text: Lee devised a complex plan to pursue and destroy McClellan's army. Longstreet's and A.P. Hill's divisions looped back toward Richmond and then southeast to the crossroads at Glendale, Holmes's division headed farther south, to the vicinity of Malvern Hill, and Magruder's division was ordered to move due east to attack the Federal rear guard. Stonewall Jackson, commanding three divisions, was to rebuild a bridge over the Chickahominy and head due south to Savage's Station, where he would link up with Magruder and deliver a strong blow that might cause the Union Army to turn around and fight during its retreat. McClellan's rear guard at Savage's Station consisted five divisions from Sumner's II Corps, Heintzelman's III Corps, and Franklin's VI Corps. McClellan considered his senior corps commander, Sumner, to be incompetent, so he appointed no one to command the rear guard.
  Initial contact between the armies occurred at 9 a.m. on June 29, a four-regiment fight about  west of Savage's Station, lasting for about two hours before disengaging. Meanwhile, Jackson was not advancing as Lee had planned. He was taking time to rebuild bridges over the Chickahominy and he received a garbled order from Lee's chief of staff that made him believe he should stay north of the river and guard the crossings. These failures of the Confederate plan were being matched on the Union side, however. Heintzelman decided on his own that his corps was not needed to defend Savage's Station, so he decided to follow the rest of the army without informing his fellow generals.
