Poland acquired four Gotha G.IVs and one G.III in the Wielkapolska region during the insurgencies and insurrections following the end of WW I. It is said that one was assembled from captured parts.
This subject was the only one that was used in combat. Originally it had the German number 213/17 and was taken over by Poles after it forced landed near Nowy Tomyśl on 16th January 1919. From there it was transported to Poznań and completely renovated. There it received a new number 100/17.
While expanding the Wielkapolska air force it was decided to form an Eskadra Niszczycielska, literally destroyer but perhaps better translated as bombardment. Formation started on 15th April 1920 at Poznań, initially with six AEG C IVs and one Gotha G.IV, and was named 21st Eskadra Niszczycielska. During the next month, the Gotha undertook several sorties, bombing armored trains and Bolshevik positions. In June armored trains and train stations were bombed.
From the end of 1920 it served with the 6th Eskadra at Lwów completing several flights against the Bolshevik cavalry in the area of Brody. On 3lst it suffered some light damage during landing after a flight test. In early September, he was sent to Poznań, where according to some sources was used in October of 1920 as a transport for the French military mission in Poland.
