The Battle of Chancellorsville was important, because it was a significant battle for the Confederates. They had an army half the size of the Unionists army and decided to divide their army, but were still successful in beating them. This was the second bloodiest battle of the Civil War (seen as one of the bloodiest wars in history). Quite a few generals were involved in the battle and the battle took place in Spotsylvania County in the state of Virgina. This was season as the "perfect battle" for the Confederate Army.
