The Battle of Gettysburg was a three-day battle in the American Civil War fought between Union and Confederate forces between July 1 and July 3, 1863, in and around Gettysburg, Pennsylvania. The battle, which was won by the Union, is widely considered the Civil War's turning point, ending the Confederacy's aspirations to establish an independent nation. It was the Civil War's bloodiest battle, claiming over 50,000 combined casualties over three days.
Robert Edward Lee was a Confederate general during the American Civil War, toward the end of which he was appointed the overall commander of the Confederate States Army. He led the Army of Northern Virginia—the Confederacy's most powerful army—from 1862 until its surrender in 1865, earning a reputation as a skilled tactician.
The Battle of Chancellorsville, April 30 – May 6, 1863, was a major battle of the American Civil War (1861–1865), and the principal engagement of the Chancellorsville campaign.
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.
The Battle of the Wilderness was fought on May 5–7, 1864, during the American Civil War. It was the first battle of Lieutenant General Ulysses S. Grant's 1864 Virginia Overland Campaign against General Robert E. Lee and the Confederate Army of Northern Virginia. The fighting occurred in a wooded area near Locust Grove, Virginia, about 20 miles (32 km) west of Fredericksburg. Both armies suffered heavy casualties, nearly 29,000 in total, a harbinger of a war of attrition by Grant against Lee's army and, eventually, against the Confederate capital, Richmond, Virginia. The battle was tactically inconclusive, as Grant disengaged and continued his offensive.
George Gordon Meade was a United States Army Major General who commanded the Army of the Potomac during the American Civil War from 1863 to 1865. He fought in many of the key battles of the Eastern theater and defeated the Confederate Army of Northern Virginia led by General Robert E. Lee at the Battle of Gettysburg.
The Battle of Five Forks was fought on April 1, 1865, southwest of Petersburg, Virginia, around the road junction of Five Forks, Dinwiddie County, at the end of the Siege of Petersburg, near the conclusion of the American Civil War.
A commander-in-chief or supreme commander is the person who exercises supreme command and control over an armed force or a military branch. As a technical term, it refers to military competencies that reside in a country's executive leadership, a head of state, head of government, or other designated government official.
Henry Warner Slocum Sr., was a Union general during the American Civil War and later served in the United States House of Representatives from New York. During the war, he was one of the youngest major generals in the Army and fought numerous major battles in the Eastern Theater and in Georgia and the Carolinas. While commanding a regiment, a brigade, a division, and a corps in the Army of the Potomac, he saw action at First Bull Run, the Peninsula Campaign, Harpers Ferry, South Mountain, Antietam, and Chancellorsville.
Commandant is a title often given to the officer in charge of a military training establishment or academy. This usage is common in English-speaking nations. In some countries it may be a military or police rank. It is also often used to refer to the commander of a military prison or prison camp.
Gouverneur Kemble Warren was an American civil engineer and United States Army general during the American Civil War. He is best remembered for arranging the last-minute defense of Little Round Top during the Battle of Gettysburg and is often referred to as the "Hero of Little Round Top". His subsequent service as a corps commander and his remaining military career were ruined during the Battle of Five Forks, when he was relieved of command of the V Corps by Philip Sheridan, who claimed that Warren had moved too slowly. A post-war court of inquiry found that Sheridan's relief of Warren was unjustified.
A military staff or general staff is a group of officers, enlisted and civilian staff who serve the commander of a division or other large military unit in their command and control role through planning, analysis, and information gathering, as well as by relaying, coordinating, and supervising the execution of their plans and orders, especially in case of multiple simultaneous and rapidly changing complex operations. They are organised into functional groups such as administration, logistics, operations, intelligence, training, etc. They provide multi-directional flow of information between a commanding officer, subordinate military units and other stakeholders. A centralised general staff results in tighter top-down control but requires larger staff at headquarters (HQ) and reduces accuracy of orientation of field operations, whereas a decentralised general staff results in enhanced situational focus, personal initiative, speed of localised action, OODA loop, and improved accuracy of orientation.
Alfred Pleasonton was a United States Army officer and major general of volunteers in the Union cavalry during the American Civil War. He commanded the Cavalry Corps of the Army of the Potomac during the Gettysburg campaign, including the largest predominantly cavalry battle of the war, Brandy Station. In 1864, he was transferred to the Trans-Mississippi theater, where he defeated Confederate General Sterling Price in two key battles, including the Battle of Mine Creek, the second largest cavalry battle of the war, effectively ending the war in Missouri. He was the son of Stephen Pleasonton and younger brother of Augustus Pleasonton.
Mission-type tactics is a method of command and delegation where the military commander gives subordinate leaders a clearly-defined objective, high-level details such as a timeframe, and the forces needed to accomplish that objective. The subordinate leaders are given the planning initiative and freedom of execution: they decide on the methods to achieve the objective independently. This allows a high degree of flexibility at the operational and tactical levels of command, which allows for faster decision-making on the ground and frees the higher leadership from managing the tactical details to concentrate on the strategic picture. This may be contrasted with "Befehlstaktik" or command-type tactics.
During the second day of the Battle of Gettysburg Confederate Gen. Robert E. Lee attempted to capitalize on his first day's accomplishments. His Army of Northern Virginia launched multiple attacks on the flanks of the Union Army of the Potomac, commanded by Maj. Gen. George G. Meade. The assaults were unsuccessful, and resulted in heavy casualties for both sides.
In the practice of international law, command responsibility is the legal doctrine of hierarchical accountability for war crimes, whereby a commanding officer (military) and a superior officer (civil) is legally responsible for the war crimes and the crimes against humanity committed by his subordinates; thus, a commanding officer always is accountable for the acts of commission and the acts of omission of his soldiers.
The Irish Republican Army was a guerrilla army that fought the Irish War of Independence against Britain from 1919 to 1921. It saw itself as the legitimate army of the Irish Republic declared in 1919. The Anglo-Irish Treaty, which ended this conflict, was a compromise which abolished the Irish Republic, but created the self-governing Irish Free State, within the British Empire. The IRA was deeply split over whether to accept the Treaty. Some accepted, whereas some rejected not only the Treaty but also the civilian authorities who had accepted it. This attitude eventually led to the outbreak of the Irish Civil War in late June 1922 between pro- and anti-Treaty factions.
The Kyūjō incident was an attempted military coup d'état in the Empire of Japan at the end of the Second World War. It happened on the night of 14–15 August 1945, just before the announcement of Japan's surrender to the Allies. The coup was attempted by the Staff Office of the Ministry of War of Japan and many from the Imperial Guard to stop the move to surrender.
The Confederate Army of Northern Virginia began its Retreat from Gettysburg on July 4, 1863. Following General Robert E. Lee's failure to defeat the Union Army at the Battle of Gettysburg, he ordered a retreat through Maryland and over the Potomac River to relative safety in Virginia.
The Stavka of the Supreme Commander was the supreme headquarters of the Russian Imperial Army in the field during World War I until the demobilization of the army in March 1918.
