The Civil War in Marion County

Sweeden's Cove, the Chattanooga Campaign, and the bushwhacker war on the plateau

Marion County's Civil War story is shaped by location. The county sits on the southern edge of the Cumberland Plateau, straddles the Tennessee River, and lies on the main corridor between Nashville and Chattanooga. That placement made it a crossroads for troop movements, raids, and skirmishes throughout the war, and it made the county's rugged plateau and gorge country fertile ground for guerrilla fighting once conventional armies had passed through.

Divided loyalties

Like much of East Tennessee, Marion County held strong Unionist sentiment alongside Confederate support. The county did not rely on a plantation-and-slavery economy to the extent the western parts of the state did, and many Sequatchie Valley families sent sons to both armies. The division cut through neighborhoods and, in some cases, through single households. Bushwhacker violence in the later years of the war was often personal as much as strategic.

Battle of Sweeden's Cove, June 4, 1862

Sweeden's Cove, also spelled Sweeten's Cove, sits about seven miles north of South Pittsburg. On June 4, 1862 it was the site of a sharp cavalry engagement, the first significant combat on Marion County soil during the war.

Sweeden's Cove was the 79th Pennsylvania's first engagement of the war. For the Union command the victory opened the way for Negley's subsequent raid toward Chattanooga. For Marion County, it set the pattern of the war locally: fast cavalry engagements along the valley, not set-piece battles. Who is actually buried at Bean-Roulston is one of the county's enduring Civil War mysteries; no complete identification of those graves has ever been published. Read more about Sweeten's Cove →

The Chattanooga Campaign, 1863

The war came closest to Marion County in the fall of 1863, during the Chattanooga Campaign. The major set-piece battles, Lookout Mountain ("the Battle Above the Clouds," November 24) and Missionary Ridge (November 25), were fought just east of Marion County in Hamilton County, but the county sat squarely on the supply and maneuver lines of both armies.

Confederates under Braxton Bragg used Tennessee River crossings near the Marion County stretch of the river. Union General Joseph Hooker's command moved through the Lookout Valley and Wauhatchie area to reach Lookout Mountain. After the Confederate defeat at Missionary Ridge, Federal forces controlled the Tennessee River corridor through Marion County for the remainder of the war.

The siege of Chattanooga that followed Chickamauga in September was broken by the Cracker Line, an eight-day operation in late October 1863 that ran through western Marion County. Brig. Gen. William F. Smith's plan seized a bridgehead at Brown's Ferry on October 27, Hooker's XI and XII Corps marched east from Bridgeport through Lookout Valley and repelled a Confederate night attack at the Battle of Wauhatchie on October 28 to 29, and on October 29 the transport steamer Chattanooga made the first run from Bridgeport up the Tennessee River to Kelley's Ferry on the south bank of the river in western Marion County. Wagons carried rations the short overland distance from the landing over Raccoon Mountain to Brown's Ferry, where a pontoon bridge crossed into the besieged town. The narrow ferry crossing in western Marion County, named for 19th-century settler John Kelly, was for a few weeks one of the single most important supply points in the western theater of the war.

The 780-foot timber trestle at Whiteside, which carried the Nashville & Chattanooga Railroad over the Running Water ravine on Raccoon Mountain, was a critical link in the Federal supply line into Chattanooga. U.S. Military Railroads photographer George N. Barnard documented the rebuilt trestle on January 8, 1864; the resulting image is among the earliest surviving photographs of Marion County.

Raids, guerrillas, and bushwhackers

The rugged plateau and river gorge country that defined Marion County's geography also defined its irregular war. Bushwhacker raids, cavalry sweeps, and retaliatory violence between Unionist and Confederate partisans persisted through 1864 and into 1865, particularly along Battle Creek and in the coves of the Cumberland escarpment. Civilian families in Unionist-sympathizing pockets lived under constant threat of raid and retaliation. The bushwhacker war is less well documented than the conventional campaigns but was in many ways more devastating to local civilians.

Aftermath

Reconstruction-era Marion County was poor and depopulated. Many farms had been stripped of livestock, fencing, and labor; young men on both sides were dead or scattered. Recovery depended heavily on the arrival of the railroad and the capital-intensive iron, coal, and coke operations that would transform the county in the 1870s and 1880s, an industrial boom funded largely by British capital that could not have taken root until peace returned.
