[Edward L. Beach, The United States Navy, A 200-year History, chapter 8, The Gun and the Ship] 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.
Captain Stockton wanted his ship to carry two long guns, so he designed and directed the construction of "Peacemaker", another muzzleloader, by
Hogg and DeLamater of New York City. "Peacemaker" was built with older

technology, creating a larger gun of more impressive appearance but lower strength.
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."
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 , 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.

The guests aboard viewed the first set of firings and then retired below decks for lunch and refreshments.

Aftermath
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". He said it should not affect lawmakers' positive assessment of Stockton and his improvements in ship construction.

Plans to construct more ships modeled on ''Princeton'' were promptly scrapped. Still, Tyler won Congressional approval to construct a single gun on the dimensions of the Peacemaker, fired once and never mounted.[ A Court of Inquiry investigated the cause of the explosion and found that all those involved had taken appropriate precautions.][ At Stockton's request, the Committee on Science and Arts of the ]Franklin 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 the ''Oregon''.[ Ericsson, whom Stockton had originally paid $1,150 for designing and outfitting ''Princeton'', 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.][ Stockton went on to serve as Military Governor of California and a United States Senator from New Jersey.

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." 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. They had seven children before Tyler died in 1862, and his wife never remarried. In 1888, Julia Gardiner told journalist Nellie 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. Some historians question her account.[
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 by Thomas Rodman and John A. Dahlgren.
