fighting ended. Aftermath Both sides claimed victory with roughly equal casualties, but neither side's accomplishment was impressive. George B. McClellan's advance on Richmond was halted and the Army of Northern Virginia fell back into the Richmond defensive works. Union casualties were 5,031 (790 killed, 3,594 wounded, 647 captured or missing) and Confederate 6,134 (980 killed, 4,749 wounded, 405 captured or missing), making it the second largest and bloodiest battle of the war to date after Shiloh eight weeks earlier. The battle was frequently remembered by the Union soldiers as the Battle of Fair Oaks Station because that is where they did their best fighting, whereas the Confederates, for the same reason, called it Seven Pines. Historian Stephen W. Sears remarked that its current common name, Seven Pines, is the most appropriate because it was at the crossroads of Seven Pines that the heaviest fighting and highest casualties occurred. A contemporary map drawn by private Julius Honore Bayol of the 5th Alabama Infantry Regiment, refers simply to the engagement as having occurred at the "Battlefield of 31st of May and 1st June, 62." Despite claiming victory, McClellan was shaken by the experience. He wrote to his wife, "I am tired of the sickening sight of the battlefield, with its mangled corpses & poor suffering wounded! Victory has no charms for me when purchased at such cost." He redeployed all of his army except for the V Corps south of the river, and although he continued to plan for a siege and the capture of Richmond, he lost the strategic initiative. Casey's division was unjustly blamed for the near-disaster, and McClellan had Casey removed from command. The hapless division would play no further role in the campaign, being relegated to guard duty at Harrison's Landing along the James River, and was left behind permanently on the peninsula after the Army of the Potomac returned to Washington D.C. in early August. An offensive begun by the new Confederate commander, Gen. Robert E. Lee, would be planned while the Union troops passively sat in the outskirts of Richmond. The Seven Days Battles of June 25 through July 1, 1862, drove the Union Army back to the James River and saved the Confederate capital. After taking command, Robert E. Lee embarked on a reorganization of the Confederate army, breaking up and reassigning some brigades, nominating replacements for dead and wounded officers, and removing two brigadiers,
