ガバヌーア・ウォーレン
Late on July 4, Meade held a council of war in which his corps commanders agreed that the army should remain at Gettysburg until Lee acted, and that the cavalry should pursue Lee in any retreat. Meade decided to have Brig. Gen. Gouverneur K. Warren take a division from Sedgwick's VI Corps to probe the Confederate line and determine Lee's intentions. By the morning of July 5, Meade learned of Lee's departure, but he hesitated to order a general pursuit until he had received the results of Warren's reconnaissance.
