On August 17, 1916 Rumania settled the military alliance with the Allies which had been forced upon her, and after that instantly started to disprove the belief – nevertheless present among the great powers 50 years later – that the ally is undoubtedly superior to a neutral. The Allies had expected that the in excess of 500,000 men strong Rumanian forces would be dispatched to the south towards Bulgaria, after which probably link up with their own troops at Salonika.

How­ever, Rumanian territorial claims towards Bulgaria had been recently fulfilled by the Treaty of Bucharest of 1913 which had finished the 2nd Balkan War. In contrast, Rumania nevertheless had dreams, which were termed as ‘national aspirations’, for Austro-Hungarian Transylvania. So, on August 27, 1916, to the consternation of Allies and Central Powers as well, Rumania marched north.

Germany, which had been expecting that the Rumanian army would pro­crastinate a little bit longer, was ill-­placed to meet this fresh pressure: aid had been recently provided for Austria to halt the Brusi­lov offensive, the western Allies had been launching their Battle of the Somme simultaneously as their troops at Salonika had been starting to be way more effective.

So in the beginning the Rumanian army car­ried all in advance of it, taking the provincial capital of Transylvania at the beginning of September. How­ever, by solid organization and by choosing remarkable risks in scraping together reinforce­ments from peaceful areas of other fronts, the German high command did simply man­age to master the problem. Falkenhayn attacked the Rumanians in Transylvania, while Mackensen went through Bulgaria and attacked this new opponent from the south, driving the Rumanians out of their Dobrudja region.

At this point it turned out to be obvious that the Rumanian army was even worse skilled and even worse prepared than the pessimists had stated, and in nevertheless the easy-going Rumanian officers had been ill­adapted to modern warfare. The Ruman­ians requested Russian help, and it was Russian soldiers which inflicted a brief check on Mackensen in mid-September.

But Prior to the end of the month, regardless of Russian diversionary attacks farther north, both German armies had been threatening the center of Rumania. In the south Mackensen forced his adversary across the Danube, while the Rumanian forces which had so politely occupied Transylvania 30 days earlier, had been at this moment in complete re­treat.

On October 23, Mackensen cap­tured the key Black Sea port of Constanta, and within early December Bucharest was captured. The Rumanian military was now wiped out at this point: it defended with Russian help a small sector of Rumanian area close to Jassy and it was becoming restructured by a French general in the hope of better times to come.
