The Thirteenth New Hampshire was hard at work digging ditches and earthworks in preparation for a siege by Confederate forces under General James Longstreet. Today the Ninth Corps formed a line of battle along the Nansemond River, nearly three miles south of Suffolk. The Confederates were entrenched in a large force near the Petersburg Railroad to protect their supply lines. The Thirteenth New Hampshire spent the evening on picket duty and the regiment was at arms during the night.1
