Explanation: The First Battle of Bull Run (Manassas) was significant for many reasons. It was the first battle of the war and one of many ill-executed Union attempts on Richmond. Though Union troops seemed to be winning early in the battle, Confederate reinforcements turned the tide. The Union soldiers were eventually forced to retreat. It was also the battle which earned Thomas Jackson the nickname "Stonewall" when he refused to back down under Sherman's barrage.
