United States Military Railroad
The U.S. Military Railroad (USMRR) was established by the United States Department of War, United States War Department as a separate agency to operate any rail lines seized by the government during the American Civil War. An Act of Congress of 31 January 1862 authorized President Abraham Lincoln to seize control of the railroads and telegraph for military use in January 1862.Gable, ''Railroad Generalship'', p. 13. In practice, however, the USMRR restricted its authority to Southern rail lines captured in the course of the war. As a separate organization for rail transportation the USMRR is one of the predecessors of the modern United States Army Transportation Corps. History The American Civil War was the first war where railroads were a significant factor in moving troops and supplying forces in the field. The United States Military Railroad organization was established to coordinate this new capability for the Union Army. The USMRR organization benefited from the appointm ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick ...

Army Of The Cumberland
The Army of the Cumberland was one of the principal Union armies in the Western Theater during the American Civil War. It was originally known as the Army of the Ohio. History The origin of the Army of the Cumberland dates back to the creation of the Army of the Ohio in November 1861, under the command of Brig. Gen. Robert Anderson. The army fought under the name Army of the Ohio until Maj. Gen. William S. Rosecrans assumed command of the army and the Department of the Cumberland and changed the name of the combined entity to the Army of the Cumberland. When Rosecrans assumed command, the army and the XIV Corps were the same unit, divided into three "grand divisions" (wings) commanded by Alexander McCook (Right Wing), George H. Thomas (Center), and Thomas L. Crittenden (Left). General Order No. 168 was the order passed by the Union Army on October 24, 1862, that called for commissioning the XIV Corps into the Army of the Cumberland. The army's first significant combat under th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Rosecrans
William Starke Rosecrans (September 6, 1819March 11, 1898) was an American inventor, coal-oil company executive, diplomat, politician, and U.S. Army officer. He gained fame for his role as a Union general during the American Civil War. He was the victor at prominent Western Theater battles, but his military career was effectively ended following his disastrous defeat at the Battle of Chickamauga in 1863. Rosecrans graduated in 1842 from the United States Military Academy where he served in engineering assignments as well as a professor before leaving the Army to pursue a career in civil engineering. At the start of the Civil War, leading troops from Ohio, he achieved early combat success in western Virginia. In 1862 in the Western Theater, he won the battles of Iuka and Corinth while under the command of Maj. Gen. Ulysses S. Grant. His brusque, outspoken manner and willingness to quarrel openly with superiors caused a professional rivalry with Grant (as well as with Secretary ...

Army Of Tennessee
The Army of Tennessee was the principal Confederate army operating between the Appalachian Mountains and the Mississippi River during the American Civil War. It was formed in late 1862 and fought until the end of the war in 1865, participating in most of the significant battles in the Western Theater. History 1862 The army was formed on November 20, 1862, when General Braxton Bragg renamed the former Army of Mississippi and was divided into two corps commanded by Leonidas Polk and William J. Hardee. A third corps was formed from troops from the Department of East Tennessee and commanded by Edmund Kirby Smith; it was disbanded in early December after one of its two divisions was sent to Mississippi. The remaining division was assigned to Hardee's corps while Kirby Smith returned to East Tennessee. The army's cavalry was consolidated into a single command under Joseph Wheeler.

Interior Lines
Interior lines (as opposed to exterior lines) is a military term, derived from the generic term ''line of operation'' or ''line of movement''. The term "interior lines" is commonly used to illustrate, describe, and analyze the various possible routes (lines) of logistics, supply, recon, approach, attack, evasion, maneuver, or retreat of armed forces. Interior line strategies are based on the fact that lines of movement and communication within an enclosed area are shorter and safer than those on the outside. As the area held by a defensive force shrinks, the interior line advantage held by the defensive force increases. Skillful and comprehensive application of interior line tactics can, for a partially surrounded combat force, provide vital breathing space, greatly reduce time, effort, security, and secrecy of resupplies and redeployment, and decrease the number of casualties. These effects may have a great impact on morale and eventually prove decisive, as according to Napo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confederate Railroads In The American Civil War
The American Civil War was the first in which large armies depended heavily on railroads to bring supplies. For the Confederate States Army, the system was fragile and was designed for short hauls of cotton to the nearest river or ocean port. During the war, new parts were hard to obtain, and the system deteriorated from overuse, lack of maintenance, and systematic destruction by Union raiders. The outbreak of war had a depressing effect on the economic fortunes of the Confederate railroad industry. With the cotton crop being hoarded under the "King Cotton" theory, railroads lost their main source of income.Ramsdell, p. 795. Many were forced to lay off employees, and in particular, let go skilled technicians and engineers. Due to a general opinion that the war would not last long, initially Confederate rail operators did not seek, nor build, alternative sources of iron for rail construction and repair. Although railroad contracts to port towns had ceased, due to the combined effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange And Alexandria Railroad
The Orange and Alexandria Railroad (O&A) was a railroad in Virginia, United States. Chartered in 1848, it eventually extended from Alexandria to Gordonsville, with another section from Charlottesville to Lynchburg. The road played a crucial role in the American Civil War, saw the first of many mergers in 1867, and eventually became an important part of the modern-day Norfolk Southern rail system. Antebellum period The Virginia General Assembly issued a charter to the O&A on May 28, 1848, to run from Alexandria to Gordonsville. Construction began in 1850 and was completed in April 1854, when it connected with the Virginia Central Railroad in Orange County. Its longtime president was John S. Barbour Jr., a Virginia lawyer, part-time delegate and son of U.S. Representative John Strode Barbour. In 1854, the General Assembly granted the O&A the right to build southward from Charlottesville to Lynchburg. O&A paid for trackage rights over Virginia Central tracks from Gordonsville ...
