Much is known about Britain's role in the Atlantic slave trade during the eighteenth century but few are aware of the sustained campaign against slaving conducted by the Royal Navy after the passing of the Slave Trade Abolition Act of 1807. Peter Grindal provides the definitive account of this little known yet important part of the British, European and American history. Drawing on original sources to provide a comprehensive and engaging narrative of the naval operations against slavers of all nations - in particular Portugal, Spain, the Netherlands and Brazil, he describes how illegal traders sought to evade treaty obligations, reveals the obduracy of the USA that prolonged the slave trade, and shows how, despite inadequate resources, the Royal navy's sixty-year campaign forced slavers to expend ever greater sums top conduct their business and confront the losses inflicted by capture and condemnation. A work that will transform our understanding of the Royal Navy's campaign against the Atlantic slave trade.
