The Ruhr District is the industrial heart of Germany and the most essential part of this industrial superpower. Even though it suffered looting and occupation after World War I, it quickly regained its vitality.
If one could occupy the Ruhr District and seize some important industrial equipment and skilled workers, it would be very helpful for the future development of Australasia's industry.
However, such an assault was very challenging. At that time, a large part of French territory, including Paris, was still occupied by Germany, and the Ruhr District was located quite deep within.
For the Australasia Army to occupy the Ruhr District, they had to maneuver behind the German Army's Westline.
The difficulty of this task can be imagined, although conquering the Ruhr District would yield great benefits, completing this task would also be a great challenge.
