First Battle of Bull Run
On July 21, 1861, Union and Confederate armies clashed near Manassas Junction, Virginia, in the first major land battle of the American Civil War. It began when about 35,000 Union troops marched from the federal capital in Washington, D.C. to strike a Confederate force of 20,000 along a small river known as Bull Run. After fighting on the defensive for most of the day, the rebels rallied and were able to break the Union right flank, sending the Federals into a chaotic retreat towards Washington. The win shocked many people in the North, who realized the war would not be won as easily as they had hoped
