"The task of the new troops sent to East Prussia was to defeat our Tenth Army, which held strongly constructed positions along the Angerapp. To assure the success of the undertaking the Germans brought a portion of their forces from the Bzura and Rawka fronts to the right bank of the Vistula. A movement of the Germans in East Prussia already became noticeable on the 4th of February, 1915. But the extent of this movement could only be recognized a few days later. As our leaders, because of the lack of railroad lines, could not collect the necessary forces on the East Prussian front with the necessary speed to meet the hostile attack adequately, they decided to take back the above-mentioned army of East Prussia to the border. In this movement of the right wing the Tenth Army, which was pressed by heavy hostile forces and threatened with being surrounded from the right, was forced to make a rapid change of alignment in the direction of Kovno. In this rapid movement a corps was separated from the rest of the army. The other corps which continued the battle obstinately without interruption, slowly drew back in the prescribed direction, bravely repelling the enemy and inflicting upon him heavy losses. Our troops overcame unbelievable difficulties, which were caused by the snow which filled all roads. As the streets were impassable, automobiles could not run. Trains were delayed and frequently failed to arrive at their destination. Our corps which formed the left wing of the Tenth Army held the enemy, while drawing back step for step for nine days on a stretch of territory which ordinarily is covered in four days. On the 19th of February these corps withdrawing by way of Augustowo left the battle field and took the position assigned to them. Further battles developed in the region before Ossowetz, on the roads from Lomza to Jedwabno and to the north of Radislow, also halfway between Plozk and Plonsk. These battles were in places very intense." An English authority says: "The chief Russian loss was in General Bulgakov's Twentieth Corps, which the German staff asserted they had completely destroyed. But during the fortnight which ended on Saturday the 20th, at least half of that corps and more than two-thirds of its guns safely made their way through the Augustowo and Suwalki woods to the position which had been prepared for the Russian defense. The total Russian losses may have been 80 guns and 30,000 men; they were no more. The two southern corps, in spite of their stubborn action at Lyck, crossed the woods between Augustowo and Ossowetz without serious disaster." CHAPTER LI BATTLES OF PRZASNYSZ--BEFORE MLAWA
