chance of putting a new obstacle into
the thorny path of the advancing invader. Whenever the latter seemed
to ease up for a moment, either to gain contact with his main forces
or to rest up after especially severe forced marches, the Russians
were on hand with an attack. But just as soon as the attack had been
made the Germans or Austrians or Hungarians, or all three together,
were ready to forget all about the temporary let-up and were prepared
to meet the attack. Then once more the pursuit would begin.

During the drive on Brest-Litovsk, covering practically all of August,
1915, after the fall of Warsaw, the operations of Von Mackensen's
southern group were so closely connected and intertwined with those of
the central group that they have found detailed consideration together
with the latter. During all this time the extreme right wing in
Eastern Galicia did comparatively little beyond preventing an advance
of the Russian forces at that point. With the fall of Brest-Litovsk,
however, and the beginning of the Russian retreat along the entire
front, activities in the southeastern end of the Russo-German-Austrian
theatre of war were renewed.

On August 28, 1915, German and Austro-Hungarian forces under Count
Bothmer broke through the Russian line along the Zlota-Lipa River,
both north and south of the Galician town of Brzezany, about fifty
miles southeast of Lemberg, and in spite of determined resistance and
repeated counterattacks drove the Russians some distance toward the
Russo-Galician border. At the same time other parts of Von Mackensen's
army successfully attacked the Russian line at Vladimir Volynsky, a
few miles east of the Upper Bug and somewhat north of the
Polish-Galician border. The combined attack resulted in a gradual
withdrawal of the entire Russian line as far as it was located in
Galicia, aggregating in length almost 160 miles. These operations
alone netted to the Austro-Germans about 10,000 Russian prisoners.
This attack came more or less unexpectedly, but in spite of that was
carried on most fiercely. By August 30, 1915, the right wing had
forced the Russians back to the river Strypa and was only a few miles
west of Tarnopol.

Farther north another army under the Austrian General
Boehm-Ermolli encountered determined resistance along the line
Zlochoff-Bialykamien-Radziviloff, where the Russians were supported by
very strongly fortified positions. Still farther north the attack
progressed in the d
