HMS Dreadnought was a Royal Navy second-rate ship of the line, armed with 98 guns. Launched at Portsmouth on 13 June 1801 after 13 years on the stocks, she was notable for being the first man-of-war launched following the Act of Union 1800. Her launch was a grand spectacle, witnessed by around 10,000 spectators, with a ceremonial bottle breaking and a lavish collation for nobility and officers. Constructed over a period of more than a decade, Dreadnought was swiftly coppered immediately after her launch, with her hull being fully coppered in just six hours. Her initial command was under Captain James Vashon, and she cruised primarily in the Channel, later moving to waters off Cádiz and Menorca. Throughout her early service, she saw various commanders, including Mr. Banks, Joseph Foss Dessiou, Captain Edward Brace, Captain John Child Purvis, Robert Carthew Reynolds, George Reynolds, and Edward Rotheram, often serving under prominent admirals. In the spring of 1805, Dreadnought participated in the blockade of Toulon, which was a critical component of the Napoleonic Wars. She played a significant role at the Battle of Trafalgar on 21 October 1805, where she was the eighth ship in the lee division. During the battle, she engaged the Spanish ship San Juan Nepomuceno, running her aboard and forcing her surrender after her commander was killed. Dreadnought sustained casualties of seven killed and 26 wounded during the engagement. Post-Trafalgar, Dreadnought continued patrols, including blockades and convoy duties around Cadiz, and participated in various actions along the French coast. She served in the Channel Fleet and the Baltic until 1812, when she was taken out of active service. Later, she was repurposed as a lazaretto and hospital ship, serving at Milford on Sea and as part of the Seamen's Hospital Society until her breakup in 1857. Her legacy extended into hospital services, with her infirmary eventually evolving into the Dreadnought Hospital at Greenwich, which has continued in various forms into the present day.
