Peninsula Campaign - Aftermath and The Seven Days

Aftermath and The Seven Days

Despite claiming victory at Seven Pines, McClellan was shaken by the experience. 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 and never regained it.

Lee used the month-long pause in McClellan's advance to fortify the defenses of Richmond and extend them south to the James River at Chaffin's Bluff. On the south side of the James River, defensive lines were built south to a point below Petersburg. The total length of the new defensive line was about 30 miles (48 km). To buy time to complete the new defensive line and prepare for an offensive, Lee repeated the tactic of making a small number of troops seem larger than they really were. McClellan was also unnerved by Jeb Stuart's audacious (but otherwise militarily pointless) cavalry ride completely around the Union army (June 13–15).

The second phase of the Peninsula Campaign took a negative turn for the Union when Lee launched fierce counterattacks just east of Richmond in the Seven Days Battles (June 25 – July 1, 1862). Although none of these battles were significant Confederate tactical victories (and the Battle of Malvern Hill on the last day was a significant Confederate defeat), the tenacity of Lee's attacks and the sudden appearance of Stonewall Jackson's "foot cavalry" on his western flank unnerved McClellan, who pulled his forces back to a base on the James River. Lincoln later ordered the army to return to the Washington, D.C., area to support Maj. Gen. John Pope's army in the Northern Virginia Campaign and the Second Battle of Bull Run. The Virginia Peninsula was relatively quiet until May 1864, when Maj. Gen. Benjamin Butler again invaded as part of the Bermuda Hundred Campaign.
