HMS Mary Galley was a 44-gun fifth-rate frigate of the Royal Navy, constructed in 1744. Designed for wartime service during the War of the Austrian Succession, she served primarily in patrol and protection roles against France, Prussia, and Spain. The ship’s armament of 44 guns positioned her as a formidable vessel capable of engaging enemy ships and providing convoy protection. Initially commissioned under Captain Piercy Brett, command was transferred to Captain William Dandridge before her deployment, though Dandridge died in August 1745, and command then passed to Captain Robert Swanton. Under Swanton, HMS Mary Galley conducted extensive patrols along the Bristol Channel, the Downs, and into the North Sea, demonstrating her role in maritime surveillance and regional dominance. In March 1746, she underwent minor repairs at Sheerness dockyard costing nearly £1,000, reflecting routine maintenance during her active service. Following her patrol duties, the vessel was assigned to Atlantic service off West Africa and subsequently operated in the Leeward Islands from 1747 to 1748, highlighting her involvement in protecting British colonial and commercial interests during wartime. After returning to Plymouth Dockyard in 1749, she was surveyed for damage but not repaired, and remained largely abandoned in port, signaling the end of her active service life. By 1764, HMS Mary Galley was offered for sale as a simple hull with basic fittings, but no buyers emerged. Instead, she was decommissioned and repurposed as part of a breakwater, sunk in Plymouth harbor on 20 April 1764. Her service history reflects the typical lifecycle of mid-18th-century naval vessels, from active wartime deployment to post-war disposal and secondary use, illustrating the practicalities of ship management and maritime defense during that period.
