Russia still clings tenaciously to Uzsok, however, doubtless having under consideration the possibility that Italy may enter the war, and that another advance against the Carpathians may then be made. In such a contingency the Russian losses in the various engagements around Uzsok would not have been in vain. Russia has answered the Austrian drive from the west by a vigorous offense against the defenses of Bukowina Province. The Austrian forces east of the San River are divided--one part which has been extremely active against the Russians being on the east bank of the Stryi, and the other, which has been quiescently defensive, along the Bistritza, the latter line running almost due east and west. This latter force the Russians struck, using large bodies of Cossack cavalry in a flanking movement from the north. The Austrian retreat has been more precipitate, and the losses greater in proportion than in the Russian retreat from the Dunajec. If in addition the Rumanians came across Transylvania and caught the Austrians in the rear the defeat would almost offset that of the Russians in the west. Rumania's advent into the war is, however, still a matter of doubt, and any conclusions predicated on that assumption are entirely speculative. The two known facts in regard to the Galician situation are that in Western Galicia the Russian Dunajec line is retreating, uncovering and therefore involving in its retreat the troops in the Carpathians, and in Eastern Galicia the Russians seem to have the greater measure of success. Of the two, however, the operations in Western Galicia are of infinitely greater importance. Eventually the Russian retreat will probably reach the general line of the San River north of Jaroslau, where there will be an opportunity to re-form on a much shorter line, and after recuperation of men and supplies preparations for a new offense may be begun. [Illustration: Operation on the Russian Front This map records the action for the week ended May 15. In the extreme north, in the Russian Baltic Province of Courland, the Germans still held the port of Libau, (1,) and a fierce battle was in progress south of Shavli, (2,) where the Russians stopped the raid toward Mitau. In South Poland and West Galicia the changes brought about by the great Austro-German drive of 1,500,000 men from Cracow are shown by the heavy dotted and solid lines. The dotted line shows the approximate position of the German battle front when the drive began and the solid line its approximate position according to latest advices from Berlin and Vienna, Jaroslau (3) being the latest important position reported captured. In extreme Eastern Galicia the situation was reversed, the dotted line showing roughly the position of the Russian line when the counter-drive by the Czar's forces was launched and the solid line its position, so far as was ascertainable, on May 15.]
