HMS Diligent was a 12-gun brig-sloop of the Royal Navy, purchased in 1777 for £420 4s 0d. Constructed as a small, maneuverable vessel, she served during the American Revolutionary War, primarily operating along the American coast and in Chesapeake Bay. Her dimensions and specific construction details are not provided in the source, but as a brig-sloop of her class, she would have been a relatively small, two-masted vessel designed for versatility and speed. Commissioned under Lieutenant Thomas Farnham in August 1777, Diligent quickly became involved in various patrols, engagements, and cutting-out missions. She engaged American vessels near Long Island, firing on schooners and attempting to cut off whaleboats, demonstrating her role in harrying American coastal activities. In October 1778, she helped capture the brig Recovery sailing from Portsmouth to Charleston. Under the command of Lieutenant Thomas Macnamara Russell in February 1779, Diligent captured four small vessels during a cruise off Chesapeake Bay, including the notable prize Lady Washington, which was armed with 16 guns and fought until surrendering. She also pursued enemy brigs escorting a convoy, leading to the capture of one vessel carrying flour and tobacco, contributing to her tally of eight ships taken over five weeks. In May 1779, under Lieutenant Thomas Wabeoff, Diligent engaged in a brief but fierce battle with the Continental Navy’s sloop Providence, resulting in the loss of 11 crew members and her subsequent sinking to prevent capture. Her crew ran her ashore and burnt her at Penobscot Bay on 14 August 1779, during the failed Penobscot Expedition, marking her end. Her service record highlights her active participation in blockade, patrol, and combat operations during the American Revolutionary War, reflecting her significance as a versatile and effective vessel in the Royal Navy’s coastal efforts, and later as part of the Continental Navy’s brief fleet before her destruction.
