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. Union Major General George Meade's Army of the Potomac defeated attacks by Confederate General Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North and forcing his retreat.
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 Second Battle of Bull Run or Battle of Second Manassas was fought August 28–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run fought on July 21, 1861, on the same ground.
The Battle of Yorktown or siege of Yorktown was fought from April 5 to May 4, 1862, as part of the Peninsula Campaign of the American Civil War. Marching from Fort Monroe, Union Maj. Gen. George B. McClellan's Army of the Potomac encountered Maj. Gen. John B. Magruder's small Confederate force at Yorktown behind the Warwick Line. McClellan suspended his march up the Peninsula toward Richmond and settled in for siege operations.
The Peninsula campaign of the American Civil War was a major Union operation launched in southeastern Virginia from March to July 1862, the first large-scale offensive in the Eastern Theater. The operation, commanded by Major General George B. McClellan, was an amphibious turning movement against the Confederate States Army in Northern Virginia, intended to capture the Confederate capital of Richmond. Despite the fact that Confederate spy Thomas Nelson Conrad had obtained documents describing McClellan's battle plans from a double agent in the War Department, McClellan was initially successful against the equally cautious General Joseph E. Johnston, but the emergence of the more aggressive General Robert E. Lee turned the subsequent Seven Days Battles into a humiliating Union defeat.
The Battle of South Mountain, known in several early Southern accounts as the Battle of Boonsboro Gap, was fought on September 14, 1862, as part of the Maryland campaign of the American Civil War. Three pitched battles were fought for possession of three South Mountain passes: Crampton's, Turner's, and Fox's Gaps.
The Seven Days Battles were a series of seven battles over seven days from June 25 to July 1, 1862, near Richmond, Virginia, during the American Civil War. Confederate General Robert E. Lee drove the invading Union Army of the Potomac, commanded by Maj. Gen. George B. McClellan, away from Richmond and into a retreat down the Virginia Peninsula. The series of battles is sometimes known erroneously as the Seven Days Campaign, but it was actually the culmination of the Peninsula Campaign, not a separate campaign in its own right.
The Battle of Eltham's Landing, also known as the Battle of Barhamsville, or West Point, took place on May 7, 1862, in New Kent County, Virginia, as part of the Peninsula Campaign of the American Civil War. Brig. Gen. William B. Franklin's Union division landed at Eltham's Landing and was attacked by two brigades of Brig. Gen. G. W. Smith's command, reacting to the threat to the Confederate army's trains on the Barhamsville Road. Franklin's movement occurred while the Confederate army was withdrawing from the Williamsburg line, but he was unable to interfere with the Confederate movement.
The Battle of Seven Pines, also known as the Battle of Fair Oaks or Fair Oaks Station, took place on May 31 and June 1, 1862, in Henrico County, Virginia as part of the Peninsula Campaign of the American Civil War.
The Battle of Oak Grove, also known as the Battle of French's Field or King's School House, took place on June 25, 1862, in Henrico County, Virginia, the first of the Seven Days Battles of the American Civil War. Maj. Gen. George B. McClellan advanced his lines with the objective of bringing Richmond within range of his siege guns. Two Union divisions of the III Corps attacked across the headwaters of White Oak Swamp, but were repulsed by Maj. Gen. Benjamin Huger's Confederate division. McClellan, who was 3 miles (4.8 km) in the rear, initially telegraphed to call off the attack, but ordered another attack over the same ground when he arrived at the front. Darkness halted the fighting. Union troops gained only 600 yards (550 m), at a cost of over a thousand casualties on both sides.
The Battle of Beaver Dam Creek, also known as the Battle of Mechanicsville or Ellerson's Mill, took place on June 26, 1862, in Hanover County, Virginia. It was the first major engagement of the Seven Days Battles during the Peninsula Campaign of the American Civil War and the start of Confederate General Robert E. Lee's counter-offensive against the Union Army of the Potomac, under Maj. Gen. George B. McClellan, which threatened the Confederate capital of Richmond.
The Battle of Gaines' Mill, sometimes known as the Battle of Chickahominy River, took place on June 27, 1862, in Hanover County, Virginia, as the third of the Seven Days Battles which together decided the outcome of the Union's Peninsula Campaign of the American Civil War. Following the inconclusive Battle of Beaver Dam Creek (Mechanicsville) the previous day, Confederate General Robert E. Lee renewed his attacks against the right flank of the Union Army, relatively isolated on the northern side of the Chickahominy River. There, Brig. Gen. Fitz John Porter's V Corps had established a strong defensive line behind Boatswain's Swamp. Lee's force was destined to launch the largest Confederate attack of the war, about 57,000 men in six divisions. Porter's reinforced V Corps held fast for the afternoon as the Confederates attacked in a disjointed manner, first with the division of Maj. Gen. A.P. Hill, then Maj. Gen. Richard S. Ewell, suffering heavy casualties. The arrival of Maj. Gen. Stonewall Jackson's command was delayed, preventing the full concentration of Confederate force before Porter received some reinforcements from the VI Corps.
The Battle of Savage's Station took place on June 29, 1862, in Henrico County, Virginia, as the fourth of the Seven Days Battles of the American Civil War. The main body of the Union Army of the Potomac began a general withdrawal toward the James River. Confederate Brig. Gen. John B. Magruder pursued along the railroad and the Williamsburg Road and struck Maj. Gen. Edwin Vose Sumner's II Corps with three brigades near Savage's Station, while Maj. Gen. Thomas J. "Stonewall" Jackson's divisions were stalled north of the Chickahominy River. Union forces continued to withdraw across White Oak Swamp, abandoning supplies and more than 2,500 wounded soldiers in a field hospital.
John Bankhead Magruder often referred to as "Prince John Magruder", was an American and Confederate military officer. A graduate of West Point, Magruder served with distinction during the Mexican–American War (1846–1848) and was a prominent Confederate Army general during the American Civil War (1861–1865). As a major general, he received recognition for delaying the advance of Maj. Gen. George B. McClellan's Army of the Potomac, during the 1862 Peninsula Campaign, as well as recapturing Galveston, Texas the following year.
The Northern Virginia Campaign, also known as the Second Bull Run Campaign or Second Manassas Campaign, was a series of battles fought in Virginia during August and September 1862 in the Eastern Theater of the American Civil War. Confederate General Robert E. Lee followed up his successes of the Seven Days Battles in the Peninsula campaign by moving north toward Washington, D.C., and defeating Maj. Gen. John Pope and his Army of Virginia.
The Maryland campaign occurred September 4–20, 1862, during the American Civil War. The campaign was Confederate General Robert E. Lee's first invasion of the North. It was repulsed by the Army of the Potomac under Maj. Gen. George B. McClellan, who moved to intercept Lee and his Army of Northern Virginia and eventually attacked it near Sharpsburg, Maryland. The resulting Battle of Antietam was the bloodiest day of battle in American history.
Fort Magruder was a 30-foot-high (9.1 m) earthen fortification straddling the road between Yorktown and Williamsburg, Virginia, just outside the latter city during the American Civil War. At the center of the Williamsburg Line, it was also referred to as Redoubt Number 6.
The eastern theater of the American Civil War consisted of the major military and naval operations in the states of Virginia, West Virginia, Maryland, and Pennsylvania, the national capital in Washington, D.C., and the coastal fortifications and seaports of North Carolina. The interior of the Carolinas were considered part of the western theater, and other coastal areas along the Atlantic Ocean were part of the lower seaboard theater.
The 37th New York Infantry Regiment or the Irish Rifles was formed accepted by the State on May 25, 1861, and organized in New York City. The regiment mustered in the service of the United States on June 6 and 7, 1861 for two years of service to June 22, 1863.
The Battle of Malvern Hill, also known as the Battle of Poindexter's Farm, was fought on July 1, 1862, between the Confederate Army of Northern Virginia, led by Gen. Robert E. Lee, and the Union Army of the Potomac under Maj. Gen. George B. McClellan. It was the final battle of the Seven Days Battles during the American Civil War, taking place on a 130-foot (40 m) elevation of land known as Malvern Hill, near the Confederate capital of Richmond, Virginia and just one mile (1.6 km) from the James River. Including inactive reserves, more than fifty thousand soldiers from each side took part, using more than two hundred pieces of artillery and three warships.
