XVIII. Looking at the Neighbours
Having settled the Hungarian issue, the Romanian army was free to look for pray in other directions.
In the south there was its ally Greece, so it was impossible to do anything there. After all, they retreated quickly after liberating some Romanian land alongside the senior Entente members.
In the south-east was the corpse of the Ottoman Empire. However Constantinopole and the Straits were guarded by the French and British. So, nothing to do there as well.
In the south-west there were the Italians occupying parts of Albania, Dalmatia, Croatia and all of Slovenia. They had already evacuated Montenegro of course, since it was Romanian land. War with Entente member Italy was unimaginable, but the border must be agreed on somehow. Diplomacy there.
In the west was German-Austria self declared member of the German Empire but defeated and having an armistice with the Entente. Just like Hungary... First of all, it was not advisable to irritate the Entente again. And second, there was no need to invade German-Austria. There were no Romanians there and in the future it will be nicer to have a friendly German Empire as a neighbour instead of an irredentist vengeful one.
In the north there was this new Polish State sandwiched between Germany and Russia. Better have them as friends. Very few Romanians there as well.
In the east there was the Black Sea, but in the north-east?
Well in the north-east there was nothing. It used to be the Russian Empire there. But there is no Russian Empire any more. Just some kind of a freak state - communist Russia, far, far away.
On the other shore of the Prut River there was a huge abbyss streching on for hundreds or even thousands of kilometers with no stable political entity claiming it, where dozens of small groups fought each other and the German army incessantly. Communists, anarhists, socialists, monarhists, Russians, Ukrainians (what was this nation any way?!), Ruthenes, Little Russians, Tatars, Cossacks, Germans and Romanians. Lots of Romanians.
So, without any doubt, the way to go was to the north-east, deep into Russia.
But first of all, the Poles need a little help.
With Bucovina already in Romanian hands, the Romanian army pushed north, occupied Pokutia and pushed into Galicia destroying the Ruthenian (West-Ukrainian) army and linking with Poland on 12 December.
With that problem solved, the Romanian army finally crossed the Prut River and liberated Bessarabia on 16 December.
With Bucovina, Pokutia and Bessarabia annexed to Romania, finally, after hundreds of years, all the Moldavian lands of Stephen the Great (Ștefan cel Mare) were again under Romanian rule.
Transnistria (the territory between Dnester and Southern Bug) was quickly occupied by 20 December with the help of the dense Romanian population found there.
And on 23 December 1920 the Romanian army crossed the Southern Bug venturing deep into Russia.
At the same time, the German war machine was finally reaching its exhaustion point and the war on the Western Front was quickly approaching its end.
Romania had to act quickly. After all, this Russian adventure was supposed to happen because of the need to engage the enemy, the German army, wherever it may be. Not because of Romanian expansionist policy, right?
If the war was over the Entente might get strange ideas, like the "teritorial integrity of Russia" or the "creation of an independent Ukrainian State" or whatever!
That was the reason why Romania was in such a hurry and just before Christmas, after 4 and a half years of war, horrific death and destruction, sent its war-hardened army into the Russian abbyss, into the unknown. For yet another war!
