1865. Their mission was to occupy Dinwiddie Court House, cut the Boydton Plank Road, Southside Railroad and Richmond and Danville Railroad and to outflank the Confederates on their western (right) flank at the end of their White Oak Road line southwest of Petersburg. Under revised orders, Warren sent Brigadier General (Brevet Major General) Charles Griffin's First Division north on the Quaker Road toward the intersection with the Boydton Plank Road and the end of the White Oak Road Line. Brigadier General Joshua Chamberlain's First Brigade led the advance. North on Quaker Road, across Rowanty Creek at the Lewis Farm, Chamberlain's men encountered the brigades of Brigadier Generals Henry A. Wise, William Henry Wallace and Young Marshall Moody which had been sent by Lieutenant General Richard H. Anderson and Major General Bushrod Johnson to turn back the Union advance. Chamberlain was wounded and almost captured during the ensuing back-and-forth battle. Chamberlain's brigade, reinforced by a four-gun artillery battery and regiments from the brigades of Colonel (Brevet Brigadier General) Edgar M. Gregory and Colonel (Brevet Brigadier General) Alfred L. Pearson, who was later awarded the Medal of Honor, drove the Confederates back to the White Oak Road Line. The Union force suffered 381 casualties; the Confederates suffered 371. After the battle, Griffin's division moved up to occupy the junction of the Quaker Road and Boydton Plank Road near the end of the White Oak Road Line. Late in the afternoon, Sheridan's cavalry occupied Dinwiddie Court House on the Boydton Plank Road without opposition. Union forces had cut the Boydton Plank Road in two places, were close to the end of the Confederate line and had a large force in a strong position to attack the crucial road junction at Five Forks in Dinwiddie County to which Lee was just sending defenders. The two remaining Confederate railroad connections with Petersburg and Richmond would be within the Union Army's grasp if they took Five Forks. Encouraged by the Confederate failure to press their attack at Lewis's Farm and their withdrawal to the White Oak Road Line, Grant expanded Sheridan's mission to a major offensive rather than just a railroad raid and a forced extension of the Confederate line. He wrote in his letter to Sheridan: "I now feel like ending the matter...." March 30, 1865 Dinwiddie Court House and Five Forks From the late afternoon on March 29 through March 30, 1865, the Union's
