On January 17, 1919, Polish reconnaissance planes were sent into German territory, and in mid-March, 1st Greater Poland Field Squadron was created. This unit was soon sent to the area of Lwow, to fight in the Polish–Ukrainian War, so 2nd Greater Poland Field Squadron was created to watch the skies over Greater Poland. This squadron was also sent to Eastern Galicia: in mid-June 1919, it was relocated to Stryj, taking part in the Polish–Soviet War.
