HMS Cornwallis was a 54-gun fourth-rate ship of the line in the Royal Navy, originally built as the Marquis Cornwallis for the Honourable East India Company. Constructed between 1800 and 1801 in Bombay by Jemsatjee Bomanjee using teak, she was designed as a spar-decked frigate intended for long-range convoy escort duties. Her dimensions and specific armament details are not provided, but as a fourth-rate with 54 guns, she would have been a sizable and versatile vessel of her time. Initially, she served in the Far East, undertaking voyages to Britain, Australia, and the Pacific Coast of South America, under command of Captain Thomas Hardie in 1802. After a series of missions, including diplomatic interventions and convoy duties, she was purchased by Admiral Sir Edward Pellew in 1805 for £68,630, soon after her return from a voyage to Britain. Under Commander Charles James Johnston from 1806, Cornwallis participated in blockade operations off Île Bonaparte (Mauritius) and engaged in actions against French and Dutch forces in the Indian and South Pacific theatres. Notably, she attempted to cut out French vessels at Saint Paul's Bay in 1806, and in 1807, cruised along the South American coast, capturing and destroying numerous small vessels, including the ship Atlantic and the brig Rosalía. Her cruise extended to the Pacific, where she navigated with remarkable skill after wrecking the Rosalía at Minerva Reefs. Her exploits during this period are commemorated in the naming of Johnston Atoll. Throughout her service, Cornwallis engaged in various combat operations, including attacks on Dutch forts in the Celebes and Amboyna in 1810, capturing multiple Dutch vessels. She was renamed HMS Akbar in February 1811, freeing the name for a new ship. As Akbar, she participated in the capture of Java in 1811 and served in different capacities, including as a store ship and troopship. She also recaptured vessels such as Indian Lass in 1814 and served as flagship on the Bermuda station in 1815. Decommissioned and laid up at Portsmouth in 1816, she subsequently served in stationary roles as a quarantine and training ship before being sold for breaking up in 1862. Her career highlights her versatility and active engagement in key colonial and naval campaigns of the early 19th century, marking her as a significant vessel in British maritime history.
