HMS Defence was a 74-gun third-rate ship of the line of the Royal Navy, launched on 25 April 1815 at Chatham Dockyard. Ordered on 23 March 1809, her construction began in May 1812, reflecting a typical design for a ship of her class during the period. As a third-rate vessel, she was part of the core fleet of the Royal Navy, designed to combine firepower and maneuverability, with a substantial armament of 74 guns. Her service history includes her commissioning shortly after the Napoleonic Wars, during a period of transition in naval warfare. Although specific operational details are limited, her designation as a ship of the line indicates she was built for frontline engagement, capable of forming the backbone of fleet actions. In 1849, HMS Defence was repurposed to serve as a prison ship, a common practice for aging warships no longer fit for combat but still seaworthy. This conversion extended her service life, allowing her to support naval operations in a non-combatant role. A notable event in her later history occurred on 14 July 1857, when she was badly damaged by an accidental fire at Woolwich. The fire was likely caused by spontaneous combustion in a recently delivered load of coal, a hazard known to affect wooden ships and their cargo. The damage was severe enough that the ship was deliberately scuttled to extinguish the fire. Following this incident, HMS Defence was broken up later that same year, marking the end of her existence. Overall, HMS Defence exemplifies the transition of naval assets from active line-of-battle ships to auxiliary roles, and her history reflects the broader evolution of the Royal Navy during the early to mid-19th century.
