Admiral Sir Eliab Harvey was an eccentric and hot-tempered officer of the Royal Navy during the French Revolutionary and the Napoleonic Wars who was as distinguished for his gambling and dueling as for his military record. Although Harvey was a significant naval figure for over twenty years, his martial reputation was largely based on his experiences at the Battle of Trafalgar, when he took his ship HMS Temeraire into the thick of the action. Harvey used Temeraire to force the surrender of two French ships of the line and later created his family motto from the names of his opponents in the engagement; "Redoutable et Fougueux".

HMS Santa Margarita was a 36-gun fifth-rate frigate of the Royal Navy. She had been built for service with the Spanish Navy, but was captured after five years in service, eventually spending nearly 60 years with the British.
