For the next three days Brussilov attempted to work his way to the rear of the Uzsok position with his right wing from the Laborcz and Ung valleys, while simultaneously continuing his frontal attacks against Boehm-Ermolli and Von Bojna. Cutting through snow sometimes more than six feet deep, the Russians approached at several points within a distance of three miles from the Uzsok Valley. But the Austrians still held the Opolonek mountain group in force. Severe fighting then developed northwest of the Uzsok on the slopes between Bukoviec and Beniova; the Russians captured the village of Wysocko Nizne to the northeast, which commands the only roads connecting the Munkacz-Stryj and the Uzsok-Turka lines. Though both sides claimed local successes, they appear to have fought each other to a deadlock, for very little fighting occurred in this zone after April 14, 1915. Henceforth Brussilov directed his main efforts to the Virava and Cisna-Rostoki sector. From here and Volosate, where there had been continuous fighting since the early days of April, the Russians strove desperately for possession of the Uzsok. They were ow only two or three days' march from the Hungarian plains. Between April 17 and 20, 1915, a vigorous Austrian counterattack failed to check the Russian advance. Between Telepovce and Zuella, two villages south of the Lupkow, the Russians noiselessly approached the Austrian barbed-wire entanglements, broke through, and after a brief bayonet encounter gained possession of two heights and captured the village of Nagy Polena, a little farther to the east. During the night of April 16-17, 1915, the Russians took prisoners 24 officers, 1,116 men, and 3 machine guns. On April 18, 1915, the Austrians directed several fierce attacks against the heights south of Telepovce, but were compelled to evacuate the approaches to their positions. Here, also, an Austrian battalion was cut off and forced to surrender. Meanwhile the fighting was gradually decreasing in intensity; the great Carpathian campaign had reached the end of another chapter. The Austro-German offensive had failed in its purpose. From Uzsok eastward there had been but little fighting after the Russian recapture of Stanislawow. CHAPTER XL CAMPAIGN IN GALICIA AND BUKOWINA--BATTLE OF THE DUNAJEC
