Confederate lines. Those division commanders and Ord reported to Grant that their men could not see well enough to attack at night, deferring the general assault until about 40 minutes after its originally planned start time of 4:00 a.m. After the battle on the night of April 1, Fitzhugh Lee informed Robert E. Lee of the defeat and rout at Five Forks from Church's Crossing near the Ford Church's Road junction with the South Side Railroad where the remaining forces of Rooney Lee and Thomas Rosser joined him. The survivors of the Confederate infantry brigades moved north through the woods and fields to ford Hatcher's Run and move over the W. Dabney road to a position near the South Side Railroad. Lee sent Lieutenant General Richard H. Anderson with his infantry to help Pickett reorganize and hold the South Side Railroad. Breakthrough at Petersburg (April 2) Sixth Corps breakthrough As ordered by General Grant, at 10:00 p.m., Union artillery opened fire with 150 guns on the Confederate lines opposite the Union Army's Petersburg lines until 2:00 a.m. After careful planning, VI Corps commander Major General Horatio G.

The land between the lines of the two armies was clear of trees and had few natural obstacles except for some marshes near the left end of Wright's line. To the right of the point of attack were inundated areas and strong defenses. The Confederates had batteries sited every few hundred yards along their line. The capture of the Confederate picket line during the Battle of Jones's Farm on March 25, 1865, put the VI Corps close enough to the main Confederate line, with a covered approach to within of the defenses, for the attack to succeed. Wright had about 14,000 troops to attack about 2,800 defenders over about of line. Forming for mass attack just behind the Union picket line, Wright's entire corps was placed in a wedge formation about wide. Brigadier General (Brevet Major General) George W. Getty's Second Division was in the middle front and in advance of the other two brigades for the assault while Brigadier General (Brevet Major General) Frank Wheaton's First Division was on the right rear and Brigadier General Truman Seymour's Third Division was on the left rear.
