Potomac. Grant's objectives remained the same although he thought it unlikely the Confederates would be drawn into open battle. Lee's orders Confederate General-in-chief Robert E. Lee, who was already concerned about the ability of his weakening army to maintain the defense of Petersburg and Richmond, realized that the Confederate defeat at Fort Stedman would encourage Grant to make a move against his right flank and communication and transportation routes. On the morning of March 29, 1865, Lee prepared to send some reinforcements to the western end of his line and began to form a mobile force of about 10,600 infantry, cavalry and artillery under the command of Major General George Pickett and cavalry commander Major General Fitzhugh Lee. This force would go beyond the end of the line to protect the key junction at Five Forks in Dinwiddie County from which a Union force could access the remaining open Confederate roads and railroads. Union troop movements Before dawn on March 29, 1865, Warren's V Corps moved west of the Union and Confederate lines while Sheridan's cavalry took a longer, more southerly route toward Dinwiddie Court House.

Gregory and Colonel (Brevet Brigadier General) Alfred L. Pearson, who was later awarded the Medal of Honor, drove the Confederates back to their White Oak Road Line. Casualties for both sides were nearly even at 381 for the Union and 371 for the Confederates. After the battle, Griffin's division moved up to occupy the
