Kutno Operational Group, named after the town and major rail junction of Kutno, (central Poland), was an Operational Group of the Polish Army, created in March 1939, a few months before the Invasion of Poland.
By Sunday, September 3, the regiments arrived at the Kutno rail station, and on the next day they reached Wloclawek, where they were incorporated into Pomorze Army, as the so-called Detachment of Colonel Sadowski (Oddzial Wydzielony podpulkownika Sadowskiego).
These regiments were the only units of the projected Kutno Operational Group, which reached the concentration area.
Due to worsening situation of the Polish Army, which was forced into a general retreat, on September 3 Polish Commander in Chief, Marshal Edward Smigly-Rydz abandoned the idea of creation of the Kutno Group.
On that day, 24th Infantry Division was transferred to Karpaty Army, and on September 4, the 5th I.D.
