The French brig Milan, constructed at Saint Malo and designed by François Pestel, was a vessel of notable design and service during the early 19th century. Built from plans that had previously served for ships like Curieux and Palinure, Milan was a brig of approximately 327 tons (bm) according to her British specifications. She was commissioned in the French Navy on 20 January 1808 under Lieutenant-Commander Jacques de Saint-Cricq. Milan measured roughly 140 tons (bm) and featured the typical brig rigging of her era. Her initial service began with a voyage from Saint Malo in March 1808, carrying 67 men of the 86th Line Infantry Regiment to Cayenne. During this expedition, she captured the British merchant Neptune near Cape Ortegal and scuttled her by fire. Milan’s operations included cruising off the French coast and in the Caribbean, notably in Cayenne and Gouadeloupe, demonstrating her role in France’s naval efforts during the Napoleonic Wars. Her service was marked by several engagements and captures, including an inconclusive encounter with a British frigate, and her eventual fate was sealed when she was captured by HMS Surveillante and HMS Seine off Ile de Ré in October 1808 while transporting soldiers. The British then commissioned her into Royal Navy service as HMS Achates. As Achates, she served primarily in the Channel under Commander John Davies from 1810, capturing or detaining numerous vessels including American ships and British merchantmen, reflecting her active role in maritime warfare and blockade operations. Achates participated in notable captures, such as the American brig Mary Ann and the brig Spitfire, and was involved in recapturing vessels like Oceano and Amity. She also encountered and engaged with French vessels, notably capturing the damaged French frigate Clorinde in 1814, which she towed into Portsmouth. Her operational history includes salvage operations, detainments, and engagements during the Napoleonic and War of 1812 periods. Decommissioned and laid up in 1815, Achates was sold in 1818 for £1,100. Her design, captured from the French, and her active service record highlight her importance as a versatile and active vessel during a turbulent period of maritime conflict.
