Thomas ap Catesby Jones was born on 24 April 1790 in Westmoreland County, Virginia, to Catesby and Lettice Jones. The Jones family had originated in Wales and the middle name "ap Catesby" was a gesture to the patronymicsurnames traditionally used in Wales; Thomas ap Catesby in Welsh means "Thomas, son of Catesby". Jones' father died on 23 September 1801 leaving the family destitute. Jones and his older brother, Roger were taken in by an uncle, Meriwether Jones of Richmond, Virginia. His mother died in December 1804 after a long illness leaving Jones an orphan at age 14. His uncle provided for his and his brother's education at Richmond Academy until the expense of private school became a burden. They studied with a private tutor after leaving the school. Roger Jones would later become Adjutant General of the U.S. Army.
Jones was appointed a midshipman in the U.S. Navy on 22 November 1805 at the age of fifteen, but owing to a lack of openings for midshipmen he was not ordered to active duty. He was furloughed home and advised to study geography, navigation, and surveying so that his chances of getting an active assignment would improve. After the Chesapeake–Leopard Affair, the Navy mobilized its gunboats and Jones was ordered to report to Norfolk, Virginia, where he was assigned to gunboat No. 10, reporting the first week of August 1807. Thomas Jones received honors for bravery at the Battle of Lake Borgne, Louisiana, delaying the British before the Battle of New Orleans.
Between wars
In 1826, Commodore Jones while in command of the veteran sloop-of-warPeacock, signed treaties with the Kingdom of Tahiti and Hawaiian Kingdom On September 6, 1826, Jones signed a treaty with Queen regentPōmare Vahine on the behalf of the infant Pōmare III and other chiefs of Tahiti. On December 23, 1826, Jones signed a treaty with Queen regent Kaʻahumanu and other chiefs of Hawaii on behalf of the young Kamehameha III. In 1827, Peacock was severely damaged in an attack by a whale. Upon return to New York in October 1827, she was decommissioned and broken up in 1828. She was rebuilt as Peacock, to serve as an exploration ship of the United States Exploring Expedition. Jones was to have commanded the expedition, but lack of funding delayed the expedition until 1838, by which time he had resigned the appointment. In May 1836, an act of Congress authorized the President to establish the five year United States Exploring Expedition "to the Pacific Ocean and South Seas", the first extra-continental American scientific exploration. Jones was appointed Commander of the Expedition. However, delays in Expedition departure dates, and various other disagreements, led to Jones declining the position in December 1837. The position was subsequently offered to Charles Wilkes. From 1841 to 1844, Jones commanded the United States Pacific Squadron, and again from 1848 to 1850. In 1842, four years before the start of the Mexican–American War, Jones mistakenly thought that war had begun; he seized the California port of Monterey and held it for one day before returning control to Mexico. Hearing that British Captain Lord George Paulet had seized the Hawaiian Kingdom, he sailed there and arrived July 22, 1843. The king was restored July 31, and Jones tried to hasten peace by hosting all parties to dinner aboard his ship. In 1843, Jones returned a young deserter, Herman Melville, to the United States from the Sandwich Islands, as the Hawaiian Islands were then known. Later, Melville modeled "Commodore J—" in Moby-Dick, and the Commodore in White-Jacket after Jones. In 1827 Peacock under Jones's command had been severely damaged in an attack by a whale, which Melville took to have been a sperm whale. Moby-Dick may have partially inspired the story told of Jones in Chapter 45 "The Affidavit". By early 1844 Alexander Dallas had replaced Jones as Pacific commander.
Mexican War
In 1848, Jones arrived in Mazatlán just at the end of the Mexican–American War, maintaining order until he could transport those who had aided the United States in that war to Monterey.
Later career
For the next two years, during the chaotic Gold Rush days, Jones provided a U.S. Navy presence in the San Francisco area while the United States debated what to do with the newly acquired California Territory. In 1850, in a politically charged court-martial shortly after White-Jacket was published, Jones was found guilty on three counts mostly related to "oppression" of junior officers and relieved of command for two-and-a-half years. In 1853, President Millard Fillmore reinstated him and in 1858, the United States Congress restored his pay.
