In 1949, Leuchtenberg was a small, agrarian nation, still struggling to rebuild itself. Although nominally a republic, the post-World War II reality in Leuchtenberg was that it was on the verge of becoming a military dictatorship, run by the infamous Colonel Cloud. The oppressed peasants had no access to radio communications or print media. Eventually and with great difficulty, a message was smuggled out of the country, appealing to the Blackhawk Squadron for help.
Colonel Cloud and his faction, along with seizing the country's only airport, and all broadcast facilities, had gotten control of some advanced atmospheric technology, with which they were able to place heavy clouds, in stable positions, above locations of their choosing. All Leuchtenbergian farmers backing the opposition faction were receiving this treatment, and their crops were withering.
When the Blackhawks arrived, a dispute arose between them and a uniformed squad of tax collectors, and a warning was sent to their leader. Colonel Cloud reacted by throwing an impenetrable cloud cover across the entire nation of Leuchtenberg. By noon that day, it was as dark as midnight in every corner of Leuchtenberg. The Colonel issued an ultimatum: the darkness would not be relieved until the good citizens of Leuchtenberg had driven out the Blackhawks. Cloud's agents-provocateur stirred up mobs to hunt for the foreign interlopers.
The cloud-manipulating equipment had been hidden in an extinct volcano, which was now wrongly believed to be active, thus it served to disguise the massive vapor formations rising and swirling above the cone. And although the tiny nation was far too poor to afford them, the government also had a large squadron of modern, catapult-launched fighter planes, which were sent to up engage the Blackhawks. Despite some excellent piloting, they fared poorly, and several were destroyed, but Blackhawk's own plane was also maneuvered into crashing. Partly by accident, Blackhawk landed inside the volcano, and there he found the cloud-creating device. Blackhawk fought and beat the workers operating it, and their armed supervisor, Vronk, then had a confrontation with Colonel Cloud, at the end of which Vronk was dead, Cloud was beaten senseless, and many of his bodyguards were as well.
Colonel Cloud was arrested personally by the Leuchtenberg Minister of Justice, and placed on trial for treason and murder. His cloud-manipulating equipment was adapted to be a boon to local agriculture.
