While the East Prussian Battle was underway, the Russia-Austria border was not idle. Urged by Germany, the Austro-Hungarian Empire assembled three army groups, totaling 48 infantry divisions and 11 cavalry divisions, preparing to launch an attack on Russia nation.
On the Russian side, they had accumulated the Third, Fourth, Fifth, and Eighth Army Groups, intending to take the whole of Galicia in one battle.
If the East Prussian Battle was a hastily fought war, Russia nation had no choice but to embark on under pressure from the British and the French.
Then the encounter between the Russian and Austro-Hungarian forces along the border revealed the ambitions of the Austro-Hungarian Empire and Russia nation in this war.
The Austro-Hungarian Empire wanted to defeat Russia nation, march southwards, and become the only powerful nation in the Balkan region, taking over all Balkan states.
