One of the German leaders, describing this encircling movement to the southeast from the north in which he played a part, says: "The roads and the weather were beyond all description--twelve to fifteen degrees Reaumur, with a cutting wind and driving snow, with nothing to eat, as the field kitchens on these roads could not follow. During pauses in the march one could but lean against the wall of a miserable house or lie down in the burned-out ruins, without straw to lie on and no covering. Men and horses sank to their hips in the snow, and so we worked our way forward, usually only about two kilometers an hour. Wagons and horses that upset had to be shoveled out of the drifts. It was a terrible sight, but we got through. We had to go on without regard for anything, and the example of the higher officers did much."
Two Russian corps from the southern wing of the army retreating by the Suwalki-Sejny causeway and by the Ossowetz Railway, according to accounts from Russian sources, made their way out of the trap under heavy rear-guard fighting.
The escaped portions of the Russian army crossed the Bobr toward Grodno. From the direction of this Russian stronghold a desperate effort was made to relieve the four corps which were endeavoring to escape toward the fortress from the forest southeast of Augustowo into which they had been pressed by the Germans from the west and north. On the 21st of February came the final act in the great drama. The German troops pushed forward at their best speed from all directions toward the forest. The help that had been intended for them came too late. Concerning the captures of this day, the German Great Headquarters reported: "On the 21st of February the remnants of the Tenth Army laid down their arms in the forest of Augustowo after all attempts of the Russian commander of this army, General Sievers, to cut a way out for the encircled four divisions by means of those parts of his army which remained to him after escaping over the Bobr to Grodno failed with extremely heavy losses."
Summarizing the results of the entire battle in an announcement of the 22d of February, the German Great Headquarters said: "The pursuit after the winter battle in Mazurian Land is ended. In cleaning up the forests to the northwest of Grodno, and in the battles reported during the last few days in the region of the Bobr and the Narew, there have been captured to date one commanding general, two division commanders, four other generals, and in the neighborhood of 40,000 men, seventy-five cannon, a quantity of machine guns, whose number is not yet determined, and much other war material.
