The Essex Junior was originally a French vessel that came into British hands and was repurposed as a whaling ship by Samuel Enderby & Sons. Initially registered under the name Atalanta in 1810, she was commanded by O. Gwyer and operated on routes between London and the South Seas. Built as a sloop, she was designed for long-distance whaling expeditions, with her trade primarily focused on the Peruvian coast and the Galapagos Islands. By September 1811, she was reported off the coast of Peru with a cargo of approximately 1,000 barrels of sperm oil, indicating her active participation in the lucrative whaling industry. In 1812, she departed St. Helena for home, returning to London in July of that year. Captain Obed Wyer (or Gwyer) undertook another voyage to the Galapagos in October 1812. Her service took a dramatic turn in April 1813, when the American frigate USS Essex captured her off the Galapagos Islands and renamed her Essex Junior. The Americans outfitted her as a tender under Commander John Downes, mounting a total of six guns (though her hull was pierced for twenty) with additional armament including 6-pounder guns and 18-pounder carronades, and crewed her with around 60 officers and men. Essex Junior accompanied Essex to Nuka Hiva in the Marquesas for repairs and later returned with her to the South American coast, reaching Chile in early 1814. The vessel was detained at Valparaíso by the British, who kept her trapped in the harbor for six weeks before a naval engagement on 28 March 1814 resulted in her capture. During the battle, British ships Phoebe and Cherub inflicted significant casualties, with Essex reportedly suffering higher losses. After her capture, Essex Junior was used as a cartel to transport prisoners to New York. However, her status was complicated when the British detained her outside New York; she was eventually released after escaping shoreward, despite efforts by British forts to stop her. Upon her arrival in New York in July 1814, Essex Junior was seized by U.S. authorities, condemned, and sold for $25,000. Her service history highlights her transition from a whaler to a prize vessel involved in the naval conflicts of the War of 1812, reflecting her maritime significance in both commercial and military contexts.
