In the interbellum Poland, headquarters of the Polish Army frequently organized huge military manoeuvres on the territory of the Volhynian Voivodeship. These war games would take place in early fall, right after harvest. Most probably, they were organized on the real estates, whose owners were mostly Polish members of upper classes (szlachta). Local Ukrainian peasants, who made a majority of inhabitants of Volhynia, frequently complained about these events.
