Second Battle Of Manassas
On August 30, 1862, the Second Battle of Manassas ended a long campaign in northern Virginia.
The campaign had begun when Union forces attempting to invade the Southern capital at Richmond were defeated just miles from the city. After the defeat near Richmond, the scattered Union forces under Major General John Pope clashed repeatedly with the Southern troops under Major General "Stonewall" Jackson. At the August 9 Battle of Cedar Mountain, Jackson's Confederates outnumbered the Union troops two-to-one. After his easy victory there, Jackson retired from the field as Union reinforcements arrived.
While Pope's Union army was engaged in fighting against General Robert E. Lee's forces along the Rappahannock River, Jackson attempted to maneuver around to Pope's rear in order to cut off his supply lines.
Weary from inconclusive fighting along the Rappahannock, Pope decided to concentrate his forces and march on Jackson, who had succeeded in cutting off Pope's supplies. A race was on for Pope to find and destroy Jackson before Lee could march his men to Jackson's aid.
The Second Battle of Bull Run, or, as it was called by the Confederacy, the Battle of Second Manassas, was fought August 28–30, 1862, as part of the American Civil War. It was the culmination of an offensive campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia against Union Maj. Gen. John Pope's Army of Virginia, and a battle of much larger scale and numbers than the First Battle of Bull Run (First Manassas) fought in 1861 on the same ground.
Following a wide-ranging flanking march, Confederate Maj. Gen. Thomas J. "Stonewall" Jackson captured the Union supply depot at Manassas Junction, threatening Pope's line of communications with Washington, D.C. Withdrawing a few miles to the northwest, Jackson took up defensive positions on Stony Ridge. On August 28, 1862, Jackson attacked a Union column just east of Gainesville, at Brawner's Farm, resulting in a stalemate. On that same day, the wing of Lee's army commanded by Maj. Gen. James Longstreet broke through light Union resistance in the Battle of Thoroughfare Gap and approached the battlefield.
28th started for Manassas, arriving there 29th. 30th and 31st were engaged in the battle—the troops behaving with great coolness, courage and in perfect order—about 11 oclock at night left the battle field, (being the last regiment that left and having the credit of saving the artillery.) and bivouak'd that night at Centreville. Left the latter place Sept. 1st at 5 a.m. arriving at Chantilly at dusk—here occuring a sharp engagement (Battle of Chantilly) lasting till 10 oclock at night. (It rained furiously, and the conflict was in the woods.) ”— Walt Whitman, Notebook #94, page 127. Walt Whitman Notebooks, 1847-1860s
