What happened in the civil war december 13 1863

The Battle of Fredericksburg was fought December 11–15, 1862, in and around Fredericksburg, Virginia in the Eastern Theater of the American Civil War. The combat, between the Union Army of the Potomac commanded by Major General Ambrose Burnside and the Confederate Army of Northern Virginia under General Robert E. Lee, was part of the Union Army's futile frontal attacks on December 13 against entrenched Confederate defenders on the heights behind the city. It is remembered as one of the most one-sided battles of the war, with Union casualties more than three times as heavy as those suffered by the Confederates. A visitor to the battlefield described the battle to U.S. President Abraham Lincoln as a "butchery."
