I’ve been doing Japanese history for fifteen years, now, and Chinese history for a decade, and I’ve never figured out why the Mongols, after their first attack failed, would make landfall at the exact same spot where they made landfall before and the Japanese had been building fortifications for over half a decade. Didn’t they have any advance intelligence? Was the cross-strait navigation really that difficult that no other option existed? Did the Koreans not care if the Mongols succeeded, and steer them into the waiting Japanese defenders? (OK, I know that’s not terribly likely, as thousands of Koreans were forced into service in the invasions as well.) This has always troubled me. Successive typhoons, the kamikaze, don’t bother me because freak natural occurences are beyond our ken or control. Inexplicably dumb human behavior troubles me.
