Swift and systematic and secret were their preparations, and their plan most excellent. So far as their knowledge went, America was the only dangerous possibility; America, which was also now the leading trade rival of Germany and one of the chief barriers to her Imperial expansion. So at once they would strike at America. They would fling a great force across the Atlantic heavens and bear America down unwarned and unprepared. Altogether it was a well-imagined and most hopeful and spirited enterprise, having regard to the information in the possession of the German government. The chances of it being a successful surprise were very great. The airship and the flying-machine were very different things from ironclads, which take a couple of years to build. Given hands, given plant, they could be made innumerably in a few weeks. Once the needful parks and foundries were organised, air-ships and Drachenflieger could be poured into the sky. Indeed, when the time came, they did pour into the sky like, as a bitter French writer put it, flies roused from filth. The attack upon America was to be the first move in this tremendous game. But no sooner had it started than instantly the aeronautic parks were to proceed to put together and inflate the second fleet which was to dominate Europe and manoeuvre significantly over London, Paris, Rome, St. Petersburg, or wherever else its moral effect was required. A World Surprise it was to be--no less a World Conquest; and it is wonderful how near the calmly adventurous minds that planned it came to succeeding in their colossal design.
