At the end of August 1915, the Austro-Hungarian command plans a major offensive on Rovno by the forces of the 1st and 4th armies.

At the same time, the 2nd, 7th and German Southern armies were to finally oust the Russian troops from the borders of Austria-Hungary and, if possible, occupy Podolia.

The Central Powers managed to concentrate numerically superior forces, especially on the right flank of the 8th Russian Army.

A significant superiority in manpower was countered by marshy terrain cut by rivers and destroyed roads in the rear.

The reason for the failure was that in the midst of the attack, the 39th Army Corps ran out of cartridges for the Japanese rifles with which it was armed.

After regrouping, the Austro-Hungarian troops continued their offensive, which on September 3-4 ran into stubborn resistance from the Russian 8th and 11th armies.

[14] On September 8, the 10th Corps of the 4th Austro-Hungarian Army attacked Klevan and Tsuman, but due to rains, the floodplain of the Putilovka River turned into a swamp, and progress was slow.

On September 15-16, in stubborn battles, the Austro-Hungarian positions on the Stubel River were broken through by the shock group of the 8th Army.

On September 16-17, the 2nd and Southern armies ousted the Russian troops from the western bank of the Strypa River with counterattacks.

P. Makhrov, head of the operational department of the headquarters of the 8th Army, called the days of September 19-22 "gifted to the enemy."

At the request of the Austro-Hungarian Army High Command, Erich von Falkenhayn transferred the German 24th Reserve Corps to the ally.

[19] The Rovno offensive did not lead to the achievement of the goal set by the Austro-Hungarian Army High Command.

A small part of Eastern Galicia was still occupied by Russian troops, The Dual Monarchy managed to capture Lutsk and part of Volhynia and Polesia, but the Russian troops turned the tide of the operation, inflicted a strong counterattack on the Austro-Hungarians and heavy losses.

The result of stubborn and bloody battles in the autumn of 1915 in Galicia and Volhynia, as well as in Belarus and the Baltic states, was the transition of the forces of the Central Powers to strategic defense.

[20][21] Decisive actions of the Russian command during the entire campaign in favor of the Entente, revealed the weakness of the Austro-Hungarian troops, which then allowed another offensive to be launched in Galicia.
