One hundred fifty years ago today was fought one of the most decisive battles of the Civil War: the Battle of Second Manassas. Fought on roughly the same battlefield as the war's first battle, it pitted the newly-formed Federal Army of Virginia against the Southern forces. General John Pope, who had seen success in the Western theater of the war, was arrogant and cocky, telling his new Eastern troops that in the West "we had always seen the backs of our enemies." Unfortunately for Pope, this time he was up against the Confederate's First Team, led by the redoubtable Robert E. Lee.
Pope's army was organized into three corps; the First Corps (formerly Fremont's) led by Major-General Franz Sigel, the Second Corps led by Major-General Nathaniel P. Banks, and the Third Corps led by the always-unlucky Major-General Irvin McDowell, the losing general in the First Battle of Manassas a year earlier.
Two months earlier, General Robert E. Lee had thwarted the Union Army of the Potomac (under General George B. McClellan) and its attempt to capture Richmond in a desperate fight known as the Seven Days Battles. With McClellen having retreated up the peninsula, Lee knew that he could not afford to let the two armies come together, which would create a force that would greatly outnumber his own. Lee decided his best chance would be to go north and kick the crap out of Pope, then deal with McClellan later.
After defeating Banks's Corps at Ceder Mountain on Aug. 9, Stonewall Jackson took his troops (the Army of Northern Virginia was divided into two "wings" led by Jackson and General Longstreet) into Northern Virginia. Pope's army was increased to over 77,000 troops with the addition of reinforcements, particularly General Reno's two divisions sent up from Fredericksburg as well as divisions from the Army of the Potomac. Failing to find a weak spot in Pope's line, Lee decided to do a wide flanking maneuver around the Federal right, sending Jackson up to capture the supply depot at Manassas Junction, just thirty miles from Washington D.C. Pope was thoroughly confused, ordering his divisions here and there, clueless as to what Lee was up to. Realizing that Jackson was in Manassas, Pope thought he could trap Jackson and win a glorious battle. Jackson, greatly outnumbered and realizing his predicament, retreated a few miles to a strong defensive position at Sudley Mountain (Stony Ridge).
Jackson opened the battle by attacking General John Gibbon's Iron Brigade which was marching on the Warrenton Turnpike heading towards Manassas. It was a bloody but inconclusive fight since it was so late in the day, with neither side giving quarter. Pope, thinking that Jackson was going to retreat, planned on hitting Jackson's flanks on the next day, the 29th. Jackson, however, held a good defensive position on Stony Ridge with an unfinished railroad grade in front of his line, which was about two miles long, and Jackson's flanks were supported by Gen. Stuart's cavalry.
On the morning of August 29, 1862, the Federals attacked Jackson's line. The Confederate line was behind the railroad cuts and embankments, and repulsed the Federal attack. Although greatly outnumbered, Jackson held on throughout the day. Union General Fitz John Porter had been ordered by Pope to attack Jackson's right, but Porter found his way blocked by Confederate troops; unknown to Pope, it was Longstreet's entire force sitting patiently on Pope's flank, waiting for the opportune moment to strike.
Jackson's left had been pushed back by the relentless Union attack. Longstreet refused to attack, thinking that the time to hit the Federals had not yet arrived. Pope, under the delusion that the Confederates were about to retreat, did not realize that the entire Army of Northern Virginia was on the field. McClellan, just a few miles away with 25,000 troops, did not come to Pope's aid, for he wanted Pope to fail (what teamwork!)
The Union Army renewed its attack the next day. Jackson's men, running out of ammo, were reduced to hurling rocks at the attacking Federal troops. It was at this time that the opportune moment had arrived; Longstreet hit the Federal left with 25,000 troops. The clueless and luckless Pope, thinking he was about to secure a great victory, was now fighting for survival. It was only a determined defense by Gen. Reynolds around Henry House Hill, the famous landmark of First Manassas, that kept it from being a complete rout, allowing the Union Army to retreat to Centerville. The next day (Sept. 1) Lee tried to get his army between the Federals and Washington, but was stopped at the battle of Ox Hill. Pope was soon relieved of command and sent back west to fight Indians, and Lee decided to head north to a little town called Sharpsburg.
