The chapters in this volume move from the Indian to the Atlantic Ocean. Clifford Pereira writes that in the nineteenth century, the Indian Ocean witnessed another diasporic event in the return of African captives to their homelands. Royal Navy squadrons rescued Africans from the East African coast from slave ships operating in the Indian Ocean. With the supposed objective of protecting them from slave traders, these individuals were placed in Christian missionary orphanages in the Indian city of Mumbai (then Bombay).  
Pereira traces the trajectories of individuals who returned from Bombay to Rabai and Frere Town in Kenya, such as Seedi Mubarak Mumbai (c.18201885), known as 'Seedi Bombay'. He accompanied European explorers and is considered one of the most travelled Africans of his day, easily exceeding any European 'explorer' in Africa. For the author, the young people who were rescued had 'African origin' in common and developed a sense of community without ethnic barriers and simply imbued with the idea of freedom.  
In her chapter, Suzanne Schwarz analyses how the British colony of Sierra Leone emerged as an important site in the global diaspora of Africans uprooted and displaced by the Atlantic slave trade. Following the transfer of the settlement to British Crown control in 1808, the multi-ethnic composition  
of the settlement was increased markedly through the forced relocation to Freetown of tens of thousands of Africans released from slave ships on the West African coast by Royal Navy patrols. Sierra Leone developed as an early and important site of experimentation in Protestant missions, which had an impact beyond the geographical limits of the small colony. Although earlier historical writing has placed emphasis on the work of European missionaries, this chapter emphasizes how an outstanding characteristic of activity in Sierra Leone was the extensive and independent roles of people of African origin and descent.
