(FOX NEWS) – Wisconsin researchers recently discovered a
145-year-old shipwreck in a murky river, and it was a complete
surprise. The vessel was found with sonar during the search for
a different ship.

Archaeologists were trying to map a different shipwreck, the
Berlin City vessel (shown below).

The Wisconsin Underwater Archaeology Association (WUAA),
the organization that led the trip, confirmed the discovery of
the L.W. Crane to Fox News Digital. The ship was found near
the city of Oshkosh.

Historians believe the vessel, built in 1865, sank in 1880. 

PT-109 was a US Navy patrol torpedo boat commanded by
Lieutenant (junior grade) John F. Kennedy during World War
II in the Solomon Islands.

His actions in rescuing his crew after the sinking earned him
a Navy and  Marine Corps Medal and contributed to his later
political career.             
         
        
   
     
       
         
     
       
        
       

PT-109, a film dramatizing this story, starring Cliff
Robertson as Kennedy, opened in 1963.

On August 2, 1776, members of Congress affixed their
signatures to an enlarged copy of the Declaration of
Independence.

Fifty-six congressional delegates in total signed the
document, including some who were not present at
the vote approving the declaration. The delegates
signed by state from North to South.
