Bunker Hill was a Massachusetts privateer sloop commissioned in 1778, notable for its active service during the American Revolutionary War. She was a relatively small vessel, with her initial capture of one vessel during her first cruise, which was possibly the 50-ton brig Mary. Under the command of Edward Rolland, she embarked on her first cruise in mid-June 1778, returning in September after capturing a vessel. Commissioned later by Commander Nicholas Ogelbe on 27 October 1778, Bunker Hill set sail from Salem with the intent to cruise off Barbados. Early in her second cruise, she captured the 100-ton schooner Delaware, sailing from Quebec to New York with a cargo of flour, shortly after leaving port. Her service was characterized by swift sailing, which drew the attention of the British Royal Navy. On 22 December 1778, Bunker Hill mistakenly entered Grand Cul De Sac Bay at Saint Lucia, believing she was rendezvousing with French forces under Count d'Estaing. The British fleet under Admiral Barrington was anchored nearby, and upon realizing her error, Bunker Hill was captured by British boats before French intervention could occur. Recognizing her speed, Barrington took her into Royal Navy service, renaming her HMS Surprize in honor of her mode of capture. She was commissioned on 25 December 1778, with Lieutenant James Brine appointed as her master and commander. Throughout her Royal Navy service, Surprize participated in notable actions, including capturing the Elizabeth in April 1779 and aiding in the surrender of Demerara and Essequibo in March 1781, alongside HMS Barbuda. She served primarily in the Caribbean, operating under several commanders, including George Day and William Miller. Her service included coppering at Antigua in August 1782, a process that enhanced her seaworthiness. The Navy paid her off in November 1782, and she was sold on 16 January 1783 for £550. It is believed that she may have been purchased by the French Navy, renamed Surprise, and eventually broken up at Rochefort in 1789. Her service record highlights her role as a swift and versatile vessel during a turbulent period of naval warfare.
