Battery 204 #2858817
Description
In 1942, a site of a state park was condemned and purchased by the United States government for the construction of Fort Dearborn as part of an across-the-board modernization of US coast defenses. Fort Dearborn was primarily acquired to build a battery of two 16-inch (406 mm) ex-Navy guns, heavily protected by concrete and earth casemates. This was completed and test-fired in June 1944. Battery 204, consisted of two 6-inch (152 mm) M1 guns in shielded barbette mounts with a large bunker between them containing magazines and fire control facilities.
