Hancock was needed in the Po sector to help Barlow's withdrawal, which meant that Warren was left in charge of the Laurel Hill sector. Immediately upon Hancock's departure, Warren requested permission from Meade to attack Laurel Hill immediately, uncoordinated with the rest of Grant's attack, scheduled for 5 p.m. Warren was embarrassed by his performance the previous day and wanted to restore his reputation for aggressiveness. For reasons unexplained, Meade acceded to the request. At 4:00 PM, elements of the II and V Corps assaulted the Confederate trenches at Laurel Hill, which required them to move through a grove of gnarled, splintered dead pine trees. The attacks were beaten off with severe losses. Grant was thus forced to postpone his 5 p.m. coordinated assault until Warren could get his troops reformed.
