Today in History: The First Battle of Bull Run

On this day (July 21) in 1861 the first major battle of the U.S. Civil War was fought at Bull Run/Manassas. The battle was a showcase of inexperienced, poorly trained troops on both sides. The union lost the battle and fled north, but the southern troops were too disorganized to pursue them and follow up on their victory. This is the battle that gave Stonewall Jackson his nickname, although there is some debate as to whether he was being complemented for his fortitude or denigrated for his unwillingness to advance and support other units.
