The Battle of Chancellorsville was a major battle of the American Civil War (1861–1865), and the principal engagement of the Chancellorsville campaign. It was fought from April 30 to May 6, 1863, in Spotsylvania County, Virginia, near the village of Chancellorsville. Two related battles were fought nearby on May 3 in the vicinity of Fredericksburg. The campaign pitted Union Army Maj. Gen. Joseph Hooker's Army of the Potomac against an army less than half its size, General Robert E. Lee's Confederate Army of Northern Virginia.
The Second Battle of Bull Run or Battle of Second Manassas was fought August 29–30, 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 Army of the Potomac was the principal Union Army in the Eastern Theater of the American Civil War. It was created in July 1861 shortly after the First Battle of Bull Run and was disbanded in June 1865 following the surrender of the Confederate Army of Northern Virginia in April.
Jackson's Valley campaign, also known as the Shenandoah Valley campaign of 1862, was Confederate Maj. Gen. Thomas J. "Stonewall" Jackson's spring 1862 campaign through the Shenandoah Valley in Virginia during the American Civil War. Employing audacity and rapid, unpredictable movements on interior lines, Jackson's 17,000 men marched 646 miles (1,040 km) in 48 days and won several minor battles as they successfully engaged three Union armies, preventing them from reinforcing the Union offensive against Richmond.
The Battle of Cross Keys was fought on June 8, 1862, in Rockingham County, Virginia, as part of Confederate Army Maj. Gen. Thomas J. "Stonewall" Jackson's campaign through the Shenandoah Valley during the American Civil War. Together, the battles of Cross Keys and Port Republic the following day were the decisive victories in Jackson's Valley Campaign, forcing the Union armies to retreat and leaving Jackson free to reinforce Gen. Robert E. Lee for the Seven Days Battles outside Richmond, Virginia.
The Battle of Cedar Mountain, also known as Slaughter's Mountain or Cedar Run, took place on August 9, 1862, in Culpeper County, Virginia, as part of the American Civil War. Union forces under Maj. Gen. Nathaniel P. Banks attacked Confederate forces under Maj. Gen. Thomas J. "Stonewall" Jackson near Cedar Mountain as the Confederates marched on Culpeper Court House to forestall a Union advance into central Virginia. After nearly being driven from the field in the early part of the battle, a Confederate counterattack broke the Union lines resulting in a Confederate victory. The battle was the first combat of the Northern Virginia campaign.
The Army of Virginia was organized as a major unit of the Union Army and operated briefly and unsuccessfully in 1862 in the American Civil War. It should not be confused with its principal opponent, the Confederate Army of Northern Virginia, commanded by Robert E. Lee.
Culp's Hill, which is about 3⁄4 mi (1,200 m) south of the center of Gettysburg, Pennsylvania, played a prominent role in the Battle of Gettysburg. It consists of two rounded peaks, separated by a narrow saddle. Its heavily wooded higher peak is 630 ft (190 m) above sea level. The lower peak is about 100 feet shorter than its companion. The eastern slope descends to Rock Creek, about 160 feet lower in elevation, and the western slope is to a saddle with Stevens Knoll with a summit 100 ft (30 m) lower than the main Culp's Hill summit. The hill was owned in 1863 by farmer Henry Culp and was publicized as "Culp's Hill" by October 31, 1865.
The XII Corps was a corps of the Union Army during the American Civil War.
The Maryland campaign occurred September 4–20, 1862, during the American Civil War. Confederate Gen. Robert E. Lee's first invasion of the North 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 single-day battle in American history.

The 2nd Regiment Massachusetts Volunteer Infantry was an infantry regiment in the Union Army during the American Civil War. Major George H. Gordon, a West Point graduate and veteran of the Mexican-American War, organized the unit's recruitment and formation. The 2nd Massachusetts was trained at Camp Andrew in West Roxbury, Massachusetts on the site of the former Transcendentalist utopian community, Brook Farm. Roughly half the regiment was mustered in on May 18, 1861 and the remainder on May 25, 1861 for a term of three years. The regiment saw extensive combat as part of the Army of the Potomac particularly during the Battle of Antietam and the Battle of Gettysburg.
The 125th Pennsylvania Infantry volunteered during the American Civil War and served a 9-month term from August 1862 to May 1863. It selected the motto In God We Trust. The Regiment fought at the Battle of Antietam under the leadership of Colonel Jacob C. Higgins less than six weeks after being recruited in Blair, Cambria and Huntingdon Counties. The Regiment was noted for its charge through the East Woods, along the Great Cornfield, down Smoketown Road, past the Dunker Church, and into the West Woods. While in formation beyond the Dunker Church in an 'overextended' position, the Regiment repulsed four counterattacks at a price of 229 casualties within 20 minutes. A fifth, heavily reinforced Confederate counterattack forced a retreat with a desperate struggle to retain the Regimental colors. Two weeks before the end of their enlistment, the 125th Pennsylvania also occupied the perimeter of Chancellorsville, Virginia, during the Battle of Chancellorsville.
