The port of Mobile, in Alabama, had been a rich and profitable port for centuries when the Second Great Depression began. It had a long history in the shipbuilding industry, and had been one of the major yards during World War II a century before. But it had only a minor and short history as a military port compared to others. Naval Station Mobile had been closed over half a century before, and there were no reserve naval forces in the area. In an America that had been cutting back on military spending for decades, Mobile had no effective history as a major naval military port. The Second Great Depression caught them woefully unprepared for the day when ships from other States would defend them from attacks. Not that there had been many attacks in the Gulf of Mexico they needed to prepare against, of course.
