Germanic troops were building a wall against their exits before they had seriously thought of withdrawing. Escape was impossible for many of them; some had managed to get across the Dukla in time, while those left behind would either have to surrender or fight their way through the lines across their path in the north. At the same time they would have Von Bojna and Boehm-Ermolli on their tracks. To make matters worse, they were also being pressed severely from the Hungarian plains by the troops which hitherto stood inactive. The Second Austro-Hungarian Army (Boehm-Ermolli) was fighting on both sides of the range. Through Rostoki they attempted to separate the Russians around Zboro from those situated farther east at Nagy Polena. We have stated elsewhere that the Forty-eighth Division was severely handled. They were surrounded in the Dukla by an overwhelming superior force, but General Korniloff, the commander, with a desperate effort and no little skill, succeeded in hacking his way through the enemy's lines and bringing a large portion of his force safely out of the trap. Inch by inch the Russian rear guards retreated, fighting tooth and nail to hold the pass while their comrades escaped. No less brave were the repeated charges made by the Austrians--clambering over rocks, around narrow pathways hanging high in the air, dizzy precipices and mountain torrents underneath. On Varentyzow Mountain, especially, a fierce hand-to-hand battle was fought between Hungarians and Cossacks, the latter finally withdrawing in perfect order. To conduct a successful retreat in the face of disaster is a no less difficult military achievement than the gaining of a decisive victory, and Brussilov's retreat from the passes deserves to rank as a masterly example of skillful tactics.
