Maryland

Approximately 110,000 soldiers of the Union and Confederate armies fought along the banks of Antietam Creek in the bloodiest single-day battle in American history.

In 12 hours of fighting, approximately 23,000 men fell, either killed, wounded, or missing, forever scarring the landscape around the town of Sharpsburg. Established as the Antietam Battlefield Site in 1890, Antietam National Battlefield became a National Park Service landmark in 1933. The park grew from 33 acres in the 1890s to encompassing over 3,000 acres today. Some of the Civil War’s most recognizable landmarks now sit within its boundaries, including Dunker Church, Bloody Lane, and Burnside Bridge. The events that occurred across the fields and woodlots around Sharpsburg and along Antietam Creek bring hundreds of thousands of visitors to Antietam National Battlefield every year.

There were over 75 raids and battles that took place in Maryland during the Civil War, including ""Bloody Antietam""--the bloodiest day in American military history.

As a border state between the North and South during the Civil War, Maryland's loyalties were strong for both sides. The first casualties of the war occurred during the Baltimore Riot of April 19, 1861, when members of the 6th Massachusetts Regiment were attacked by Confederate supporters while traversing through the city on their way to protect Washington, DC, from attack. Ten days later, Maryland chose not to secede from the Union by a vote of 53-13. On September 17, 1862, near Sharpsburg, one of the largest and bloodiest battles of the Civil War took place at ""Bloody Antietam."" At the end of the day, nearly one in four men would be a casualty of the battle, making it the bloodiest day in American military history. There were over 75 skirmishes, raids, and major battles that took place in Maryland during the Civil War. Through vintage photographs, Maryland in the Civil War shares the state's rich military heritage.

While Antietam remains one the most famous engagements of the Civil War, history largely overlooks the lower end of the battlefield.

Only here did the Confederates use Antietam Creek as a barrier, so it was the only place where Union troops had to force their way across. Here the Union army waged its final attack, and the Confederates launched their last counterattack led by A.P. Hill’s division. It might as well have been a different battle entirely from the more famed northern field.

Using dozens of journals, diaries, newspaper accounts and reports, author Robert M. Dunkerly examines the action in detail and explores the gradual preservation of this oft-neglected portion of America’s bloodiest battle.

Join historian John Hoptak as he narrates the critical Battle of South Mountain, long overshadowed by the Battle of Antietam.

In September 1862, Robert E. Lee led the Army of Northern Virginia north of the Potomac River for the time as part of his Northern invasion, seeking a quick end to the war. Lee divided his army in three, sending General James Longstreet north to Hagerstown and Stonewall Jackson south to Harper's Ferry. It was at three mountain passes, referred to as South Mountain, that Lee's army met the Federal forces commanded by General George B. McClellan on September 14. In a fierce day-long battle spread out across miles of rugged, mountainous terrain, McClellan defeated Lee but the Confederates did tie up the Federals long enough to allow Jackson's conquest of Harper's Ferry.

They Didn’t Need to be There

It was a calm, moonless night in late April 1865. Robert E. Lee had surrendered. Abraham Lincoln was dead. Assassin John Wilkes Booth and accomplice David Herold, previously hiding in the swamps of Southern Maryland, had crossed the Potomac River to safety. The barge Black Diamond was anchored with the Potomac Flotilla near Blackistone Lighthouse, hoping to prevent that crossing and catch the perpetrators. All onboard were unaware that they were too late. The steamer Massachusetts was running downriver carrying U.S. soldiers back to their regiments. By dawn, the Black Diamond was on the bottom of the river, the Massachusetts was crippled and eighty-seven men were dead. Author Karen E. Stone reveals the story of a heroic pursuit turned tragic.

Just south of the Mason-Dixon Line, Frederick, Maryland, was poised at the crossroads of the Civil War.

Here, Confederate troops passed west to the Battles of Antietam and South Monocacy, while Union troops marched north to Gettysburg and south to raid the resources of the Shenandoah Valley. Both heroes and villains were made in the spired city, such as Dame Barbara Fritchie, who is said to defied General Jackson; General Jubal Early, who threatened to put the town to the torch; and the local doctors and nurses who cared for thousands of wounded soldiers. Join local historian John Schildt as he recounts the fascinating history of Frederick in the Civil War.
