July 25th Fairhaven Mass, Fort Phoenix and the battle off Fairhaven

I sort of backed into this fort, I was looking at some other material, and noticed this fort was here, so I got to it on the way back from Fall River today- it wasn't out of the way too much- 

Here's the skinny on Fort Phoenix: 

Fort Phoenix is an American Revolutionary War-era fort located at the entrance to the Fairhaven-New Bedford harbor, south of U.S. 6 in Fort Phoenix Park in Fairhaven, Massachusetts.  On September 5–6, 1778, Fort Phoenix was destroyed by the British when they were raiding the harbor. When it was rebuilt, it was given the name "Fort Phoenix" after the mythical bird that rose from its owns ashesThe British tried to seize Fort Phoenix in 1814, but they were scared off when they mistook the horn of a postman's bicycle as a sounding of charge.  The fort currently has five iron cannons mounted on reproduction wooden carriages. The cannons are Model 1919 24-pounders and were all made in the 1820s.

There is also a smaller cannon at the fort which was captured by the Continental Marines during the raid on Nassau in the Bahamas in 1776. This raid was the first amphibious landing on foreign soil by United States Marines.

The fort was originally built in 1775 and added to the National Register of Historic Places in 1972.

At the fort is a marker which is devoted to the battle off Fairhaven, back in the early days of the Revolutionary War-  

Built for harbor defense in 1775 Destroyed by the British September 6th 1778 Later rebuilt and now the property of the town of Fairhaven

The Battle off Fairhaven was the first naval engagement of the American Revolutionary War. It took place on May 14, 1775, in Buzzards Bay off Fairhaven, Massachusetts (formerly known as Dartmouth, Massachusetts) and resulted in Patriot militia retrieving two vessels that had been captured by HMS Falcon. The patriots also captured 13 crew of the Royal Navy, the first naval prisoners of the war

Winds up being a pretty significant little fort!  

Also, from the fort, you could see a lighthouse off in the distance, but I cannot identify it, it doesn't fit the maps I have-  for now, its the unknown light...
