resulted in the extension of the lines. Fighting continued in bad weather on February 6 and 7 after which the Union force built trenches and fortifications to hold the extended line. The Confederates matched the Union works by extending their Boydton Plank Road Line to the south and their White Oak Road line to the west. With the additions, the lines of the armies south of Petersburg extended from the Appomattox River to Hatcher's Run. Lee plans to withdraw from Petersburg After the Battle of Hatcher's Run, Lee knew his army lacked the number of men needed to continue extension of his line and he realized Grant would continue to press them to do just that. On February 22, 1865, Lee advised Confederate States Secretary of War John C. Breckinridge that he expected Grant to "draw out his left, with the intent of enveloping me." He told Breckinridge and Lieutenant General James Longstreet that supplies should be collected at Burkeville, Virginia, in preparation for the army to move west. Lee wanted to move when local roads became passable as spring rains decreased and before Union reinforcements from Sheridan's cavalry from the Shenandoah Valley, recent new recruits for Grant's force, and possibly even men from Major General William T. Sherman's armies already operating in North Carolina, could arrive at Petersburg.

Johnston's force opposing Major General Sherman's Union army. After discussing the situation with Major General John B. Gordon on March 4, 1865, Lee approved Gordon's proposal to attempt to capture or break a portion of the Union lines. The expected result of a successful attack would be to threaten or damage Grant's base and supply lines, compel Grant to shorten his line from the western end and to delay his pursuit of any Confederate force's withdrawal. Then, Lee could shorten his line and send part of his army to help Johnston in North Carolina. In the alternative, Lee could move his entire army to help take on Sherman first and, if successful, turn the combined Confederate force back against Grant. On March 22, 1865, Gordon told Lee he had determined that the best place to attack would be at Fort Stedman, east of Petersburg and south of the
