Rage Of Battle’ Forever Haunted Some Veterans. In 1862, Owen Flaherty left his wife and son in Terre Haute, Ind., and joined the 125th Illinois Infantry. He was, by all accounts, a quiet and easygoing man, well-liked and quick to share a laugh and a drink with his comrades. Until the Battle of Stones River, that is. After that horrendous four-day battle, fought from December 31, 1862, to January 3, 1863, Flaherty reportedly grew increasingly morose, sinking into what one soldier called a “deep study all the time.” He had difficulty sleeping, and was constantly troubled by nightmares. Owen sank further into despair the next year and a half, until a ground-shaking artillery barrage at Resaca, Ga., in May 1864 sent him irrevocably over the edge. He wandered off at all hours, ate and slept alone, and was quick to anger. Once, while on picket duty, he ran into camp shouting that the enemy was coming, when no hostile force was anywhere near.
