By the beginning of May, 1915, the spring floods had subsided, when operations became again possible. General Lechitsky, on the Russian side, probably aimed at recovering the Pruth Valley, while the Austrian commander, General von Pflanzer-Baltin, directed his efforts to establishing himself on the northern bank of the Dniester. He would then be able to advance in line with the Germanic front that was pressing on from the west, and northward from the Carpathian range between Uzsok and the Jablonitza passes; otherwise his force would lag behind in the great drive, a mere stationary pivot. At that time he held about sixty miles of the Odessa-Stanislau railroad (which runs through the valley via Czernovice and Kolomea) with the Russians only twenty miles north of the line. If that position could be taken the Austrians would have the South Russian line of communications in their hands, for it was along this line that supplies and reenforcements were being transported to Ivanoff's front on the Wisloka from the military centers at Kiev and Sebastopol. Thus the railway was of tremendous importance to both belligerents. What it meant to the Austrians has been stated; to the Russians its possession offered the only opportunity for a counteroffensive in the east that could possibly affect the course of the main operations on the Wisloka, San, and later the Przemysl lines. But however successful such a counteroffensive might prove, it could not have exerted any immediate influence on the western front. With the Transylvania Carpathians protecting the Austro-German eastern flank, there would still be little hope of checking the enemy's advance on Lemberg even if Lechitsky succeeded in reconquering the whole of the Bukowina and that part of eastern Galicia south of the Dniester. Every strategic consideration, therefore, pointed to the Dniester line as the key to the situation for the Austrian side, and Von Pflanzer-Baltin decided to stake all on the attempt.
