The Confederate army won the First Battle of Bull Run. It was fought on July 21, 1861 and was the first significant land battle in the American Civil War.
The First Battle of Bull Run, also known as First Manassas, was fought near Manassas Junction, Va. Around 35,000 Union troops marched from Washington, D.C. to attack 20,000 Confederate troops beside a small river called Bull Run. The Union troops were led by Brigadier General Irvin McDowell, who had been ordered by Lincoln to attack and open a way to Richmond. Lincoln believed this would bring a quick end to the war. The Confederate troops, led by General P.G.T. Beauregard, met the Union troops and outmaneuvered them on the battlefield. The Federals were forced to retreat. They lost 3,000 soldiers at Bull Run, while the Confederates lost 1,750 lives.
