The Battle of Antietam ( an-TEE-təm), or Battle of Sharpsburg particularly in the Southern United States, was a battle of the American Civil War fought on September 17, 1862, between Confederate Gen. Robert E. Lee's Army of Northern Virginia and Union Gen. George B. McClellan's Army of the Potomac near Sharpsburg, Maryland, and Antietam Creek. Part of the Maryland Campaign, it was the first field army–level engagement in the Eastern Theater of the American Civil War to take place on Union soil. It remains the bloodiest day in American history, with a combined tally of 22,727 dead, wounded, or missing. Although the Union Army suffered heavier casualties than the Confederates, the battle was a major turning point in the Union's favor. After pursuing Confederate Gen. Robert E. Lee into Maryland, Maj. Gen. George B. McClellan of the Union Army launched attacks against Lee's army who were in defensive positions behind Antietam Creek. At dawn on September 17, Maj. Gen. Joseph Hooker's corps mounted a powerful assault on Lee's left flank. Attacks and counterattacks swept across Miller's Cornfield, and fighting swirled around the Dunker Church. Union assaults against the Sunken Road eventually pierced the Confederate center, but the Federal advantage was not followed up. In the afternoon, Union Maj. Gen. Ambrose Burnside's corps entered the action, capturing a stone bridge over Antietam Creek and advancing against the Confederate right. At a crucial moment, Confederate Maj. Gen. A. P. Hill's division arrived from Harpers Ferry and launched a surprise counterattack, driving back Burnside and ending the battle. Although outnumbered two-to-one, Lee committed his entire force, while McClellan sent in less than three-quarters of his army, enabling Lee to fight the Federals to a standstill. During the night, both armies consolidated their lines. In spite of crippling casualties, Lee continued to skirmish with McClellan throughout September 18, while removing his battered army south of the Potomac River. McClellan successfully turned Lee's invasion back, making the battle a Union victory, but President Abraham Lincoln, unhappy with McClellan's general pattern of overcaution and his failure to pursue the retreating Lee, relieved McClellan of command in November. From a tactical standpoint, the battle was somewhat inconclusive; the Union Army successfully repelled the Confederate invasion but suffered heavier casualties and failed to defeat Lee's army outright. However, it was a significant turning point in the war in favor of the Union due in large part to its political ramifications: the battle's result gave Lincoln the political confidence to issue the Emancipation Proclamation, declaring all "persons held as slaves within any State, or designated part of a State, the people whereof shall then be in rebellion," as of the first of the following year, shall be "forever free." This effectively discouraged the British and French governments from recognizing the Confederacy, as neither power wished to give the appearance of supporting slavery.

Hagerstown Valley is located in Maryland in the United States. It is part of the Great Appalachian Valley, which continues northward as Cumberland Valley in Pennsylvania, and southward as Shenandoah Valley in West Virginia and Virginia. Hagerstown Valley is bounded on the east by South Mountain, part of the Blue Ridge Mountains. On the west the valley is bounded by the Bear Pond Mountains — a range of mountains linking Blue Mountain and North Mountain. The valley is bounded on the south by the Potomac River and on the north by the drainage divide between Conococheague Creek, which flows south to the Potomac River, and Conodoguinet Creek, which flows northeast to the Susquehanna River. Sometimes the boundary between Hagerstown Valley and Cumberland Valley is defined politically, as the state line between Maryland and Pennsylvania. The political definition restricts Hagerstown Valley to Washington County, Maryland, while the larger definition includes part of Franklin County, Pennsylvania as well. Sometimes Cumberland Valley is defined so as to include Hagerstown Valley entirely, extending south all the way to the Potomac River. Antietam Creek flows through Hagerstown Valley to the Potomac River. Antietam National Battlefield is also in the valley, where the Battle of Antietam was fought during the American Civil War. The main cities are Hagerstown, Maryland and Waynesboro, Pennsylvania. The water divide between Hagerstown and Cumberland valleys occurs near the city of Chambersburg, Pennsylvania.
