This article explores the Detached Papers of the Company of Merchants Trading to Africa, an underused sub-series within The National Archives’ T 70 collection. These records offer a unique and detailed insight into the British administration of West African forts, and the lives of enslaved people forced to work in these fortifications. While the Royal African Company has been the subject of extensive scholarship, the Company of Merchants – its successor – remains understudied. Through letters, minute books, fort lists, and financial records, the Detached Papers, recently catalogued at item level for the first time, provide a critical and untapped source on the eighteenth-century Atlantic world, revealing overlooked narratives of local relationships, familial networks, and the operational structures that underpinned the transatlantic trade in enslaved Africans. This article focuses on three key areas to exemplify the importance of these records for future research: the cultural and political life of the Fante; the networks and influence of Company Governor Richard Miles; and the identities and experiences of enslaved people in British-controlled forts. By engaging with the fragmentary nature of these records, the article interrogates archival silences to surface the submerged histories of exploitation, agency, and survival within the archives of enslavement.
