May 1917: The Seven-Power Plan for the Balkans
The Ottoman Empire has now surrendered. Syria and Mesopotamia join Palestine and Arabia as independent states under British protection, while Turkey itself is under French military administration.
The effect on Central Powers morale has been catalcysmic. Germany is on 18% (9.4k) and Austria-Hungary, 11% (3.6k). Russian morale has risen to 35% (16k). Furthermore, the Russian Provisional Government seems to be succeeding at rebuilding the Army, so there is no imminent threat of Russia being overwhelmed. In bad news though, Bolshevism is spreading in the Russian army and there is still a major risk of a Russian surrender in the long term.
Time to seize the opportunity and mount an offensive in the now-very-large Balkan theatre that can knock Austria-Hungary out of the War.
The Entente coalition here is composed of the local powers Montenegro, Serbia, Greece and Romania as well as Britain, France and Russia. Of course there are many other nationalities involved - Algerians and Moroccans in the French army, Indians and Australians and New Zealanders and Canadians in the British. The Western powers have several armies available now the Turks are finished. The plan is as follows
French Expeditionary Force under Dubail will move NW, finishing off the Bulgarians and move into Romania then push through the Transylvanian mountains onto the plain of the Danube, probably at the Iron Gates gorge. The Romanians and Russians will assist.
British Army of Turkey under Haig (which includes the Greeks) will move to assist the Serbian National Army around Nish and pushing on Belgrade and then into Slavonia. The Marines will detach for potential amphibious operations in the Adriatic.
British Army in of the Balkans under Hamilton will hold its positions around Uzice and support offensives on either its left or right flanks. (You will note that Sarajevo is back in enemy hands; this was a planned withdrawal as the position had become overextended.)
The British Army of Palestine under Smith-Dorrien will take transports to Montenegro and commence a push along the Adriatic coast. The Marines units will be attached to this force - if the Adriatic can be cleared of Central Powers submarines (which is a big 'if'), then they will conduct amphibious operations in the enemy's rear.
The overall concept is that this flurry of simultaneous blows will overwhelm the Central Powers at several points and provide a decisive end to Austria-Hungary as a political entity. If Austria-Hungary can be defeated then Germany will not be far behind.
No-one is putting dates on anything, but it seems likely the war will be over before the next winter.
