While Meade was proclaimed the "hero of Gettysburg", President Lincoln wasn't satisfied. He had expected Meade to follow and destroy Lee's army, which could have ended the war. Meade offered Lincoln his resignation but Lincoln refused to accept it. On July 7, 1863, Meade was promoted to brigadier general in the regular army. Both the battles of Bristoe Station and Mine Run were undecisive for the Union army under Meade. In the spring of 1864, Meade again offered his resignation when General Ulysses S. Grant became general-in-chief of all Union forces and made his headquarters with the Army of the Potomac. While Meade remained in command, nearly all command decisions were made by Grant. This continued through the Siege of Petersburg after which Meade was promoted to major general. A week later, when Lee surrendered his army to Grant at Appomattox Court House, Meade was not present.
