Question....WOULD had Poles fighted along german troops against the Soviets if the pushes came to shove?
This epizode comes to my mind ... :
At a meeting in Paris in 1914, Piłsudski presciently declared that in the impending war, for Poland to regain independence, Russia must be beaten by the Central Powers (the Austro-Hungarian and German Empires), and the latter powers must in their turn be beaten by France, Britain and the United States.
Polish Legions (Polish Legiony Polskie) was the name of Polish armed forces created in August of 1914 in Galicia. Thanks to the efforts of KSSN and the Polish members of the Austrian parliament, the unit became an independent formation of the Austro-Hungarian Army. They were composed mostly of former members of various scouting organisations, including Drużyny Strzeleckie and Związek Strzelecki, as well as volunteers from all around the empire.
