HMS Defiance was a 64-gun third-rate ship of the line of the English Royal Navy, constructed as part of the navy's 1664 building program. Launched on 27 March 1666 at William Castle's private shipyard in Deptford, her construction marked a significant addition to England’s naval power during the period. The ship's design would have been typical of a third-rate vessel of her time, equipped with a substantial armament of 64 guns, suitable for line-of-battle tactics. Commissioned under Sir Robert Holmes, HMS Defiance quickly became active in major naval engagements, notably participating in the Four Days Battle from 1 to 4 June 1666, a pivotal conflict during the Second Anglo-Dutch War. Throughout her brief service life, command of the vessel changed hands multiple times: after Holmes, Captain William Flawes briefly took command, followed by Rear-Admiral Sir John Kempthorne in July 1666, and later Sir John Harman in 1667, with Holmes resuming command in September of that year. These changes reflect the ship’s prominent role in the Royal Navy's strategic operations during a time of intense naval warfare. Tragically, HMS Defiance was destroyed by fire at Chatham on 6 December 1668, just over two years after her launch. The loss was attributed to neglect by the ship’s gunner, who was accused of causing the fire by trusting a girl to carry fire into his cabin. Samuel Pepys, the renowned diarist, recorded this incident in his diary, noting the circumstances surrounding the ship’s destruction and highlighting the negligence that led to her loss. The destruction of HMS Defiance marked a sudden end to her service, but her involvement in the critical naval battles of the era underscores her maritime significance during the early years of the Royal Navy’s development.
