When reports told Polish General Plisowski that scout elements from the 3rd Panzer Division were seen near the railway station at Żabinka, north of Kobryń, he sent PP55 to prevent his forces from being cut off. A platoon of five scout tanks left the train near Żabinka and attacked German armoured cars near a bridge on Muchawiec River. After three tanks were lost, the other two withdrew. A further attack by an assault platoon from the train failed. After a combined attack of the assault platoon and PP55 artillery, the Germans left the area of the Muchawiec bridge. When they returned, PP55 attacked another battle group of the 3rd Panzer Division (consisting of scout elements and the 5th Tank Regiment, supported by the 6th Battery of the 75th light artillery Regiment). After destroying a few armoured cars, the train withdrew towards Brześć and the train station was left in German hands.
