Bull Run (American Civil War).
Fought July 21, 1861, between 40,000 Federals under General M’Dowell, and 30,000 Confederates under General Beauregard. The Confederates occupied a position extending for about nine miles along the southern bank of the Bull Run, and an attempt to turn and drive in their left was at first successful, but, being rallied by General Beauregard, they assumed the offensive, and totally routed the Northerners, with a loss of 1,492 killed and wounded, 1,600 prisoners, and 28 guns. The Confederates lost 1,752.
