“That is what started the fight but, even after the Poles had retreated from Belorus/Ukraine, the Soviets tried for Warsaw.”
Warsaw was part of Russia at the start of WWI; I guess they wanted it back after losing it for 2 years (the same way Poland initially wanted land they viewed as theirs).
I have no horse in this race; I am not Eastern European, and if anything have more affinity for Poles than Russians.
