By 9:00 a.m., Wright realized that there was little more his corps could do at the Hatcher's Run end of the line and that Humphrey's II Corps was moving against this sector of the Confederate line in any event. At about the same time, Thomas Harris's brigade learned of Wright's general advance. When the XXIV Corps followed the VI Corps' advance, Major General Ord sent an engineer, Lieutenant Colonel Peter S. Michie, to find a location for a defensive line in the event the Confederates counterattacked. Instead, Michie ordered Ord's troops forward when he saw the VI Corps' accomplishment, leading to the meeting of Ord and Gibbon with Wright. When Wright met Ord and Gibbon in the Confederate works, they decided that since the Confederate defense had collapsed, they would turn their combined force toward the city. By about 10:00 a.m., Ord and Wright were moving 15,000 men in a line facing northeast, with Ord on the right and Wright on the left as they advanced toward the city with the idea of attempting to break the western defenses of Petersburg. As the VI Corps approached the Whitworth house near the Appomattox River, Major General Gibbon's XXIV Corps was allowed to pass them and lead the move toward the city. The VI Corps deployed in support of the XXIV Corps but instead of being able to rest, the troops on the north end of the line would have to deal with Confederate artillery fire protecting Lee's headquarters at the Turnbull House on Edge Hill.
