The Battle of Savage's Station took place on June 29, 1862, in Henrico County, Virginia, as the fourth of the Seven Days Battles (Peninsula Campaign) of the American Civil War. The main body of the Union Army of the Potomac began a general withdrawal toward the James River. Confederate Brig. Gen. John B. Magruder pursued along the railroad and the Williamsburg Road and struck Maj. Gen. Edwin Vose Sumner's II Corps (the Union rearguard) with three brigades near Savage's Station, while Maj. Gen. Thomas J. "Stonewall" Jackson's divisions were stalled north of the Chickahominy River. Union forces continued to withdraw across White Oak Swamp, abandoning supplies and more than 2,500 wounded soldiers in a field hospital.
The battle was a stalemate at the cost of about 1,500 casualties on both sides, plus 2,500 previously wounded Union soldiers who were left to be captured when their field hospital was evacuated. Stonewall Jackson eventually crossed the river by about 2:30 a.m. on June 30, but it was too late to crush the Union Army, as Lee had hoped. Most of the Army of the Potomac crossed White Oak Swamp Creek unmolested by noon on June 30. General Lee reprimanded Magruder in a dispatch: "I regret much that you have made so little progress today in the pursuit of the enemy. In order to reap the fruits of our victory that pursuit should be most vigorous. ... We must lose no more time or he will escape us entirely." However, the fault for the lost opportunity must be shared equally with the poor staff work at Lee's own headquarters and a less than aggressive performance by Jackson. The Seven Days continued with the much larger Battle of Glendale and the Battle of White Oak Swamp on June 30.
