29-30 August, 1862: Confederate General Robert E. Lee’s army defeats the army of Union General John Pope at the Second Battle of Manassas (2nd Bull Run). This was another significant tactical victory for the Confederates and was another blow to Union morale. Union casualties were about 14,000 killed and wounded out of 62,000 engaged; the Confederates lost about 1,000 killed and 7,000 wounded out of 50,000. At one point in the fighting, a line of Confederates who were low on ammunition began to hurl stones at the advancing northern troops and managed to successfully hold them off until more southern reinforcements arrived to help push back the union advance.
