HMS Conqueror a 74-gun 3rd rate ship of the line which fought at Trafalgar under the command of Captain Israel Pellew, brother of Sir Edward Pellew. Pellew's captain of marines took the surrender of the overall commander of the French-Spanish fleet, Admiral Villeneuve's sword, aboard the French ship Bucentaure (80). However, he was not able to deliver the sword back to the Conqueror as she had passed on to engage another ship and it was received by the captain of Mars.
