his cavalry under Sheridan to destroy the Virginia Central Railroad near Charlottesville. Third, he planned a stealthy operation to withdraw from Lee's front and move across the James River. He planned to cross to the south bank of the river, bypassing Richmond, and isolate the capital by seizing the railroad junction of Petersburg to the south. Lee reacted to the first two actions as Grant had hoped. He pulled Breckinridge's division from Cold Harbor and sent it toward Lynchburg to parry Hunter. By June 12 he followed this by assigning Jubal Early permanent command of the Second Corps and sending them to the Valley as well. And he sent two of his three cavalry divisions in pursuit of Sheridan, leading to the Battle of Trevilian Station. On June 9, Meade ordered the construction of a new line of entrenchments in the army's rear, extending northward from Elder Swamp to Allen's Mill Pond. On June 11, the construction was complete and he issued orders for a movement to the James River, beginning after dark on June 12. (Also on June 11, Lee ordered Early's Second Corps to depart for Charlottesville, likewise on June 12.) As night fell on June 12, Hancock's II Corps and Wright's VI Corps took up positions on the new entrenchment line. Warren's V Corps cleared the roads heading south, advancing over Long Bridge and White Oak Swamp Bridge, taking up a blocking position just east of Riddell's Shop, facing toward Richmond while Burnside's IX Corps and Smith's XVIII Corps withdrew from the original line of entrenchments. The cavalry brigade of Col. George H. Chapman, part of Brig. Gen. James H. Wilson's division, which did not accompany Sheridan on his raid, screened the roads heading toward Richmond. Burnside headed south, followed by Wright and Hancock. Smith's XVIII Corps marched to White House, where on the morning of June 13 they embarked on steamers for Bermuda Hundred. They arrived at Point of Rocks on the Appomattox River the night of June 14. While Lee remained unaware of Grant's intentions, Union army engineers constructed the longest pontoon bridge of the war. It stretched over deep water, crossing the James from Weyanoke to Windmill Point at Flowerdew Hundred. Work started at 4 p.m. on June 15 and was completed seven hours later. Although most of Grant's infantry crossed the river by boats, the IX Corps, one division of VI Corps, the
