Eight months later, Union General George McClellan took command of union forces in Washington and began another mission to Richmond, where he engaged the enemy. After several battles in which neither side could claim victory, McClellan began withdrawing his forces back towards Washington.
With several famous Confederate Soldiers involved, such as Robert E. Lee and Stonewall Jackson, a major battle erupted at Manassas again. The battle raged for two days, with the Confederates once again repulsing the Union Army, sending them retreating under darkness back to Washington. There were reports of casualties numbering around 10,000 for the Union forces and 8,300 for the Confederates.
