Document 2: Battle of Gettysburg: The Battle of Gettysburg ( , with an sound) was fought July 1–3, 1863, in and around the town of Gettysburg, Pennsylvania, by Union and Confederate forces during the American Civil War. The battle involved the largest number of casualties of the entire war and is often described as the war's turning point. Union Maj. Gen. George Meade's Army of the Potomac defeated attacks by Confederate Gen. Robert E. Lee's Army of Northern Virginia, halting Lee's invasion of the North.
Document 3: Battle of Monocacy: The Battle of Monocacy (also known as Monocacy Junction) was fought on July 9, 1864, approximately 6 mi from Frederick, Maryland, as part of the Valley Campaigns of 1864 during the American Civil War. Confederate forces under Lt. Gen. Jubal A. Early defeated Union forces under Maj. Gen. Lew Wallace. The battle was part of Early's raid through the Shenandoah Valley and into Maryland in an attempt to divert Union forces away from Gen. Robert E. Lee's army under siege at Petersburg, Virginia. The battle was the northernmost Confederate victory of the war. While the Union troops retreated to Baltimore, Maryland, the Confederates continued toward Washington, D.C., but the battle at Monocacy delayed Early's march for a day, allowing time for Union reinforcements to arrive in the Union capital. The Confederates launched an attack on Washington on July 12 at the Battle of Fort Stevens, but were unsuccessful and retreated to Virginia.
Document 4: Seven Days Battles: The Seven Days Battles were a series of six major battles over the 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.

Document 6: Hale-Byrnes House: The Hale-Byrnes House is a historic home located at 606 Stanton-Christiana Road, Stanton, New Castle County, Delaware. It was built in 1750, and is a two-story, five bay brick dwelling. The house was built by Samuel Hale, who sold it to Daniel Byrnes in 1754. The house gained historic stature after the Battle of Cooch's Bridge, the only Revolutionary War battle in Delaware. After the skirmish General George Washington held a council at the house on September 6, 1777.
Document 7: Gettysburg Campaign: The Gettysburg Campaign was a military invasion of Pennsylvania by the main Confederate army under General Robert E. Lee in summer 1863. The Union won a decisive victory at Gettysburg July 1–3, with heavy casualties on both sides. Lee managed to escape back to Virginia with most of his army. It was a turning point in the American Civil War, with Lee increasingly pushed back toward Richmond until his surrender in April 1865. After his victory in the Battle of Chancellorsville, Lee's Army of Northern Virginia moved north for a massive raid designed to obtain desperately needed supplies, to undermine civilian morale in the North, and to encourage anti-war elements. The Union Army of the Potomac was commanded by Maj. Gen. Joseph Hooker and then (from June 28) by Maj. Gen. George G. Meade.
Document 8: George Armstrong Custer: Custer developed a strong reputation during the Civil War. He participated in the first major engagement, the First Battle of Bull Run on July 21, 1861, near Washington, D.C. His association with several important officers helped his career as did his success as a highly effective cavalry commander. Custer was brevetted to brigadier general at age 23, less than a week before the Battle of Gettysburg, where he personally led cavalry charges that prevented Confederate cavalry from attacking the Union rear in support of Pickett's Charge. He was wounded in the Battle of Culpeper Court House in Virginia on September 13, 1863. In 1864, Custer was awarded another star and brevetted to major general rank. At the conclusion of the Appomattox Campaign, in which he and his troops played a decisive role, Custer was present at General Robert E. Lee's surrender to General Ulysses S. Grant, on April 9, 1865.
Document 9: Pennsylvania Route 97 (Adams County): Pennsylvania Route 97 (PA 97) is a state highway in the U.S. state of Pennsylvania. Known for most of its length as Baltimore Pike, the highway runs 9.363 mi from the Maryland state line near Littlestown, where the highway continues as Maryland Route 97 (MD 97), northwest to U.S. Route 15 (US 15) near Gettysburg. PA 97 connects Gettysburg and Littlestown in southeastern Adams County. The highway also links those communities with Westminster and Baltimore. From PA 97's northern end, Baltimore Pike continues toward Gettysburg through the Gettysburg Battlefield Historic District, where it provides access to the Gettysburg Museum and Visitor Center.
Document 10: Northern Virginia Campaign: 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.
Document 11: Battle of Chancellorsville: 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. Chancellorsville is known as Lee's "perfect battle" because his risky decision to divide his army in the presence of a much larger enemy force resulted in a significant Confederate victory. The victory, a product of Lee's audacity and Hooker's timid decision making, was tempered by heavy casualties, including Lt. Gen. Thomas J. "Stonewall" Jackson. Jackson was hit by friendly fire, requiring his left arm to be amputated; he died of pneumonia eight days later, a loss that Lee likened to losing his right arm.
Document 12: Brush Creek Salems Church: Brush Creek Salems Church, now known as Irwin Brush Creek Salem United Church of Christ, is a historic Reformed church building located in Hempfield Township, Westmoreland County, Pennsylvania. It was built between 1816 and 1820, and is a two-story, brick building with a gable roof. The interior features a second floor gallery. A connected gable roofed, one-story addition was built in 1958.
Document 13: Savage's Station, Virginia: Savage's Station was the wartime name of a supply depot, ammunition dump, field hospital, and command headquarters of the Army of the Potomac during the Peninsula Campaign of the American Civil War. Savage's Station was located in Henrico County, Virginia on what was the Richmond and York River Railroad, however the historical department of the Norfolk Southern Railroad, the railroad track's current owner, has no record that an actual train station or station house ever existed on the property. A farmhouse is known to have been located in a copse of trees on a small knoll next to the railroad track and is visible in several period drawings and photographs made during the war. The house served as the nucleus of a large field hospital during and after the battle of Seven Pines and the Seven Days Battles. The house also functioned as General George B. McClellan's headquarters during the battle of Savage's Station on June 29, 1862. Although the house survived the battle in 1862, it was burned by Federal cavalry under General Philip H. Sheridan in 1864. The house appears to have never been rebuilt, and no trace of it remains today. However, a smokehouse from the 19th century still existed on the property as late as the 1930s when it was photographed during a survey of local historical structures as a project of the Civilian Conservation Corps. The smokehouse fell into ruin and collapsed sometime prior to the 1980s. A small brick-walled cemetery from the 18th century still sits near the former location of the house not far from the railroad track.
Document 14: Creek Meeting House and Friends' Cemetery: Creek Meeting House and Friends' Cemetery is a historic Society of Friends meeting house and cemetery on Salt Point Turnpike/Main Street in Clinton Corners, Dutchess County, New York. It was built between 1777 and 1782. The meeting house is a two story, squarish building constructed of fieldstone. Land for the building was given by Able Peters whose substantial brick house is the next building on the same side of the road north of the meeting house. In 1828 the Friends Creek Meeting split into Hicksite and Orthodox meetings (Orthodox referring to mainstream Protestant practices). The Orthodox meeting moved about a mile north of Clinton Corners to the Shingle Meeting House] located on the grounds of the current Friends Upton Lake Cemetery. The Creek Meeting sold the building to the Upton Lake Grange in 1927 and joined the Bulls Head Meeting in 1936. The Grange transferred the building to the Town of Clinton Historical Society in 1995. The original slate covered, moderately pitched gable roof was replaced with metal in the early 21st century by the Historical Society.
Document 15: Nichol's Gap Road: The Nichol's Gap Road was a central Pennsylvania highway established in the 18th century near Maryland extending westward from the Black's Gap Road "just west of Little Conewago Creek" at the "Crofs Keys" stand of James Black. The road was past both the Rock Creek Church and 1761 Samuel Gettys tavern where Gettysburg would be surveyed in 1786. The highway was built over the South Mountain (Maryland and Pennsylvania) via Nichol's Gap ( ) and down the Devils Racecourse into the Cumberland Valley, allowing access to the 1762 Hagerstown, Maryland. Called the "Hagerstown Road" during the Battle of Gettysburg, parts of the road are now designated (east-to-west): U. S. Route 30 in Pennsylvania, Pennsylvania Route 116 (Fairfield Road to Fairfield, Pennsylvania), Iron Springs Road, Gum Springs Road, and Old Route 16 (the summit section through Nichol's Gap--"Fairfield Gap" during the American Civil War—no longer has a roadway.)
