On that day, at Binalonan on the island of Luzon in the Philippines, he exposed himself to enemy fire in order to aid two wounded soldiers.

Technician Parrish's official Medal of Honor citation reads: He was medical aid man with Company C during the fighting in Binalonan, Luzon, Philippine Islands.

In the early hours of the 24th, his company, crossing an open field near San Manuel, encountered intense enemy fire and was ordered to withdraw to the cover of a ditch.

Without hesitation he left the ditch, crawled forward under enemy fire, and in 2 successive trips brought both men to safety.

He next administered aid to 12 casualties in the same field, crossing and re-crossing the open area raked by hostile fire.
