units. Moreover, a large number of newly mobilised reservists started to arrive at the fortress, awaiting forward deployment to their units. From these units General Konstanty Plisowski organized a force of roughly three infantry battalions, aided by an engineering battalion, several batteries of artillery and two companies of old FT-17 tanks used for training, Nos. 112 and 113. Opposing forces The city of Brześć was defended by a small improvised force under General Plisowski. The Polish forces consisted of three infantry battalions, one engineering battalion, some artillery and were assisted by two armoured trains (designated PP55 and PP53) commanded by Captains Mieczysław Malinowski and Andrzej Podgórski. The German forces consisted of the entire XIX Panzer Corps under General Heinz Guderian. Battle On 14 September 77 German tanks of the 2nd Battalion of the 8th Panzer Regiment, part of 10th Panzer Division, reached the area of Brześć and attempted to capture the fortress on the run.

All the Polish tanks were destroyed, but the German forces were forced to retreat towards their initial positions. Polish armoured train number 53 (PP53), which made a reconnaissance advance to Wysokie Litewskie, was attacked by a scout patrol from the 10th Panzer Division. The crew from the train opened fire with artillery. Several other skirmishes were fought, but were largely inconclusive. Later that day the German artillery arrived and started bombardment of both the fortress and the town. Heavy street fighting ensued. At dawn approximately half of the town was in German hands, the other half being defended by Polish infantry. Polish anti-tank weapons, artillery and AA guns were very scarce and were unable provide enough support for the infantry. The following day Polish defenders withdrew from the town, but heavy casualties on both sides prevented the German units from continuing the attacks on the fortress. Instead, it was constantly shelled with artillery and bombed by the Luftwaffe. 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
