Historians of Asante contributed their research findings to a scholarly archive known as “The Asante Collective Biography Project.” In 1979 historian Larry Yarak, whose work focused on Elmina, shared information on “Dating Asantehene Osei Kwado’s Campaign against the Banna” based on Dutch records. The campaign occurred in the dry season of 1773-74 and resulted in many war captives being traded to the Dutch at Elmina as described in this document. To cite: Yarak, Larry. 1979.
