To maintain its imperial power in America, Spain built fortifications
across the width of the continent. These outposts were established along
Spanish borders from the late sixteenth century onwards to defend its
interests against rival European powers and to suppress uprisings of the
Native Americans and local population. By the eighteenth century,
Spain's defenses spread from the northern area of the Gulf of Mexico
through to California. Some of these imperial fortifications, such as
the Alamo, played key roles in conflicts including the American
Revolution and the Texan War of Independence. This book provides a
cogent analysis of Spain's defensive network at the height of the
country's imperial strength on the American continent.
