context_page_description: The Second Battle of Bull Run or Battle of Second Manassas was fought August 29–30, 1862, in Prince William County, Virginia, as part of the American Civil War. It was the culmination of the Northern Virginia 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 fought on July 21, 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 strong concealed defensive positions on Stony Ridge and awaited the arrival of the wing of Lee's army commanded by Maj. Gen. James Longstreet. On August 28, 1862, Jackson attacked a Union column just east of Gainesville, at Brawner's Farm, resulting in a stalemate but successfully getting Pope's attention. On that same day, Longstreet broke through light Union resistance in the Battle of Thoroughfare Gap and approached the battlefield.
context_section_description: The Second Battle of Bull Run began on August 28 as a Federal column, under Jackson's observation just outside Gainesville, near the farm of the John Brawner family, moved along the Warrenton Turnpike. It consisted of units from Brig. Gen. Rufus King's division: the brigades of Brig. Gens. John P. Hatch, John Gibbon, Abner Doubleday, and Marsena R. Patrick, marching eastward to concentrate with the rest of Pope's army at Centreville. King was not with his division because he had suffered a serious epileptic attack earlier that day.
  Jackson, who had been relieved to hear earlier that Longstreet's men were on their way to join him, displayed himself prominently to the Union troops, but his presence was disregarded. Concerned that Pope might be withdrawing his army behind Bull Run to link up with McClellan's arriving forces, Jackson determined to attack. Returning to his position behind the tree line, he told his subordinates, "Bring out your men, gentlemen." At about 6:30 p.m., Confederate artillery began shelling the portion of the column to their front, John Gibbon's Black Hat Brigade (later to be named the Iron Brigade). Gibbon, a former artilleryman, responded with fire from Battery B, 4th U.S. Artillery. The artillery exchange halted King's column. Hatch's brigade had proceeded past the area and Patrick's men, in the rear of the column, sought cover, leaving Gibbon and Doubleday to respond to Jackson's attack. Gibbon assumed that, since Jackson was supposedly at Centreville (according to Pope), and having just seen the 14th Brooklyn of Hatch's Brigade reconnoiter the position, that these were merely horse artillery cannons from Jeb Stuart's cavalry. Gibbon sent aides out to the other brigades with requests for reinforcements, and sent his staff officer Frank A. Haskell to bring the veteran 2nd Wisconsin Infantry up the hill to disperse the harassing cannons. Gibbon met the 2nd in the woods saying, "If we can get you up there quietly, we can capture those guns."
  The 2nd Wisconsin, under the command of Col. Edgar O'Connor, advanced obliquely back through the woods the Federal column was passing through. When the 430 men emerged from the woods on John Brawner's farm they were quietly formed and advanced up the hill. Upon reaching the plateau, they deployed skirmishers who drove back Confederate skirmishers. They soon received a heavy volley into their right flank by 800 men of the fabled Stonewall Brigade, commanded by Col. William S. Baylor. Absorbing the volley from 150 yards (140 m), the 2nd Wisconsin did not waver, but replied with a devastating volley at the Virginians in Brawner's orchard. The Confederates returned fire when the lines were only 80 yards (73 m) apart. As units were added by both sides, the battle lines remained close together, a standup fight with little cover, trading mass volleys for over two hours. Jackson described the action as "fierce and sanguinary". Gibbon added his 19th Indiana. Jackson, personally directing the actions of his regiments instead of passing orders to the division commander, Maj. Gen. Richard S. Ewell, sent in three Georgia regiments belonging to Brig. Gen. Alexander R. Lawton's brigade. Gibbon countered this advance with the 7th Wisconsin. Jackson ordered Brig. Gen. Isaac R. Trimble's brigade to support Lawton, which met the last of Gibbon's regiments, the 6th Wisconsin.
  After Trimble's brigade entered the action, Gibbon needed to fill a gap in his line between the 6th Wisconsin and the rest of the Iron Brigade regiments. Doubleday sent in the 56th Pennsylvania and the 76th New York, who advanced through the woods and checked the new Confederate advance. These men arrived at the scene after dark and both Trimble and Lawton launched uncoordinated assaults against them. Horse artillery under Captain John Pelham was ordered forward by Jackson and fired at the 19th Indiana from less than 100 yards (91 m). The engagement ended around 9 p.m., with Gibbon's men slowly retreating backwards still firing, making their line at the edge of the woods. Doubleday's regiments retired to the
