Second Manassas - Longstreet's Assault - August 30, 1862
Civil War Trust’s map of the Battle of Second Manassas - Longstreet’s Assault
In the aftermath of the General Fitz John Porter’s failed attack on the Deep Cut on August 30, the Union Fifth Corps was in utter disarray. Making matters worse, Federal commander General John Pope was still unaware that a fresh body of 28,000 Confederates under General James Longstreet had arrived on the field and were poised to deliver a crushing blow to the disorganized Union left. And that is exactly what Longstreet did. In the largest simultaneous mass assault of the war, Longstreet’s forces crushed the Union left flank and the Federals were driven back to Bull Run. Only an effective Union rearguard action prevented a replay of the First Manassas disaster thirteen months earlier. Pope’s retreat to Centreville was precipitous, nonetheless. The next day, General Robert E. Lee ordered his army in pursuit. This was the decisive battle of the Northern Virginia Campaign.
