, and they had eight children. Selden died 7 April 1874."
Document 15: Tennessee: Many major battles of the American Civil War were fought in Tennessee—most of them Union victories. Ulysses S. Grant and the U.S. Navy captured control of the Cumberland and Tennessee rivers in February 1862. They held off the Confederate counterattack at Shiloh in April. Memphis fell to the Union in June, following a naval battle on the Mississippi River in front of the city. The Capture of Memphis and Nashville gave the Union control of the western and middle sections; this control was confirmed at the Battle of Murfreesboro in early January 1863 and by the subsequent Tullahoma Campaign.
