Morgan surprised and captured the Federal garrison at Lebanon. With minimal time to prepare, Union Lt. Col. Charles S. Hanson (a brother of Confederate general Roger Hanson) quickly deployed his 350 - 400 men from the 20th Kentucky Infantry behind overturned wagons, hastily erected barricades, fences, and other cover. Arriving at the town, Morgan formally requested that Hanson surrender, an offer that was refused. With a huge numerical advantage, Morgan quickly pushed Hanson's advance pickets back through the town's streets. He trapped many of the Union soldiers in the Louisville and Nashville Railroad depot, but the well fortified brick building provided considerable protection. Morgan ordered nearby buildings set on fire, hoping to force Hanson to surrender. In a sharp six-hour fight, Federal troops killed Morgan's 19-year-old brother, Lt. Thomas Morgan, during the final charge. General Morgan finally captured and paroled the enemy soldiers. His men burned the offices of the Circuit Clerk and County Clerk, as well as 20 other buildings.
