Colorbearer

After his stunning victory at Second Manassas Aug. 28-30, 1862, Confederate Gen. Robert E. Lee decided to seize the initiative, relieve Virginia and threaten Washington by marching north. In early September, Lee led his ragged army of 55,000 across the Potomac River at White's Ford near Leesburg. By Sept. 7, the Confederate army was marching into Frederick.

An alarmed Union Gen. George McClellan, restored to command of the primary Federal army, pulled together disorganized and defeated Union forces and pursued. Lee hoped the citizens of Maryland would rally to his army, welcoming his "invasion" as they would a liberator. Instead, few helped or joined his forces. Nevertheless, Lee continued north, concentrating at Hagerstown for a possible march into Pennsylvania.

Among Lee's concerns were Union garrisons threatening his communication and supply lines behind him at Harpers Ferry and Martinsburg.

The Confederate commander divided his army to take care of the problem. He sent Stonewall Jackson and others south to neutralize Harpers Ferry. Other Confederates moved west across South Mountain, then north toward Hagerstown.

As Lee's troops scattered, McClellan's amry moved into Frederick. The Union commander got a break. A copy of Lee's orders outlining his army's division - the famous Special Order 191 - was found in a newly abandoned Confederate camp south of Frederick near the Monocacy River. McClellan moved quickly. Hoping to catch Lee before he could reunite his army, the Federal commander drove toward South Mountain. Confederates put up a fight there Sept. 14, occupying the gaps and buying time for Lee to gather strength.

The Union garrison at Harpers Ferry surrendered Sept. 15. Lee ordered Jackson and others to return quickly as the Confederate commander desperately tried to concentrate near Sharpsburg. McClellan, after brushing aside resistance at South Mountain, bore down with vastly superior forces.

Both armies maneuvered warily on Sept. 16. Then, on the misty early morning of Sept. 17, 1862, the armies collided. On the ridges above Sharpburg and along Antietam Creek, American soldiers met in the bloodiest day of the war.

Neither side gained a real advantage during the fighting that day, but a disappointed Lee eventually withdrew across the Potomac River at Shepherdstown, leaving a trail of wounded soldiers in public buildings and private homes.

Lee's adventures north of the Potomac were costly to both sides. Lee casualties totaled more than 13,000 men, McClellan lost twice as many including those captured at Harpers Ferry.

The Antietam Campaign Trail

Trails sign

A driving tour follows the routes of Union and Confederate soldiers in September 1862 as they marched through Maryland toward what would be the Battle of Antietam. The route begins with Robert E. Lee crossing the Potomac River into Maryland at Whites Ford, then moving quickly toward Frederick. Driving tour stops explore the cavalry and infantry action along the way. Several Trail stops in the Frederick area explain the reaction of the town to the soldiers' passing. After Frederick, the tour continues through Middletown to South Mountain. Tour stops at each gap highlight the fighting on Sept. 14, 1862. The driving tour continues to the Antietam battlefield.

Monocacy National Battlefield - Although most of the interpretation is devoted to the 1864 battle, the National Park does help explain the Confederate camps here in 1862 and the famous "Lost Order" found after Lee's infantry left.
