Apparently this obvious action of the Germans is exactly what happened. When their northern front had been combed, we find forces subtracted piecemeal from the north, reaching an aggregate of thirty divisions, or at least nearly fifteen divisions more than had been anticipated. The doom of Rumania was sealed. [Sidenote: Retreating armies must reach defenses.] What happened in the Russian effort to support Rumania is exactly what has occurred in nearly all the drives that I have been in during this war. An army once started in retreat in the face of superior forces can hold only when supported _en bloc_ or when it reaches a fortified line. The Germans with all their cleverness and efficiency were not able to stop the Russian offensive of 1916 until they had fallen back on the fortified lines of the Stokhod in front of Kovel. In the Galician drive against the Russians in 1915, the armies of the Tsar were not able to hold until they reached the San River, on which they fought a series of rear-guard actions. [Sidenote: Russian corps on Sereth line.] So it was in Rumania. The Russian corps arriving on the installment plan were swept away by the momentum of the advancing enemy, who could not be halted until the fortified line of the Sereth was reached. [Sidenote: Rumanians played the game.] [Sidenote: Russia in chaos.] Whether one blames the Allies for lack of vision or not, I think one must at least acquit Rumania of any responsibility for her own undoing. Her case as represented by the King seems a just and sufficient reason for her having entered the war. Her action during the war has been straightforward and direct, and I have never heard of any reason to believe that the King or the Rumanian High Command has ever looked back in the furrow since they made the decision to fight on the side of the Allies. They followed the advice given them as to their participation in the war. They have played the game to the limit of their resources and to-day stand in a position almost unparalleled in its pathos and acuteness. In front of them, as they struggle with courage and desperation for the small fragment of their kingdom that remains, are the formations of the Turks, Bulgars, Austrians, Hungarians, and Germans, with Mackensen striving to give them a death-blow. Behind them is Russia in chaos. German agitators and irresponsible revolutionists have striven in vain to destroy the morale of their army and shake their faith in their government and their sovereign. It is estimated that three million Rumanian refugees have taken shelter behind their lines. Their civil population, or that portion of it which remains, will this winter be destitute of almost every necessity of life. [Sidenote: Obligation of Allies to Rumania.]
