Lee, having ascertained by the night of June 28 that McClellan was in retreat, ordered Magruder the next day in immediate pursuit along the Williamsburg Road and York River Railroad. Magruder played a passive role, having been informed by Lee that Jackson would help "push the pursuit vigorously". Without Jackson or reinforcements from Huger, Magruder cautiously engaged at Savage's Station with the Union's rear guard, "satisfied just to maintain the fight and position" against a force that outnumbered his own nearly 2-to-1, and concluded fighting with no significant outcome. Late that evening Lee reprimanded him: "I regret very much that you made so little progress today in the pursuit of the enemy. In order to reap the benefits of our victory the pursuit should be most vigorous. I must urge you then to press on his rear rapidly and steadily".
