USSPrinceton was ascrewsteam warship of theUnited States Navy. Commanded byCaptainRobert F. Stockton,Princeton was launched on 5 September 1843.
On 28 February 1844, during aPotomac River pleasure cruise for dignitaries, one gun exploded, killing six people, includingSecretary of StateAbel P. Upshur andSecretary of the NavyThomas Walker Gilmer, and injuring others, including a United States Senator and Captain Stockton. The disaster on board thePrinceton killed more top US government officials in one day than any other tragedy in American history.[1]PresidentJohn Tyler, who was aboard but below decks, was not injured. The ship's reputation in the Navy never recovered.
Princeton was the first ship with screwpropellers powered by an engine mounted below the waterline to protect them from gunfire.[2] Her twovibrating lever engines, designed byJohn Ericsson, were built byMerrick & Towne.[a] They burnedhard coal and drove a 14 ft (4.3 m) six-bladed screw. Ericsson also designed the ship's collapsiblefunnel, an improvedrange-finder, andrecoil systems for the main guns.[citation needed]
Twelve 42-pound (19 kg)carronades were mounted within the ship'sironhull.
Ericsson had also designed the ship to mount onelong gun.[citation needed]
The gun, asmooth boremuzzleloader made ofwrought iron, was built by the Mersey Iron Works, inLiverpool, England. It could fire a 225-pound (102 kg), 12-inch (300 mm) shot 5 mi (8.0 km) using a 50 lb (23 kg) charge. Its revolutionary design used "built-up construction", placing red-hot iron hoops around the breech end of the weapon, whichpre-tensioned the gun and greatly increased the charge thebreech could withstand.[6] Originally named "The Orator" by Ericsson, Stockton renamed it the "Oregon gun". It was shipped to the United States in 1841, where it was tested, reinforced to prevent cracks, and proof-fired more than 150 times.[citation needed]
Captain Stockton wanted his ship to carry two long guns, so he designed and directed the construction of "Peacemaker", another 12-in muzzleloader, byHogg and DeLamater of New York City. "Peacemaker" was built with olderforging technology, creating a larger gun of more impressive appearance, but lower strength.[7] Stockton rushed "Peacemaker" and mounted it without much testing. According to Kilner, "Peacemaker" was "fired only five times before certifying it as accurate and fully proofed."[6]
Attempting to copy the "Oregon gun", but not understanding the importance of Ericsson's hoop construction, Stockton instead heavily reinforced it at the breech simply by making the metal of the gun thicker, ending up with a weight of more than 27,000 lb (12,000 kg), more than half again as heavy as the Oregon gun. This produced a gun with the typical weakness of a wrought iron gun, the breech unable to withstand the transverse forces of the charge. This meant it was almost certain to burst at some point.[6]
Princeton waslaid down on 20 October 1842, at thePhiladelphia Navy Yard, as a 954long tons (969 t)screw steamer. The designer of the ship and main supervisor of construction was theSwedish inventorJohn Ericsson,[8] who later designedUSS Monitor. The construction was partly supervised by CaptainStockton, who had secured political support for the ship's construction.[citation needed] The ship was named afterPrinceton, New Jersey, site of anAmerican victory in theRevolutionary War and hometown of the prominent Stockton family. The ship waslaunched on 5 September 1843, andcommissioned on 9 September 1843, with Captain Stockton commanding.[8]
Princeton made a trial trip in theDelaware River, on 12 October 1843. She departed Philadelphia, on 17 October, for asea trial, proceeded toNew York, where she raced and easily beat the British steamerSS Great Western, and returned to Philadelphia on 20 October, to finish outfitting. On 22 November, Captain Stockton reported, "Princeton will be ready for sea in a week." On 28 November, hedressed ship and received visitors on board for inspection. On 30 November, she towedUSS Raritan down the Delaware, and later returned to the Philadelphia Navy Yard.Princeton sailed on 1 January 1844, for New York, where she received her two big guns, "Peacemaker" and "Oregon".Princeton sailed to Washington, on 13 February. Washingtonians displayed great interest in the ship and her guns.[8] She made trial trips with passengers on board down thePotomac River, on 16, 18, and 20 February, during which "Peacemaker" was fired several times.[9] The Tyler administration promoted the ship as part of its campaign for naval expansion, and Congress adjourned for 20 February, so that members could tour the ship. Former PresidentJohn Quincy Adams, now a congressman and skeptical of both territorial expansion and the armaments required to support it, said the Navy welcomed politicians "to fire their souls with patriotic ardor for a naval war".[10][11]

President Tyler hosted a public reception for Stockton in the White House on 27 February 1844.[12] On 28 February,Princeton departedAlexandria, Virginia, on a demonstration cruise down the Potomac with Tyler, members of his cabinet, former First LadyDolley Madison, SenatorsThomas Hart Benton of Missouri,Nathaniel P. Tallmadge of New York,William Cabell Rives of Virginia,Samuel S. Phelps of Vermont,Spencer Jarnagin of Tennessee,Edward A. Hannegan of Indiana, and about 400 guests. Captain Stockton decided to fire the larger of the ship's two long guns, Peacemaker, to impress his guests. Peacemaker was fired three times on the trip downriver and was loaded to fire a salute to George Washington as the ship passed Mount Vernon on the return trip. The guests aboard viewed the first set of firings and then retired below decks for lunch and refreshments.[13]
Secretary Gilmer urged those aboard to view a final shot with the Peacemaker. When Captain Stockton pulled the firing lanyard, the gun burst. Its left side failed, spraying hot metal across the deck[7] and fragmentation into the crowd.
Six men were instantly killed:
Another 16 to 20 people were injured, including several members of the ship's crew, Senator Benton, and Captain Stockton.[17][18] The president was below decks and not injured.[19]
Tyler had become president after the death ofWilliam Henry Harrison, and there would be no Constitutional mechanism to fill an intra-term vacancy in the position of vice-president until theTwenty-Fifth Amendment was ratified in 1967; therefore he had no vice-president. If Tyler had been killed in the incident, under theterms of the Presidential line of succession the currentPresident pro tempore of the SenateWillie P. Mangum would have becomeActing President.
Rather than ascribe responsibility for the explosion to individuals, Tyler wrote to Congress the next day that the disaster "must be set down as one of the casualties which, to a greater or lesser degree, attend upon every service, and which are invariably incident to the temporal affairs of mankind".[20] He said it should not affect lawmakers' positive assessment of Stockton and his improvements in ship construction.[21]
Plans to construct more ships modeled onPrinceton were promptly scrapped. Still, Tyler won Congressional approval to construct a single gun on the dimensions of the Peacemaker, fired once and never mounted.[21] ACourt of Inquiry investigated the cause of the explosion and found that all those involved had taken appropriate precautions.[21][f] At Stockton's request, the Committee on Science and Arts of theFranklin Institute conducted its own inquiry, which criticized many details of the manufacturing process, as well as the use of a welded band for reinforcement rather than the shrinking technique used on theOregon.[21] Ericsson, whom Stockton had originally paid $1,150 for designing and outfittingPrinceton, sought another $15,000 for his additional efforts and expertise. He sued Stockton for payment and won in court, but the funds were never appropriated.[21] Stockton went on to serve asMilitary Governor of California and aUnited States Senator from New Jersey.[22] Ericsson had a distinguished career in naval design and is best known for his work on USSMonitor, the U.S. Navy's firstironclad warship.
To succeed Gilmer as Secretary of the Navy, Tyler appointedJohn Y. Mason, another Virginian;[7]John C. Calhoun was Tyler's replacement for Secretary of State Upshur. Upshur was about to win Senate approval of a treatyannexing Texas when he died. Under Calhoun, annexation was delayed and became a principal issue in thepresidential election of 1844.[23]
Julia Gardiner, who was below decks onPrinceton when her father David died in the Peacemaker explosion, becameFirst Lady of the United States four months later. She had declined President Tyler's marriage proposal a year earlier, and sometime in 1843, they agreed they would marry but set no date. The President had lost his first wife in September 1842, and at the time of the explosion, he was almost 54. Julia was not yet 24. She later explained that her father's death changed her feelings for the President: "After I lost my father I felt differently toward the President. He seemed to fill the place and to be more agreeable in every way than any younger man ever was or could be."[24] Because he had been widowed less than two years and her father had died so recently, they married in the presence of just a few family members in New York City on June 26, 1844. A public announcement followed the ceremony.[25] They had seven children before Tyler died in 1862, and his wife never remarried. In 1888, Julia Gardiner told journalistNellie Bly that at the moment of the Peacemaker explosion, "I fainted and did not revive until someone was carrying me off the boat, and I struggled so that I almost knocked us both off the gangplank". She said she later learned that President Tyler was her rescuer.[26][g] Some historians question her account.[27]
The Peacemaker disaster prompted a reexamination of the process used to manufacture cannons. This led to the development of new techniques that produced cannons that were stronger and more structurally sound, such as the systems pioneered byThomas Rodman andJohn A. Dahlgren.[28]
During construction and in the years following, Stockton attempted to claim complete credit for the design and construction ofPrinceton.[citation needed]

Princeton was employed with theHome Squadron from 1845 to 1847. She later served in theMediterranean from 17 August 1847 to 24 June 1849. Upon her return fromEurope, she was surveyed and found to require $68,000 ($2.57 million in present-day terms) to replace decaying timber and make other repairs. The price was deemed unacceptable, and a second survey was ordered.[29] She was broken up at theBoston Navy Yard that October and November.[30][31]
In 1851, her "Ericsson semi-cylinder" design engines and some usable timbers were incorporated in the construction of the secondPrinceton.[32]
The "Oregon" gun is on display inside the main gate of theUnited States Naval Academy, inAnnapolis, Maryland.[33]
Theship's bell was displayed during the 1907Jamestown Exposition.[34] It was later installed on the porch ofPrinceton University's Thomson Hall,[35] which was constructed as a private residence in 1825, by Robert Stockton's father,Richard.[36] It is now on display at thePrinceton Battle Monument, nearPrinceton'sborough hall.[37]
