USS Porpoise (1836)

USS Porpoise (1836) was a brig of the United States Navy and the second ship to bear the name. Launched from the Boston Navy Yard in 1836, she served as a survey vessel and later on anti-piracy patrols. The ship is best known for her participation in the United States Exploring Expedition under Charles Wilkes and for her mysterious disappearance in the Pacific Ocean in 1843.

Construction and commissioning

The vessel was constructed at the Boston Navy Yard in Massachusetts, a key naval facility during the early 19th century. She was launched on 31 May 1836, a period of significant naval expansion following the War of 1812. As a brig, she was a two-masted sailing ship, designed for both speed and versatility, making her suitable for a variety of missions from coastal survey to deep-sea exploration. Her armament consisted of two long 9-pounder guns and ten shorter-range 24-pounder carronades, a typical configuration for a vessel of her class intended for patrol duties. Following her outfitting, she was placed into commission later in 1836 under the command of a United States Navy officer, joining the growing Home Squadron.

Service history

The early career of the brig involved routine patrol and survey duties along the Atlantic Coast of the United States. Her most significant assignment began in 1838 when she was assigned to the historic United States Exploring Expedition, commanded by Lieutenant Charles Wilkes. This ambitious multi-year voyage aimed to survey the Pacific Ocean and the Southern Ocean, and the vessel served as one of the expedition's primary survey ships. During this mission, she cruised throughout the vast Pacific, visiting locations such as the Fiji Islands, Samoa, and the Oregon Country, contributing to the expedition's extensive hydrographic and scientific work. Following the return of the expedition to New York City in 1842, the ship was reassigned to anti-piracy and anti-slavery patrols in the West Indies and the Gulf of Mexico, operating as part of the African Slave Trade Patrol.

Fate

In 1843, after departing from New York Navy Yard for a deployment to the Pacific Squadron, the brig vanished without a trace. She was last reported seen in the vicinity of the Society Islands in the central Pacific Ocean. An extensive search was conducted by other vessels of the United States Navy, including ships from the Pacific Squadron, but no wreckage or definitive evidence of her fate was ever discovered. The Navy officially declared her lost with all hands, a crew of approximately 80 men under the command of Lieutenant Alonzo B. Davis. Her disappearance remains one of the enduring maritime mysteries of the antebellum United States Navy, with theories ranging from catastrophic structural failure to foundering in a severe storm or typhoon.

Legacy

Despite her tragic end, the ship left a notable legacy through her contributions to American science and naval history. The charts and scientific data collected during the United States Exploring Expedition, to which she was integral, were published in the influential Narrative of the United States Exploring Expedition and informed American commercial and strategic interests in the Pacific Ocean for decades. The expedition's collections also formed the core of the Smithsonian Institution. The name Porpoise was subsequently carried by several other U.S. naval vessels, including submarines during World War II. Her story is often cited in historical studies of 19th-century naval exploration and the hazards of maritime service during the age of sail.
