created on march 23, 1939, under gen. juliusz rómmel. "armia łódź" was to become a bolt between armies "kraków" and "poznań". however, because of mistakes committed by gen. rómmel, the army was located too close to the german border and joined fighting from the very beginning of the campaign, which deprived it of any possibilities of cooperation with the surrounding units. it consisted of 4 infantry divisions and 2 cavalry brigades.
