A gun on USS Princeton explodes while the boat is on a Potomac River cruise, killing six people, including two United States Cabinet members.
The first USS Princeton was a screw steam warship of the United States Navy. Commanded by Captain Robert F. Stockton, Princeton was launched on September 5, 1843.
On February 28, 1844, during a Potomac River pleasure cruise for dignitaries, one gun exploded, killing Secretary of State Abel P. Upshur and Secretary of the Navy Thomas Walker Gilmer, and injuring others, including a United States Senator and Captain Stockton. The disaster on board the Princeton killed more top U.S. government officials in a single day than any other tragedy in American history. President John Tyler, who was aboard but below decks, was not injured. The ship's reputation in the Navy never recovered.
