We left Von Emmich and General Martiny with the Bavarians and the Tenth Austro-Hungarian Army Corps on their arrival at Krempna on the night of the 4th, during which time the Russians were making desperate efforts to evacuate northern Hungary and the western passes. The main forces of Von Mackensen's "phalanx" were meanwhile pushing on toward Jaslo, still in Russian possession. On the hills west of the Wisloka the Russian rear guards had intrenched themselves and held their positions till nightfall on May 5, 1915, all with the object of delaying the Germanic advance sufficiently for their comrades to clear the passes. Then they fell back again and made a stand near Tarnoviec, about six or seven miles east of Jaslo, where they dominated an important strategic position. Between them and Jaslo two railways ran along the valley of the River Jasliska, forming a serious obstacle to Von Mackensen's advance so long as the Russians could hold it. It was imperative that they should be cleared out, but the task of carrying it through was a difficult one. The undertaking fell to the Hungarian troops of the Thirty-ninth Honved Division, who advanced to the attack again and again only to be driven back each time by the Russian fire from the heights. Big howitzers were called into play and soon demolished the positions. The Russians retired east of the Wistok, followed by Von Mackensen's Austro-Hungarian corps, while the Prussian Guards moved on toward Frysztak, where the Russian troops from the Tarnow sector had taken up positions after the retreat from Brzostek.
