Union (American Civil War)
During the American Civil War, the Union, also known as the North, referred to the United States led by President Abraham Lincoln. It was opposed by the secessionist Confederate States of America (CSA), informally called "the Confederacy" or "the South". The Union is named after its declared goal of preserving the United States as a constitutional union. "Union" is used in the U.S. Constitution to refer to the founding formation of the people, and to the states in union. In the context of the Civil War, it has also often been used as a synonym for "the northern states loyal to the United States government;" in this meaning, the Union consisted of 20 free states and five border states. The Union Army was a new formation comprising mostly state units, together with units from the regular U.S. Army. The border states were essential as a supply base for the Union invasion of the Confederacy, and Lincoln realized he could not win the war without control of them, especially Maryla ...

Battle Of The Crater
The Battle of the Crater was a battle of the American Civil War, part of the siege of Petersburg. It took place on Saturday, July 30, 1864, between the Confederate Army of Northern Virginia, commanded by General Robert E. Lee, and the Union Army of the Potomac, commanded by Major General George G. Meade (under the direct supervision of the general-in-chief, Lieutenant General Ulysses S. Grant). After weeks of preparation, on July 30 Union forces exploded a mine in Major General Ambrose E. Burnside's IX Corps sector, blowing a gap in the Confederate defenses of Petersburg, Virginia. At that point, everything deteriorated rapidly for the Union attackers. Unit after unit charged into and around the crater, where most of them milled in confusion in the bottom of the crater. Grant considered this failed assault as "the saddest affair I have witnessed in this war." The Confederates quickly recovered, and launched several counterattacks led by Brigadier General William Mahone. The bre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by other names) was a civil war in the United States. It was fought between the Union ("the North") and the Confederacy ("the South"), the latter formed by states that had seceded. The central cause of the war was the dispute over whether slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Decades of political controversy over slavery were brought to a head by the victory in the 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. An initial seven southern slave states responded to Lincoln's victory by seceding from the United States and, in 1861, forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. Led by Confederate President Jefferson Davis, ...

Regiment
A regiment is a military unit. Its role and size varies markedly, depending on the country, service and/or a specialisation. In Medieval Europe, the term "regiment" denoted any large body of front-line soldiers, recruited or conscripted in one geographical area, by a leader who was often also the feudal lord ''in capite'' of the soldiers. Lesser barons of knightly rank could be expected to muster or hire a company or battalion from their manorial estate. By the end of the 17th century, infantry regiments in most European armies were permanent units, with approximately 800 men and commanded by a colonel. Definitions During the modern era, the word "regiment" – much like "corps" – may have two somewhat divergent meanings, which refer to two distinct roles: # a front-line military formation; or # an administrative or ceremonial unit. In many armies, the first role has been assumed by independent battalions, battlegroups, task forces, brigades and other, similarly s ...
