Sheridan was prepared to move against the Confederates with his cavalry on March 30, but heavy rains lasting from the evening of March 29 until the morning of the 31st made a large-scale movement impracticable over the unpaved roads. During the storm he kept his horses around Dinwiddie. On the last day of the month a portion of Sheridan’s forces which had pushed northwest toward Five Forks were engaged by Southern forces who succeeded in driving them back toward the main Union troop concentration at Dinwiddie Court House. Pickett, the Confederate leader, then found his men badly outnumbered and withdrew them to Five Forks without pressing the advantage he had gained. This incident, often called the Battle of Dinwiddie Court House, was a minor Confederate victory, although Sheridan’s men were neither demoralized nor disorganized by the attack, and Lee could find small comfort in the situation. Lee was able to concentrate on his right only about 10,600 cold and hungry Confederates to meet the expected Union drive to turn his right flank. Massed against him at this part of the line were more than 10,000 Northern cavalry and 43,000 infantry. The desperate urgency of Lee’s fears was indicated in the dispatch he sent to Pickett early on April 1, the day of the struggle for Five Forks. “_Hold Five Forks at all hazards._ Protect road to Ford’s Depot and prevent Union forces from striking the south-side railroad. Regret exceedingly your forced withdrawal, and your inability to hold the advantage you had gained.” [Illustration: _A Union Army wagon train entering Petersburg._ Courtesy, National Archives.] Throughout April 1, Pickett’s troops worked unceasingly, erecting barricades of logs, branches, and earth around Five Forks. At about 4 p. m., with only 2 hours of daylight remaining, Sheridan’s cavalry and Warren’s infantry attacked. While the dismounted cavalry charged the Confederates from the front of their newly erected defense line, two divisions of foot soldiers from the V Corps drove around to the left of Pickett’s troops and, after crossing the White Oak Road which connected Five Forks with Petersburg, hit them on the weakly held left flank. Lacking sufficient artillery support, the Southerners were quickly overcome. Realizing that their position was no longer tenable, portions of the Confederate troops tried to retreat to Petersburg, but the avenue of escape had been cut by the Union advance across the White Oak Road. By dusk, the Battle of Five Forks had ended. Union troops were in possession of the disputed area. They had cut off and captured over 3,200 prisoners, while suffering a loss which was probably less than 1,000. Now the besieging forces had nearly succeeded in accomplishing Grant’s objective of encircling the city. The western extremity of Lee’s defenses had crumbled.
