The earliest forts established by the Danes, Dutch, English, Portuguese, Swedes and Mexicans and by the temporary appearance of the Russians are detailed. he colonial American forts, many of which were previously established by the European Powers, are covered in detail. Beginning with the American Revolution, each of the American military fortifications, militia forts, settler's forts and blockhouses, are offered.
