Operation persische Nacht

[Bavarian Empire]

After Iraq was brought into the Reich, various tribes to the east have been raiding Bavarian oil fields. The Reich has sent 10 million men eastward to conquer all open space for the Empire, and to bring order and civilization to the tribes.

(I'm claiming all the available land to my east in the nation of Bahrain and the open Iranian lands. Yes, all of it, as all the nations around me are inactive and they won't colonize it anyway.)

[Bavarian Empire]

Reich forces, enveloping and subdueing tribes in Bahrain and Persia, the army gets enveloped in a siege with the Caucasian tribes, who have entrenched themselves in the mountains. After a few weeks and an almost constant artillery barrage, even these tribes are subdued.
