In September 1914, correspondence was interrupted for three entire weeks and, most unusually, the press no longer ran any reports on Mises's regiment.When, to the great relief of his family and friends his name was eventually mentioned in the  , Martin Nirenstein wrote him immediately: "this time too victory will be on the side of liberty."Meanwhile, his brother Richard was stationed in Baden near Vienna.He took the eight o'clock express to the city of Przemysl in his native Galicia, where he would join his unit, the field cannon regiment n° 30.
The time passed somehow and in the evening, around seven o'clock, Mises left the train in Przemysl, wishing his fellow travelers farewell. It was August 1, 1914. Austria-Hungary did not declare war until August 5, after the war between Russia and Germany had broken out.
Even then there was no significant fighting for another two weeks. This should have been easier for Austro-Hungarian and German troops because of the shorter distances, but the Russians had apparently begun preparations much earlier — shortly after the assassination of the Austrian Archduke on June 28.
The fundamental military problem for the Austro-Hungarian and German alliance was a three-front war with numerically superior enemies on all sides — in particular the sheer overwhelming numbers of the Russian army.
In 1914, Russia counted a population of roughly 173 million, as opposed to 68 million Germans and 50 million inhabitants of the Austro-Hungarian Empire.
The Austro-Hungarian state was the sole bulwark against the Russian hordes standing ready to invade the land and destroy its Western liberties.
Maybe this attitude toward politics was contradictory and anachronistic, but Mises believed he had no choice in the matter, and he continued to believe that all his life.Mises's battery constantly had to change position, often under fire.Heavy rainfall set in, hampered their movements, and proved that k.u.k. There was no hope of relief any time soon from the military bureaucracy, so Mises resorted to private initiative: he had his mother send clothes for his men.He was himself the special object of motherly care through the army postal system.Army had been thrown far back behind Przemysl and now stood with its back to the Carpathian Mountains.In the first few weeks and months of the war, almost no day went by that did not see entire k.u.k.Because of the immensity of the Russian Empire, its 250 potential divisions could not be mobilized quickly.
