The Thirteenth New Hampshire was deployed in a reserve position at the rear of the Union line. Although exposed to Confederate fire the Thirteenth was not engaged in battle. A grand infantry charge began at 4:30 A.M. with Union artillery fire to support the infantry. Poor reconnaissance concerning the difficult ground the Union traversed to attack the well-entrenched Confederates proved disastrous. The Union assault terminated by 1:00 P.M. Casualties were staggering for the Union, as in the first twenty minutes of the charge nearly ten-thousand Union infantry soldiers were killed or wounded.1
