La Forges' model of the Victory.
The HMS Victory is an ancient Earth sailing vessel and one of the most famous ships in British naval history. She served as the flagship for Admiral Horatio Nelson at the Battle of Trafalgar in 1805. Nelson himself was killed in the battle.
In 2365, Geordi La Forge was preparing to give a model of Victory to the captain of the starship USS Victory. The model was slightly damaged as a result of Moriarty's tampering with the holodeck. (TNG: "Elementary, Dear Data")
In 2366, Captain Picard remarked to Guinan that Nelson toured Victory shortly before Trafalgar while Picard himself debated whether or not to engage a Borg cube. (TNG: "The Best of Both Worlds, Part I")
