The morning of July 21st became clear to two generals planning to (get around/win in a battle) their fighter (against someone or something)’s left. Interfering with the success of theConfederate plan were (more than two, but not a lot of) communication failures and generallack of coordination between units. McDowell’s forces, on the other had, were interfered with/slowed down by a difficult plan that needed/demanded complex (making two or more things look the same or happen at the same time). Constant and repeated delays on themarch and effective scouting by the Confederates gave his movements away, and, worst ofall Patterson did not occupy Johnston’s Confederate forces attention in the west. McDowell’s forces began by shelling the Confederates across Bull Run. Others crossed at Sudley Cross and slowly made their way to attack the Confederate left side. At the same time asBeauregard sent small lack of interest/separations to handle what he thought was only an(object or action that interferes with mental focus), he also sent a larger group (of people) toexecute flanking a flanking movement of his own on the Union left. Fighting screamed and acted violently throughout the day as Confederate forces weredriven back, (even though there is the existence of) impressive efforts by Colonel ThomasJackson to hold important high ground at Henry House Hill, earning him the (fake name)”Stonewall.” Late in the afternoon, Confederate (strengthening items/rewards/supplies)including those arriving by rail from the Shenandoah Valley extended the Confederate lineand succeeded in breaking the Union right side. At the fight’s (exciting part of something)Virginia cavalry under Colonel James Ewell Brown “Jeb” Stuart arrived on the field andcharged into a confused mass of New Yorkers, sending them fleetly to the rear. The Federalretreat quickly broke down/got worse as narrow bridges, (changed from yes to no or from guilty to not guilty) wagons, and heavy big-gun fire added to the confusion. The terribleretreat was further stopped/interfered with by the groups of escaping onlookers who hadcome down from Washington to enjoy the sight to see. Although successful (in a battle or contest), Confederate forces were too disorganized to chase after. By July 22, the shatteredUnion army reached the safety of Washington. The Fight of Bull Run convinced the Lincolnmanagement and the North that the Civil War would be a long and expensive affair. McDowell was relieved of command of the Union army and replaced by Maj. Gen. George B. McClellan, who set about reorganizing and training the troops.
