with the right wing of Von Hindenburg's army along
the upper Zelvianka, a southern tributary of the Niemen. The rest of
Prince Leopold's army were making the Kobryn-Minsk railroad their
objective and were fighting on September 9, 10, and 11, 1915, for
possession of the station at Kossovo.

While Von Hindenburg's army group was occupied with the drive on Vilna
and Von Mackensen's forces advanced against Pinsk, Prince Leopold's
regiments, as we have learned, fought continuously in the sector
between the Niemen and the Jasiolda Rivers. The problem assigned to
them apparently was that of gaining the Vilna-Kovno railroad in order
to cut off the Russian retreat, and by the time Vilna fell, September
18, 1915, they had just succeeded in forcing a crossing over the Shara
River, which runs practically parallel to the Lida-Baranovitchy
section of the Vilna-Kovno railroad. In a way this gave them command
of that section; but they first had to cross the country between the
Shara and the railroad, over a width of about twenty miles. Although
they were reported on September 19, 1915, as participating in the
pursuit of the retreating Russians, they seem to have arrived just a
little too late to capture large numbers of them. In fact, not until
September 20, 1915, were they reported actually at Dvorzets, on the
Vilna-Kovno railway, while on that day the right wing of this army was
fighting west of Oshoff, which, indeed, is to the east of the
Brest-Litovsk-Minsk railway, but still a considerable distance (about
twenty-two miles) west of Moltshad, a little to the southeast of
Dvorzets; stormed Ostroff, and crossed the Oginski Canal at Telechany,
after first throwing the Russians across it. These operations netted
some 1,000 prisoners. September 22, 1915, brought their left wing
about ten miles farther east at Valeika, while farther south the
fighting continued in the same locality as on the previous day during
the following days. By September 23, 1915, the left wing again had
advanced about ten miles along the Servetsh River at Korelitchy, as
well as the Upper Shara, east of Baranovitchy and Ostroff. The Russian
resistance along this river was maintained during September 24, 1915,
although the Germans gained its eastern bank south of Lipsk.

Just as in the Vilna-Niemen sector to the north, the German advance in
the region bounded in the north by the Niemen and in the south by the
Jasiolda was halted during the last week of September, 19
