full_context: Document 1: 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.

Document 2: Plastic shopping bag: The Dixie Bag Company of College Park, Georgia, owned and operated by Jack W. McBride, was one of the first companies to exploit this new opportunity to bring convenient products to all major shopping stores. The Dixie Bag Company, along with similar firms such as Houston Poly Bag and Capitol Poly, was instrumental in the manufacturing, marketing and perfecting of plastic bags in the 1980s. Kroger, a Cincinnati - based grocery chain, began to replace its paper shopping bags with plastic bags in 1982, and was soon followed by its rival, Safeway.
Document 3: 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 4: 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 5: Burning Man: To comply with the new requirements and to manage the increased liability load, the organizers formed Black Rock City, LLC. Will Roger Peterson and Flynn Mauthe created the Department of Public Works (DPW) to build the ``city ''grid layout (a requirement so that emergency vehicles could be directed to an`` address'') designed by Rod Garrett, an architect. Rod continued as the city designer until his death, in 2011, at the age of 76. He is also credited with the design of all of the man bases from 2001 through 2012, the center camp cafe and first camp. With the success of the driving ban, having no vehicular incidents, 1998 saw a return to the Black Rock desert, along with a temporary perimeter fence. The event has remained there since.

As director of the East Tennessee, Virginia and Georgia Railway (ETV&G), McGhee was responsible for much of the railroad construction that took place in the East Tennessee area in the 1870s and 1880s. His position with the railroad also gave him access to northern capital markets, which he used to help finance dozens of companies in and around Knoxville. In 1885, he established the Lawson McGhee Library, which was the basis of Knox County's public library system.
Document 13: 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.
Document 14: 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 15: 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.
