After tricking Elevian forces with a smaller invasion, most of them moved there. We were able to establish an armoured spearhead before their troops arrive, fortifying forces on the land we take. We encircle Henson and most of the Elevian industry.
IF you try and say that you have forts, they take time to build, at least 2 years, also Germany didn't remilitarize until after hball came, which was 15 years after the war. It is 1924. You are done, your military is still dead. We have your capital encircled, the last costume is our demands. The territorial demands are negotiable but we just want you to exit the war peacefully.
