Secretary of War Henry Dearborn authorized construction of Fort Preble in 1808 with his son, Massachusetts Militia officer and future general Henry A. S. Dearborn, supervising the construction. The fort was named in honor of Commodore Edward Preble, who led a squadron of American warships during the Barbary Wars. Preble died in Portland in 1807 and is buried there.
