Sheridan and Custer, having defeated Early, returned to the main Union Army lines at the Siege of Petersburg, where they spent the winter. In April 1865 the Confederate lines finally broke, and Robert E. Lee began his retreat to Appomattox Court House, pursued by the Union cavalry. Custer distinguished himself by his actions at Waynesboro, Dinwiddie Court House, and Five Forks. His division blocked Lee's retreat on its final day and received the first flag of truce from the Confederate force. After a truce was arranged Custer was escorted through the lines to meet Longstreet, who described Custer as having flaxen locks flowing over his shoulders, and Custer said “in the name of General Sheridan I demand the unconditional surrender of this army.” Longstreet replied that he was not in command of the army, but if he was he would not deal with messages from Sheridan. Custer responded it would be a pity to have more blood upon the field, to which Longstreet suggested the truce be respected, and then added “General Lee has gone to meet General Grant, and it is for them to determine the future of the armies.” Custer was present at the surrender at Appomattox Court House and the table upon which the surrender was signed was presented to him as a gift for his wife by Sheridan, who included a note to her praising Custer's gallantry. She treasured the gift of the historical table, which is now in the Smithsonian Institution.
