HMS Defiance was a notable third-rate ship of the line in the Royal Navy, initially launched in 1675 from Chatham Dockyard, built by Phineas Pett II. She was armed with 64 guns, reflecting the typical firepower of a third-rate vessel of her time, and served as a key component of England's naval forces during the late 17th and early 18th centuries. The ship underwent a significant rebuild at Woolwich Dockyard in 1695, during which her armament remained at 64 guns. She was actively involved in naval operations, including participation in the squadron under Vice-Admiral John Benbow in August 1702. During this engagement against the French squadron commanded by Admiral Jean du Casse, HMS Defiance, under Captain Richard Kirkby, notably refused to engage the enemy after only a few broadsides, choosing to bear away from the fight. This act of apparent cowardice led to Kirkby's court-martial and subsequent execution by firing squad. In 1707, HMS Defiance was rebuilt for a second time at Deptford Dockyard, emerging as a 66-gun third-rate ship, slightly increasing her firepower. Her classification changed in 1716 when she was reduced to a fourth-rate vessel, indicating a reduction in her size and armament. The ship's later service included command by Captain John Trevor starting in 1739, and she continued in service until she was hulled in 1743, marking her transition from an active warship to a stationary support vessel. Ultimately, HMS Defiance was broken up in 1749, ending her nearly 75-year-long service life. Her history reflects the evolving design and strategic roles of ships of the line during her era, as well as the importance placed on discipline and combat performance in the Royal Navy.
