Inscribed by Pocock in pencil, 'Sir J. T. Duckworth', 'Final View' (with a sight-line indicated) and with the names and positions of the ships. This is a preparatory plan for the large oil painting (NMM BHC0571) of Sir John Thomas Duckworth's victory off San Domingo, which formed a somewhat overlooked postscript to Trafalgar in destroying French naval power in the West Indies. Duckworth's 'Superb' engages the French flagship 'Imperial' in the centre.
