"He died in Paris at the age of 45 on 18 July 1792. He was buried in St. Louis Cemetery, which belonged to the French royal family. Four years later, France's revolutionary government sold the property and the cemetery was forgotten.
In 1845, Col. John H. Sherburne began a campaign to return Jones' remains to the United States. He wrote Secretary of the Navy George Bancroft and requested the body be brought home aboard a ship of the Mediterrean Squadron. Six years later, preliminary arrangements were made, but the plans fell through when several of Jones' Scottish relatives objected. Had they not, another problem would have arisen. Jones was in an unmarked grave and no one knew exactly where that was.
American Ambassador Horace Porter began a systematic search for it in 1899. The burial place and Jones' body was discovered in April 1905. President Theodore Roosevelt sent four cruisers to bring it back to the U.S., and these ships were escorted up the Chesapeake Bay by seven battleships.
On 26 January 1913, the remains of John Paul Jones were laid to rest in the crypt of the U.S. Naval Academy Chapel in Annapolis, Md.
Today, a Marine honor guard stands duty whenever the crypt is open to the public. Public visiting hours are from 9 a.m. to 4 p.m., Mondays through Saturdays, and from 1 p.m. to 4 p.m. on Sundays."
