This pamphlet denounces the continued involvement of French ships and capital in the slave trade, and aims to rouse national indignation in France. It includes an extract from a pamphlet by Thomas Clarkson distributed among delegates at the Congress of Aix-la-Chapelle in 1818, describing the renewed French slave trade, and another extract from Clarkson's The Cries of Africa; letters detailing the arrival of slave ships in Guadeloupe taken from the abstract of African Institution reports, entitled 'Foreign Slave Trade' (1821); letters from a French slave trader which had been found on a ship in the Indian Ocean; and a report on continued slave trading off the coast of West Africa, written by the Governor of Sierra Leone, including a table of names of French slave ships.
