retreated with heavy losses, losing a number of Panzer I and II tanks, while the 19th Regiment crossed the railroad under cover of the armoured train. Although the 19th Regiment suffered heavy losses, it managed to regroup on the other side. Simultaneously, a German attack on the main positions of the 21st Regiment near the village of Mokra began. German tanks managed to outflank the 4th Squadron of the Regiment from the north, at the same time attacking it frontally. The Polish defenders were pushed out of the forest and heavy fighting for the village itself started. The Germans lost four tanks to the Polish 2nd Artillery Battalion firing from across the railway, but the 4th Squadron was in retreat, fighting for almost every house in the village and suffering heavy losses. Again the day was saved by Śmiały. It arrived in the area at the height of the battle and opened fire from a distance of almost 2.5 km, which was beyond the effective range of all German tank guns of the time, in the end destroying or knocking out several more Panzer I and IIs. Also, more Polish cavalry, made up of the 12th Uhlans Regiment, was moved to the area; the men dismounted and reinforced the 21st Regiment. Polish counter-attack and the "Charge" The 21st Armoured Battalion under Maj. Stanisław Gliński, equipped mostly with Polish TKS tankettes was ordered to counter-attack the village, along with the cavalry squadron of Captain Jerzy Hollak. In the clouds of smoke of the burning village, the Polish units accidentally drove right into the middle of a German tank column. Although the Polish tankettes were no match for the heavier Panzer II German tanks and the cavalry was very vulnerable to tank fire, the confusion in German ranks prevented their commander from responding quickly enough. The Polish units managed to break through the German column with negligible losses and seized the forest to the northwest of Mokra. This manoeuvre is sometimes referred to as a Polish cavalry charge against German tanks, although no charge was planned nor executed. Nevertheless, the German tanks again lost orientation and the column withdrew from the village, again leaving it in Polish hands. The tanks withdrew to their initial positions in Wilkowiecko, leaving behind the infantry supporting the failed assault. German losses were high and a large number of German troops were taken prisoner. At the same
