About this map

Casco Bay serves as a critical theater of coastal defense and maritime commerce in the mid-1940s. The map illustrates a heavily fortified landscape, where numerous military installations protect the approaches to Portland Harbor. Key positions include Fort McKinley on Great Diamond Island, Fort Scammel on House Island, and the land-based batteries of Fort Preble and Fort Williams. These sites, alongside a vast Army Reservation on Long Island, reflect the area's strategic importance during the World War II era.
