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.
"The total booty of the winter battle in Mazurian Land, therefore, up to to-day rises to seven generals, more than 100,000 men, more than 150 cannon, and material of all sorts, inclusive of machine guns, which cannot yet be approximately estimated. Heavy guns and ammunition were in many cases buried by the enemy or sunk in the lakes; thus eight heavy guns were yesterday dug out or hauled out of the water near Lötzen and Lake Widmin.
"The Tenth Russian Army of General Baron Sievers may, therefore, now be considered as completely annihilated."
This summary was corrected in a later announcement, which stated that the number of guns taken as booty in the pursuit after the winter battle in Mazurian Land had risen to 300, including eighteen heavy guns. This was published on the 23d of February. In an announcement of the 26th of February the Great Headquarters amplified its account of the victory with this statement:
"In the Russian official report the extent of the disaster in the winter battle of Mazurian Land is either concealed or an attempt is made to obscure it. It is unnecessary to go further into these denials. As evidence of the extent of the defeat, the following list of the positions held by the captured generals, however, may serve:
"Of the Twentieth Army Corps: the commanding general, the commander of the artillery, the commander of the Twenty-eighth and Twenty-ninth Infantry Divisions, and of the First Brigade of Infantry of the Twenty-ninth Infantry Division. The commander of this latter division succumbed to his wounds soon after being made prisoner.
"Of the Third Army Corps: the commander of the Twenty-seventh Infantry Division and the commander of the artillery and of the Second Infantry Brigade of this division.
"Of the Fifty-third Reserve Division: the division commander and the commander of the First Infantry Brigade.
"Of the First Siberian Cossack Division: a brigade commander."
