The image represents the H.M.S. ""Rifleman"" (right) pursuing the slaver ""Esmeralda"" (left). An account in The Illustrated London News, the source of this image, describes the attempt of the British ""Rifleman"" to intercept the ""Esmeralda"" off the Brazilian coast. The slaver, however, escaped and landed slaves on the coast of Rio de Janeiro. The image is reproduced courtesy of the Manuscript, Archives and Rare Book Library, Emory University.
