In Lorraine during the night a French detachment penetrated the first and second line of German trenches at a point south of Leintrey. The defenders of these positions were put out of action and the French took about fifteen prisoners. In the region of Moncel another party of French raiders successfully carried out a surprise attack on German positions. On this last day of the month the British headquarters in France reported that during January they had captured 1,228 Germans, including twenty-seven officers. PART II--EASTERN FRONT CHAPTER XVIII THE NEW DRIVE AGAINST LEMBERG Coincident with their attempt to recapture Kovel, the Russians launched a new drive against Lemberg, the ancient capital of Galicia. This movement was a result of the successes which they had gained in the Bukowina and in eastern Galicia during July, 1916. By the end of that month, as has been previously told, the Russians had reconquered all of the Bukowina, overrun some of the most southern passes of the Carpathians, and were in possession of that part of eastern Galicia located north of the Pruth and Dniester Rivers and east of the Strypa River. Having gained these advantages, they now attempted to press them and attacked Lemberg both from the north and from the south. In the former direction they advanced from Brody and Tarnopol against the strongly held Styr and Bug line. In the south Lemberg was defended by the Dniester line. Before forcing this line it was necessary to capture Stanislau, an important point on the Czernowitz-Lemberg railway. Between the Bug and the Dniester lines of defense Lemberg was secured in the east, and still farther by a third line of natural defenses. This was formed by a series of northern tributaries of the Dniester, of which the most important were the Sereth, Strypa, and Zlota Lipa Rivers. The former two had already been crossed by the Russians, but there still remained the very formidable and extremely strong line of defenses along the last, which had more than once before proved very difficult to overcome. On the Russian side there were engaged in this struggle three army groups under Generals Sakharoff, Stcherbacheff, and Lechitsky. The Austro-German forces were divided into four groups under Generals Puhallo, Boehm-Ermolli, Von Bothmer, and Von Pfanzer-Ballin.
