We are remembering the Battle of Richmond, Kentucky on August 29 - 30, 1862. It was one of the most decisive and complete Confederate victories of the war. Kirby Smith accomplished a tactical victory by picking the ideal battle location against a larger, inexperienced army.
Both sides were aware that over 2,000 raw recruits had joined the Union army in Lexington a few days earlier. Out of town, General "Bull" Nelson ordered an immediate retreat when informed of the approaching Confederate forces. Despite being 2:30 AM, Nelson jumped out of bed to rush to the field. He rallied the troops but was unable to prevent the rout. Nelson was barely able to escape with some of his men.
The victory opened the way north towards Lexington and Frankfort for the Confederates.
