why did the union exert pressure into tennessee
Tennessee in the American Civil War Tennessee was one of the most divided states in the country at the outset of the war. Before the bombardment of Fort Sumter, Tennessee was actually staunchly pro-Union, though there were still a few secessionist hot beds in the western portion of the state. The situation changed when Fort Sumter was bombarded and Lincoln made the call for 75,000 volunteers to suppress the rebellion. Tennesseans saw this as a threat to their "southern brethren," and the only real pockets of pro-Unionism came from the eastern portion of the state. In fact, Tennessee would furnish more troops for the Union than any other Confederate state, combined. However, over three times that number volunteered for the Confederacy. Interestingly, notable general Nathan Bedford Forrest voted against secession, but later fought for his state when it seceded.
Secession in the United States The most famous secession movement was the case of the Southern states of the United States. Secession from the United States was accepted in eleven states (and failed in two others). The seceding states joined together to form the Confederate States of America (CSA). The eleven states of the CSA, in order of secession, were: South Carolina (seceded December 20, 1860), Mississippi (seceded January 9, 1861), Florida (seceded January 10, 1861), Alabama (seceded January 11, 1861), Georgia (seceded January 19, 1861), Louisiana (seceded January 26, 1861), Texas (seceded February 1, 1861), Virginia (seceded April 17, 1861), Arkansas (seceded May 6, 1861), North Carolina (seceded May 20, 1861), and Tennessee (seceded June 8, 1861). Secession was declared by its supporters in Missouri and Kentucky, but did not become effective as it was opposed by their pro-Union state governments. This secession movement brought about the American Civil War. The position of the Union was that the Confederacy was not a sovereign nation—and never had been, but that "the Union" was always a single nation by intent of the states themselves, from 1776 onward—and thus that a rebellion had been initiated by individuals. Historian Bruce Catton described President Abraham Lincoln's April 15, 1861, proclamation after the attack on Fort Sumter, which defined the Union's position on the hostilities:
