After careful planning during the two preceding days, Wright had chosen to attack the Confederate line from the Jones house to the left end of his line opposite Union Forts Fisher and Welch. 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 near the Lead Works. 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.
