 None of the listed sources give an accurate accounting of the ships in Rodney 's fleet at the time of the action . Robert Beatson lists the composition of the fleet at its departure from England , and notes which ships separated to go to the West Indies , as well as those detached to return the prizes captured on 8 January to England . He does not list two ships ( Dublin and Shrewsbury , identified in despatches reprinted by Syrett ) that were separated from the fleet on 13 January . Furthermore , HMS Prince William is sometimes misunderstood to have been part of the prize escort back to England , but she was present at Gibraltar after the action . Beatson also fails to list a number of frigates , including HMS Apollo , which played a key role in the capture of the Monarca .
