Breaking off relations between the Polish and German governments
– Relations between the Polish and German governments were broken off due to a number of factors. They included the aggressive policy of Deutscher Ostmarkenverein (the German Eastern Marches Society, also called the H-K-T), the expansion of “Heimatschutz” units and the lack of agreement on the future of the Polish territories of the Prussian Partition.
– The Commissariat of the Supreme People’s Council issued an appeal calling Poles to boycott elections to the National Assembly and the State Assembly in Berlin.
– Sub-units of the First Border Battalion, which in the presence of Colonel Józef Lewszecki, First Commander of the 9th Kalisz Military District took the “Rota” oath, arrived in Kalisz.
