Eight Hopi code talkers were in the 81st Division. Although Frank Chapella, Franklin Shupla and Warren Koopyaquaptewa were all from the village of Tewa, they were both Tewa and Hopi and so spoke both of these tribes’ languages. Frank Chapella’s wife, Elidia Chapella, and his son, Marshall Shupla, recall how these three individuals spoke to one another in Tewa (their matrilineal classification through their mothers) and in Hopi with the other five members of their unit.
