As Lee's army attempted to escape to Farmville, Longstreet was engaged at Sailor's Creek on April 6. The Confederates were unable to reach the town, but with the assistance of troops under Anderson and Ewell, managed to prevent federal troops from blocking the army's last path of escape. The overall battle ended in disaster, with nearly 7,000 of the 10,000 Confederate troops engaged killed, wounded, or captured. By April 7, Lee's army had been reduced from nearly 40,000 men on March 31 to 25,000. A group of Confederate officers including William N. Pendleton concluded that the time had come to ask Lee to open negotiations for the army's surrender. Pendleton approached Longstreet and asked him to intercede with Lee, but he refused, saying, "If General Lee doesn't know when to surrender until I tell him, he will never know." Nevertheless, Pendleton approached Lee, who was in communication with Grant on the subject of Confederate surrender, but refused to surrender the army. Lee held his last conference of war on the night of April 8. It was decided that at daybreak, Longstreet would hold the Union troops back while John B. Gordon would lead an escape towards Lynchburg, and then cover his retreat. At the Battle of Appomattox Court House that morning, Longstreet was heavily engaged with the Union II Corps under Andrew A. Humphreys. Gordon's troops were surrounded, and he requested reinforcements which Longstreet could not furnish. Lee was left with no alternative but to meet General Grant to discuss surrender.
