On July 2, 1863, the 12th New Hampshire was heavily engaged north of the Klingel Farm, facing attack by Wilcox's Alabama brigade. The regiment had 224 men on the field that day, of whom 26 were killed and 73 were wounded (an additional six men would die of their wounds). Captain John F. Langley (Company F) was in command, and was wounded when the regiment was ordered to withdraw. Lieutenant William H. H. Fernel (Company I) took command and was able to rescue some 50 Union soldiers who were captured during the withdrawal. The following day, only 50 men were fit for duty under the command of Captain Thomas E. Barker (Company B). Placed near the center of the Union line, they helped repulse Pickett's charge.
The regiment lost a total of 320 men during service; 11 officers and 170 enlisted men killed or mortally wounded, 1 officer and 138 enlisted men died of disease.
