His 2nd Medal of Honor Citation reads:
Serving with the 15th Company of Marines on 22 October 1915, G/Sgt. Daly was one of the company to leave Fort Liberte, Haiti, for a 6-day reconnaissance. After dark on the evening of 24 October, while crossing the river in a deep ravine, the detachment was suddenly fired upon from 3 sides by about 400 Cacos concealed in bushes about 100 yards from the fort. The marine detachment fought its way forward to a good position, which it maintained during the night, although subjected to a continuous fire from the Cacos. At daybreak the marines, in 3 squads, advanced in 3 different directions, surprising and scattering the Cacos in all directions. G/Sgt. Daly fought with exceptional gallantry against heavy odds throughout this action.
