The image represents the H.M. Gun-boat ""Teaser"" (on left) approaching the slaver ""Abbot Devereux"" (on right). The slaver was captured off the coast of Whydah. An eyewitness provided an account of the capture dated August 6th, 1857, to The Illustrated London News, the source of this image. The slaver had a full cargo of slaves destined for Cuba, but instead it was conducted to Sierra Leone by the British naval force.
