If we are talking about the months of August to December 1917 then no. Russian soldiers were pretty much inactive on all fronts.
Again you fail to take in strategic situation on the entire front.
http://www.absoluteastronomy.com/top...n_(World_War_I)On August 27, three Romanian armies launched attacks through the Southern Carpathians and into Transylvania. The attacks were initially successful in pushing weak Austro-Hungarian units out of the mountains, but the Austro-Hungarians sent four divisions to reinforce the Austro-Hungarian lines, and by the middle of September, the Romanian offensive was halted. The Russians loaned them three divisions for operations in the north of Romania but very few supplies.
The first counterattack came from General August von Mackensen in command of a multi-national army of Bulgarian divisions, some Ottoman divisions, and a German brigade. This army attacked north from Bulgaria, starting on September 1. It stayed on the south side of the Danube river and headed towards Constanţa. The Romanian garrison of Turtucaia, encircled by Bulgarian troops (aided by a column of German troops) surrendered on September 6 (see: Battle of Turtucaia).
On September 15, the Romanian War Council decided to suspend the Transylvania offensive and destroy the Mackensen army group instead. The plan (the so-called Flămânda Maneuver) was to attack the Central Powers forces from the rear by crossing the Danube at Flămânda, while the front-line Romanian and Russian forces were supposed to launch an offensive southwards towards Cobadin and Kurtbunar. On October 1, two Romanian divisions crossed the Danube at Flămânda and created a bridgehead 14 kilometer-wide and 4 kilometer-deep. On the same day, the joint Romanian and Russian divisions went on offensive on the Dobruja front, however with little success. The failure to break the Dobruja front, combined with a heavy storm on the night of October 1/2 which caused heavy damages to the pontoon bridge, determined Averescu to cancel the whole operation. This would have serious consequences for the rest of the campaign.
Irrelevant. The annexation of Bessarabia was done with the consent of all sides involved.
So Germany signed the armistice the day after Romania re-entered the war so the war hadn't ended yet. You really should read what you write before you post my friend. The armistice signed on 3 November was between A-H and Italy only so again stop twisting the facts.
The Brusilov Offensive was in 1916.
http://en.wikipedia.org/wiki/Brusilov_Offensive
Brusilov's operation achieved the original goal of forcing Germany to halt its attack on Verdun and transfer considerable forces to the East. It also broke the back of the Austro-Hungarian Army which lost nearly 1.5 million men (including 400,000 prisoners). The Austro-Hungarian Army was never able to mount a successful attack from this point onward. Instead it had to rely on the German Army for its military successes.

The Offense ruined Austria-Hungary. Weakened by political turmoil, Austria was unable to cope with its losses, of funds and of soldiers. It was forever eliminated as a major military power. The future brought the collapse of the Habsburg Empire and the formation of the Austrian and Hungarian republics.
From Erich von Falkenhayn on 04/06/1916:
In the east of Lutsk Russians broke through into the centre front of Austrians. In two days they lost a 50km front. Austrian 4th army was annihilated except a few. In Bukovina Austrian 7th army was in critical situation and retreated. It was clear enough that Galicia faced crisis.
A-H forces were thrown about by Serbian forces in 1914 and quite convincingly too. The Romanians halted the Transylvanian Offensive because of strategic considerations elsewhere.
