At the beginning of the war neither side was prepared for the conflict as evidenced by their respective fortifications as many of the forts in the interior of the US and Canada were old, neglected, or hastily erected.  This illustrated volume of detailed sketches and maps along with present day photographs is authored by René Chartrand and illustrated by Donato Spedaliere.  This is #106 of the Fortress series of books by Osprey Publishing of Great Britain.  It measures about 7” by 10” and has 64 pages with an index.
