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 now 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.
So deep was the snow in places that movement was impossible; the trampling of the charging battalions rushing down over the slopes dislodged avalanches of snow, overwhelming both attackers and defenders. By April 1, 1915, the Russians approached Volosate, only twelve miles from the rear of the Uzsok Pass, from which they were now separated by a low ridge.
