Revolutionary War. The fort was first built
in 1775 and consisted of small breastworks to guard the mouth of the Machias
River. The first naval engagement of the Revolutionary War was fought
just offshore the fort five days before the Battle of Bunker Hill. The
British would later destroy the fort in the same year when it sent four
ships into the Machias Bay. The fort was rebuilt again in 1777 and was
named Fort O'Brien in 1781 - in honor of Captain Jeremiah O'Brien - a
revolutionary war hero from Machias, Maine.
War of 1812. In 1808-1809 a blockhouse,
barracks, and battery were constructed. During this time period there
was a four-gun crescent-shaped earthwork established. In 1814 the
British captured the fort and destroyed the barracks.
Civil War. In 1863, some earthworks were put
in and a battery of five guns emplaced adjacent to the ruins of Fort
O'Brien. However, this fort saw no action during the Civil War.
The fort was called Fort Machias during the Civil War.
