John Milton, a 1,444-ton vessel built in Fairhaven, Massachusetts, was wrecked on February 20, 1858 5 nautical miles (9 km) west of the Montauk Lighthouse, killing all 32 or 33 people on board, in one of the worst maritime disasters off the east coast of on Long Island, New York.

[1] Built in 1854, John Milton was captained by Ephraim Harding of Martha's Vineyard, with its home port at New Bedford, Massachusetts.

After loading a cargo of guano at the Chincha Islands in the Pacific Ocean off the coast of Peru, she returned to the United States from South America, stopping at Norfolk, Virginia, on February 14, 1858.

Captain Harding may have confused the Shinnecock Lighthouse at Ponquogue Point in Hampton Bays, which had been erected in his absence, for the Montauk Light, and ran aground off the shore at what is known today as "Ditch Plains".

Harding's body was returned home and is buried in the Village Cemetery in Vineyard Haven, MA.
