Romania bows out.

The Romanians reached an accord with the Central Powers on this day in 1918.  

Maybe the Germans were winning?

The treaty had some odd results. Romania was left as a nation, but only a satellite nation of the Germans, giving up territory that it claimed, but gaining some too, resulting in a bigger Romania than there had been prior to its disastrous entry into the war, but one in which the Germans called the shots.

Romania's king refused to sign the treat it it was repudiated at the end of World War One.

Significant points were Romania returned  Southern Dobruja and ceded part of the same territory in the north to Bulgaria with the remainder of the territory in Central Power's control.  It ceded to Austria Hungaria passes in the Carpathians.  I leased its oil to Germany for ninety years (oh, the Germans and that Romanian oil).  The Central Powers recognized the union of Bessarabia with Romania, no skin off the Central Powers nose there however.  Finally, German civil servants had veto power over all decisions by Romanian cabinet ministers and to even fire Romanian civil servants.
