Would you be willing to share your ancestor's name and details/sources regarding his wounds? There are not many who were struck both by small-arms and artillery during the battle. My list of casualties from the 19th Maine (July 2 only) where the type of wound is described:
Adams, John B., Pvt, C/19 ME, wounded, minie balls in abdomen, right leg, and left leg, the last received while crawling off the field on his hands and knees.
Lowe, Charles M., Pvt, K/19 ME, mortally wounded, gunshot groin, head and arm, died July 12.
Shea, Samuel B., K/19 ME, mortally wounded, minie ball left breast, died July 9.
