After the defeat of the Army of the Potomac during the Seven Days fighting, Gen. Jackson's 2nd Corps of the Army of Northern Virginia moved north to capture the Federal supply depot at Manassas Junction. The Union Army of Virginia, under Gen. Pope, moved south to intercept the Confederate force. On the afternoon of August 9th, 1862, Union forces under Gen. Banks intercepted the lead elements of Jackson's troops at Cedar Mountain near Culpepper, Virginia.
