Which of the serious defeats for the Union came first in the American Civil War: the Battle of Chickamauga or the Battle of Fredericksburg?
Battle of Fredericksburg The Battle of Fredericksburg was fought December 11–15, 1862, in and around Fredericksburg, Virginia, between General Robert E. Lee's Confederate Army of Northern Virginia and the Union Army of the Potomac, commanded by Major General Ambrose Burnside, as part of the American Civil War. The Union Army's futile frontal attacks on December 13 against entrenched Confederate defenders on the heights behind the city are 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."
Battle of Wilmington The Battle of Wilmington was fought February 11–22, 1865, during the American Civil War, mostly outside the city of Wilmington, North Carolina. The Union victory in January in the Second Battle of Fort Fisher meant that Wilmington, 30 miles upriver, could no longer be used by the Confederacy as a port. It fell to Union troops after they overcame Confederate defenses along the Cape Fear River south of the city. The Confederate General Braxton Bragg burned stores of tobacco and cotton, among other supplies and equipment, before leaving the city, to prevent the Union from seizing them.
