HMS Defender was originally a French privateer lugger named Bon Marcel (also recorded as Beau Marseilles), which the Royal Navy captured in 1809. At the time of her capture on 10 December 1809 by the Royalist, she was a remarkably young vessel, only three months old, armed with 14 guns, and manned by a crew of 60. Commander John Maxwell of the Royalist described her as "a very beautiful vessel" and noted her exceptional speed, calling her "one of the fastest sailers out of Boulogne." After her capture, the Royal Navy took Bon Marcel into service as HMS Defender. She underwent fitting at Sheerness from 15 February to 16 March 1811 to prepare her for active service. In January 1811, Lieutenant Moses Cannadey was commissioned to command her, and she served primarily in the waters around the English coast, known as Home Waters. Her service record includes the notable event of capturing the vessel Hope on 24 June 1813. Additionally, she shared prize money for the capture of Hoop with the ship Decoy, indicating her involvement in naval operations against enemy vessels. HMS Defender's operational career was relatively brief, lasting just over three years, during which she contributed to British efforts in maritime patrolling and escort duties. In August 1814, she was offered for sale and was subsequently sold at Chatham for £280 on 1 September 1814. Her sale marked the end of her service in the Royal Navy, and she is remembered as a swift and agile vessel, originally a privateer, that was pressed into naval service during the tumultuous years of the Napoleonic Wars.
