📗 Libro en inglés FORTRESS AMERICA : THE FORTS THAT DEFENDED AMERICA, 1600 TO THE P RESENT

So many forts were built--most in the 1800s--that there are few places in the continental United States more than 50 miles from a fort location. Yet, despite their prominence and importance, there has never been--until now--a single volume devoted to American forts and homeland fortification defense. From the earliest colonial settlements to Cold War bunkers, the North American continent has been home to thousands of forts and fortress structures. "Fortress America" surveys the broad sweep of fortifications throughout North America-from seacoast forts of the late eighteenth century to wooden inland forts built to defend against Native American, English, French, or Spanish attack; from Civil War-era coastal and inland waterways forts to the Great Plains'' forts of the Old West; from World War II subterranean bunkers to Cold War concrete missile silos. The text of "Fortress America" is complemented with never-before-published photographs, and extraordinary drawings, cut-aways, and diagrams illustrating the design and structure of American forts.
