Although little is known about PFC Delgado's World War II service, the web address listed below provides a history of the 4th General Hospital Unit. At the bottom of this webpage there is an incomplete roster, taken from the 1945 published Unit History of the 4th General Hospital which is limited to mostly surnames only. However, there is a Delgado included in the roster of Enlisted Men. https://www.med-dept.com/unit-histories/4th-general-hospital/
