During the U.S. Civil War, two battles were fought at Bull Run, and both were Confederate victories. The First and Second Battles of Bull Run were fought in Manassas, Va., and are also known as the First and Second Battle of Manassas.
On July 21, 1861, the Battle of Bull Run marked the first battlefield confrontation between the Union and Confederate armies. The fierce fighting proved that the war was not going to be easily won by either side. The following year, the two armies were more experienced and clashed from August 28-30, 1862. General Robert E. Lee had taken over command of the Confederate troops and soundly defeated Union Major General John Pope.
