Fort Baldwin

Fort Baldwin, a coastal defense land battery near the mouth of the Kennebec River in Phippsburg, Maine, United States, was named after Jeduthan Baldwin, an engineer for the Colonial army during the American Revolution. The fort was constructed between 1905 and 1912 and originally consisted of three batteries, all of which were removed in July 1924:

*Battery Cogan with two three-inch guns. Named in honor of a lieutenant in the 5th Continental Infantry during the American Revolution. Cogan, who had also been quartermaster of the 1st New Hamsphire Regiment, died August 21, 1778.

*Battery Hawley with two six-inch pedestal guns. This battery also housed the fort's original observation station and electric equipment. Named in honor of Brigadier General Joseph R. Hawley who served with distinction during the American Civil War.

*Battery Hardman with one six-inch pedestal gun. Named in honor of a Captain in the 2nd Maryland Regiment, Continental Army during the American Revolution. Hardman was taken prisoner at Camden, South Carolina and died while a prisoner of war on September 1, 1780.

During World War I, Fort Baldwin and Fort Popham held a garrison of 200 soldiers including the 13th and 29th Coast Artillery.

During World War II, between 1941 and 1943, D Battery, 8th Coast Artillery protected Fort Baldwin and its Fire Control Tower that could radio the precise position of enemy vessels to batteries in Casco Bay.
