Mokra - September 1, 1939

Mokra


Mokra is a village in southern Poland. In 1939 it was close to the Polish-German border and it was situated on the main approach route towards Warsaw from the southwest. The German OKH conceived a double envelopment of the Polish Army which was to be carried by two strong Army Groups that were to trap the Polish armies in western Poland. In this pincer movement the southern arm was to be launched from the Silesian-Polish border northeastward and was to join the northern arm east of Warsaw. The German Tenth Army was to carry the main thrust. It struck out in the direction of Warsaw with the largest concentration of armor. Tenth Army’s strongest element was Erich Hoepner’s XVI Armeekorps (mot.).

The Battle

Mokra battle 06:30 – 08:30 hrs

06:30 – 08:30 hrs. Motorcycle squads made contact with 4/84 Infantry Battalion in the south and the 19th Uhlans in the north. A force of 25 tanks of 36th Panzer-Regiment advanced as far as Wilkowiecko, but was repulsed by antitank fire from 37mm A/T guns.

Mokra battle 10:00-11:00 hrs

10:00 – 11:00 hrs. In the north the 19th Uhlans withdrew to a wooded area, pressed by German tanks. The 12th Uhlans were sent to reinforce them. The Germans outflanked the 19th Uhlans and forced them to retreat behind the railway line. In the center the 36th Panzer-Regiment tried to penetrate into Mokra and mounted an attack with tanks only. The attack was broken up by artillery fire and fire from “Smialy”. Later on the attack was renewed with infantry support but fared no better. Part of the 12th Uhlans was sent to reinforce the positions of the 21st Uhlans. In the south the 4/84 Inf. Btn. was attacked by German infantry and withdrew. The Brigade Commander ordered the 2nd Mounted Rifle Regiment to counterattack.

Mokra battle 12:00-16:00 hrs

12:00-16:00 hrs. The 36th Panzer-Regiment launched a full scale attack and reached the village of Mokra. The 21st Uhlans retreated to the railway line. As the German tanks were advancing further they received direct fire from the 2nd Mounted Artillery Battalion, and many were lost. The German force withdrew and repeated its attack at 15:00 hrs. The situation turned critical for the Poles, although they had destroyed many enemy tanks. The 2nd Mounted Rifle Regiment and the 21st Armored Battalion were ordered to counterattack. In the north the position of the 19th Uhlans was endangered when German tanks started crossing the railway line at Izbiska, but the timely arrival of “Smialy” repulsed them. “Smially” was hit by Stukas but was not destroyed. After receiving heavy tank losses the 4th Panzer-Division withdrew to its jump off positions at Wilkowiecko. Only 12. Infanterie-Regiment (mot.) remained close to the railway line. To the south of the 4th Panzer the 1st Panzer-Division took Klobuck and outflanked the Mokra position. Cavalry Brigade “Wołyńska” withdrew during the night.

Conclusions

In this early stage of the war there were signs of nervousness, confusion and poor coordination with the accompanying infantry amongst the panzer divisions. Panzer-Division “Kempf”, of Army Group North, also failed in its first attack. There was no previous experience of massed tank operations and the new ideas needed some time to mature. However, such initial shortcomings were quickly overcome and the panzer divisions played the decisive role in the Campaign.
