On December 13, the "grand division" of Maj. Gen. William B. Franklin was able to pierce the first defensive line of Confederate Lieutenant General Stonewall Jackson to the south, but was finally repulsed. Burnside ordered the grand divisions of Maj. Gens. Edwin V. Sumner and Joseph Hooker to make multiple frontal assaults against Lt. Gen. James Longstreet's position on Marye's Heights, all of which were repulsed with heavy losses.
