The Second Battle of Bull Run (August 28-30, 1862) was one of the most decisive battles fought during the Civil War, and it was also one of the most unlikely. Less than three months before the battle, Joseph E. Johnston's Army of Northern Virginia had been pushed back nearly all the way to Richmond by George B. McClellan's Army of the Potomac, so close that Union soldiers could see the church steeples of the Confederate capital. And yet, at the end of Second Manassas, Robert E. Lee's Army of Northern Virginia found itself in the field unopposed about 20 miles away from the Union capital of Washington D.C. How could such a remarkable reversal of fortunes take place so quickly?
After Lee succeeded the wounded Johnston, he pushed McClellan's Army of the Potomac away from Richmond and back up the Peninsula in late June, only to then swing his army north to face a second Union army, John Pope's Army of Virginia. Needing to strike out before the Army of the Potomac successfully sailed back to Washington and linked up with Pope's army, Lee daringly split his army to threaten Pope's supply lines, forcing Pope to fall back to Manassas to protect his flank and maintain his lines of communication. At the same time, it left half of Lee's army (under Stonewall Jackson) potentially exposed against the larger Union army until the other wing (under James Longstreet) linked back up. Thus, in late August 1862, the Army of Northern Virginia and the Army of Virginia found themselves fighting over nearly the exact same land the South and North fought over in the First Battle of Bull Run 13 months earlier.
When Pope's army fell back to Manassas to confront Jackson, his wing of Lee's army dug in along a railroad trench and took a defensive stance. The battle began with the Union army throwing itself at Jackson the first two days. But the concentration on Stonewall's men opened up the Union army's left flank for Longstreet's wing, which marched 30 miles in 24 hours to reach the battlefield by the late afternoon of August 29. Lee used Longstreet's wing on August 30 to deliver a devastating flank attack before enough reinforcements from the retreating Army of the Potomac reached the field, sweeping Pope's Army from Manassas and forcing the Union soldiers into yet another disorderly retreat from Manassas to Washington D.C., a scene all too reminiscent of the First Battle of Bull Run.
With Washington urging Burnside to advance against Lee, Burnside launched an ill fated operation across the Rappahannock River near Fredericksburg in December 1862. From December 12-13, Burnside struggled to get his army across the river while it was under fire from Confederates in Fredericksburg, and things only got worse when they did. Although the Union almost broke the Confederate lines in the south on December 13, they were ultimately repulsed, and the battle is mostly remembered for the piecemeal attacks the Union army made on heavily fortified positions Longstreet's men took up on Marye's Heights. As they threw themselves at Longstreet's heavily fortified position along the high ground, the Northern soldiers were mowed down again and again. General Longstreet compared the near continuous fall of soldiers on the battlefield to "the steady dripping of rain from the eaves of a house." During the battle, Lee turned to Longstreet and commented, "It is well that war is so terrible, otherwise we should grow too fond of it."
The Battle of Chancellorsville is one of the most famous of the Civil War, and the most famous part of the battle was Stonewall Jackson's daring march across the Army of the Potomac's flank, surprising the XI Corps with an attack on May 2, 1863. Having ignored warnings of...
