Second Serbian Campaign

Following the collapse of Serbia, Austro-Hungarian Empire (mostly without German help) concludes the fighting on the Balkan Peninsula... for now.

Serbia was the most powerful of the Entente countries in the western Balkans area. With it gone following the Bulgaria joining the war, the fall of the rest was merely the matter of time. Kingdom of Montenegro was squashed by Austro-Hungarian forces easily. Albania - seen by many as a fake state - was taken over right after that.   With that, all presence of Entente in the Balkans was reduced to a small bridgehead near Saloniki, in eastern Greece. Bulgaria annexed serbian Macedonia. The rest became a political battleground between Hungarian government that wanted Serbia merely occupied, while archduke Franz wanted to annex Serbia, Montenegro and perhaps even Albania (though there was also an idea about ceding southern part of it to Greece to make it join Central Powers) as a part of his plans of reforming Austro-Hungarian Empire into a union of equal states.
