Beardslee Telegraph
The Beardslee Telegraph was a portable military telegraph developed by George Beardslee and adopted by Albert J. Myer to provide a mobile field telegraph system. The instrument was operated by hand-turned magnetos and did not require the heavy batteries needed in the civilian telegraphs. It included an alphabet dial and pointer instead of the usual key for transmission.Boatner p. 53 Limitations of the instrument were its short range of about ten miles due to insufficient power, slow transmission, and frequent lack of synchronization between sending and receiving sets. It was first used 24 May 1862 in the Peninsular campaign. Its first major triumph was during the Battle of Fredericksburg when it provided Ambrose E. Burnside, Burnside with communications across the river when fog and smoke had rendered the usual visual signal communication impossible.Boatner p. 54 Its popularity declined after this battle because it was often competing with the faster and more powerful commercial t ...

Telegraph
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined and such systems are thus not true telegraphs. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling. Th ...

Battle Of Fredericksburg
The Battle of Fredericksburg was fought December 11–15, 1862, in and around Fredericksburg, Virginia, in the Eastern Theater of the American Civil War. The combat, between the Union Army of the Potomac commanded by Maj. Gen. Ambrose Burnside and the Confederate Army of Northern Virginia under Gen. Robert E. Lee, included futile frontal attacks by the Union army on December 13 against entrenched Confederate defenders along the Sunken Wall on the heights behind the city. It is remembered as one of the most one-sided battles of the war, with Union casualties more than twice as heavy as those suffered by the Confederates. A visitor to the battlefield described the battle as a "butchery" to U.S. President Abraham Lincoln. Burnside's plan was to cross the Rappahannock River at Fredericksburg in mid-November and race to the Confederate capital of Richmond before Lee's army could stop him. Bureaucratic delays prevented Burnside from receiving the necessary pontoon bridges in time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ambrose E
Ambrose of Milan ( la, Aurelius Ambrosius; ), venerated as Saint Ambrose, ; lmo, Sant Ambroeus . was a theologian and statesman who served as Roman Catholic Archdiocese of Milan, Bishop of Milan from 374 to 397. He expressed himself prominently as a public figure, fiercely promoting the Christian faith against Arianism and paganism. He left a substantial collection of writings, of which the best known include the ethical commentary ''De officiis ministrorum'' (377–391), and the exegetical (386–390). His preachings, his actions and his literary works, in addition to his innovative musical hymnography, made him one of the most influential ecclesiastical figures of the 4th century. Ambrose was serving as the Roman governor of Emilia (region of Italy), Aemilia-Liguria in Milan when he was unexpectedly made Bishop of Milan in 374 by popular acclamation. As bishop, he took a firm position against Arianism and attempted to mediate the conflict between the emperors Theodosius I an ...

Magneto
A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current. Unlike a dynamo, a magneto does not contain a commutator to produce direct current. It is categorized as a form of alternator, although it is usually considered distinct from most other alternators, which use field coils rather than permanent magnets. Hand-cranked magneto generators were used to provide ringing current in telephone systems. Magnetos were also adapted to produce pulses of high voltage in the ignition systems of some gasoline-powered internal combustion engines to provide power to the spark plugs. Use of such ignition magnetos for ignition is now limited mainly to engines without a low-voltage electrical system, such as lawnmowers and chainsaws, and to aircraft engines, in which keeping the ignition independent of the rest of the electrical system ensures that the engine continues running in the event of alternator or battery failure. For redundancy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Equipment Of The American Civil War
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
