HMS Leander was a 50-gun, spar-decked frigate of the Royal Navy, classified as a fourth-rate vessel. Constructed rapidly from pitch pine and softwood, she was ordered in May 1813 from Wigram, Wells & Green, laid down in June 1813, and launched on 10 November 1813, just under five months later. Her design was by William Rule, and her construction aimed at quickly entering service during the ongoing conflicts of the Napoleonic Wars and the War of 1812. The ship featured a distinctive spar-deck configuration, with a continuous row of guns on the upper deck, including thirty 24-pounder guns on her main deck and twenty-six 42-pounder carronades on her spar deck, along with four 24-pounders on her forecastle. During her service, her armament was slightly modified, replacing two carronades with two additional 24-pounders. HMS Leander was known for her speed, exceeding 13 knots, although she initially suffered from heavy and violent movements, attributed to poor stowage, which was later rectified. She was designed to counter the American heavy frigates, such as USS Constitution, and operated extensively in North American waters. Under Captain George Collier, she captured the USS Rattlesnake in June 1814 and participated in pursuits of the USS Constitution, although the American ship ultimately evaded capture. She also recaptured the British merchant vessel John in January 1815. After the War of 1812, Leander was refitted for service as a flagship, notably in the Mediterranean during the Second Barbary War, where she participated in the bombardment of Algiers in 1816, firing over 3,600 rounds and sustaining casualties of 17 killed and 118 wounded. She served as the flagship of Rear-Admiral Sir David Milne on the North American Station in 1817, based at Halifax, and later in the East Indies as flagship for Rear-Admiral Sir Henry Blackwood. Her later years were spent as a receiving ship at Portsmouth, where she remained until she was broken up in 1830. Leander's service reflects her significance as a large, powerful frigate designed for rapid response and flagship duties during a transformative period of naval history.
