Despite the successful morning attack, access to an open escape route, and to the amazement of Floyd and Buckner, Pillow ordered his men back to their trenches by 1:30 p.m. Buckner confronted Pillow, and Floyd intended to countermand the order, but Pillow argued that his men needed to regroup and resupply before evacuating the fort. Pillow won the argument. Floyd also believed that C. F. Smith's division was being heavily reinforced, so the entire Confederate force was ordered back inside the lines of Fort Donelson, giving up the ground they gained earlier that day.
