three separate assault groups. The 1st Panzer Division headed directly towards the town of Kłobuck, held by the Polish 7th Infantry Division, while the 4th Panzer Division was split into northern and southern columns, each trying to outflank the Polish positions around Mokra. At the same time, the Luftwaffe began a heavy bombardment of the Polish positions. By the end of the day, German aircraft made 15 attacks, with 9 to 26 bombers in each. The planes were mostly Junkers Ju 87 dive bombers. At 0630 in the morning the motorcycle reconnaissance squads of the 4th Panzer Division made contact with the 12th company of the 84th Infantry Regiment under Stanisław Radajewicz. Soon afterwards the AFVs arrived, supported by infantry and purportedly using Polish civilians as human shields. However, after several hits from Polish AT weapons on their flanks, the German tanks lost orientation, which allowed the civilians to cross the Polish lines with negligible losses. The German assault was renewed shortly afterwards, but was repelled by heavy machine gun fire. Two AFVs retreated, while the majority of the motorcyclists were taken prisoner. The 4th Panzer Division then mounted an assault on the Polish 21st Uhlans Regiment, further northwards. After a short artillery barrage and aerial bombardment, the German tanks took the village of Wilkowieck and headed directly for the village of Mokra. However, although the regiment lost many horses and approximately five ammunition cars, the bombs mostly missed the Polish defensive positions and the advancing tanks were welcomed at 150 metres by well-positioned Polish-made 37mm Bofors antitank guns. After two Panzers were destroyed, the German tanks withdrew to 400 metres and started shelling the Poles with artillery, but after losing two additional AFVs (one destroyed and one immobilized), the German tanks retreated. The German infantry were left on a flat open field, right in front of the Polish positions, without any cover. They were forced to retreat by a Polish cavalry attack that caused heavy losses and resulted in a number of prisoners being taken by the Poles. The positions of the 19th Uhlans Regiment were attacked at 0800 by an assault group composed of tanks, AFVs, motorcyclists and infantry. The German group, divided into three columns, was advancing towards the village of Rębielice Szlacheckie in order to outflank the 21st Regiment from the north. However, the Germans were apparently unaware of the 19th Regiment's positions. The westernmost group
