HMS Firebrand was originally a mercantile schooner named Lord Lennox, which had been captured as a French prize in 1799. After her capture, she was renamed and entered into service within the Royal Navy in 1804. Prior to her acquisition by the navy, Lord Lennox had undergone a significant repair in 1799, indicating her seaworthiness and the value placed on her as a vessel. Constructed as a schooner, specific details about her dimensions, armament, or rigging are not provided in the source. Her primary role in the Royal Navy was as a fire ship, a type of vessel used to set enemy ships ablaze during naval engagements, though her service with the navy was relatively short-lived. In 1807, the navy offered her for sale at Sheerness, along with several other vessels, and she was sold back into merchant service. Following her sale, she reverted to her original name, Lord Lennox, and re-entered Lloyd's Register in 1808. Under her former name, she was registered with Whiteside as master and Hedgecock as owner. Her trade routes included London to Cadiz, and later she traded between London and Lisbon. The vessel continued her mercantile operations at least until 1815, the last year she was listed in the Register of Shipping. Overall, HMS Firebrand (originally Lord Lennox) exemplifies a versatile vessel captured and repurposed for military use during the early 19th century, although her service as a fire ship was brief. Her subsequent commercial career highlights her adaptability and the common practice of repurposing vessels between military and merchant roles during this period.
