The Battle of Monocacy (also known as Monocacy Junction) was fought on July 9, 1864, approximately 6 miles (9.7 km) 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.

In May and June, as part of the Valley Campaigns of 1864, Union General-in-Chief Lt. Gen. Ulysses S. Grant planned a coordinated movement of troops against Confederates in Virginia. It was during this campaign that Lt. Gen. Jubal Early's Confederates defeated Union forces to open a path to Washington, D.C. After skirmishing with Maj. Gen. David Hunter's men outside of Lynchburg, Virginia, on June 17 and 18, Early increased his forces to nearly 16,000 men and continued to Martinsburg, West Virginia, where the outnumbered Union troops had evacuated the town. On June 19, a small Union force at Harpers Ferry, West Virginia, burned the bridge across the Potomac River.
