The Battle of Kock, was one of the first battles of the Invasion of Poland at the beginning of World War II. It took place from September 1 through September 27, 1939, near the town of Kock, Poland.

The Polish Independent Operational Group Polesie, led by General Franciszek Kleeberg, fought the German 14^th Motorised Corps, led by General Gustav von Wiedesheim.

[edit] Before the battle

The Polish battle plan was disorganized, but with few officers left this was expected. The Wehrmacht destroyed the Polish reserve Army Prusy and forced them to withdraw. With heavy losses, the Polish armies retreated to Kraków and the Vistula river. From there, they took the route from Warsaw to Sandomierz. From Sandomierz, they were able to move on to the Lublin area.

The eastern edge of the Vistula was defended by Lublin's weak army. The Polish forces camped only in the areas where they could cross the river easily, in case of an attack. Other German forces advanced on the Vistula and went on towards Zamość and Włodzimierz Wołyński.

The Polish Army at Kraków and Małopolska suffered heavy losses, and did not manage to reach the San river front. Therefore, they were unable to organize a proper defence. Field Marshal Rydz Śmigły was appointed to organize the defence of southern Poland. The commander of army area IX Brześć, General Franciszek Kleeberg, was appointed to organize the defence of the line from Pińsk to Brześć.

[edit] Group organisation

On September 8^th, General Franciszek Kleeberg received orders from Marshal Edward Rydz-Śmigły to organize a division of infantry from the depot division (a depot was where reserve soldiers and recruits were trained). Kleeberg was also ordered to organize a defensive line from Brześć to Pińsk. While his forces were well-trained, they lacked all heavy equipment as it had previously been dispatched to the front-line divisions.

[edit] Battle of Brześć and Kobryń

After breaking through the Polish lines in the Battle of Wizna, the German XIX Panzer Corps under Heinz Guderian started its fast advance southwards. The corps, composed of the 3^rd Panzer Division, 10^th Panzer Division, the 20^th Motorised Infantry Division and the reserve 2^nd Motorised Division, was ordered to capture the old fortress in Brześć Litewski and then strike further southwards towards Kowel and Galicia. The purpose of this attack was to cut Poland in two and paralyse the organisation of defences east of the Bug River.

Initially, the forces of Guderian advanced southwards almost unopposed. However, on September 14, they were stopped in the area of Brześć Fortress and Kobryń by a four-battalion-strong improvised force under general Konstanty Plisowski. In the three-day-long battle for the fortress (that became known as the Battle of Brześć), both sides suffered significant casualties. Although the Poles finally withdrew from the area on September 17, the Germans did not start the pursuit soon enough to rout the fleeing Poles. Also, the simultaneous attack on Kobryń, which is sometimes referred to as the Battle of Kobryń, was inconclusive, with the Polish improvised "Kobryń" Infantry Division under colonel Adam Epler withdrawing unopposed.

Both the Polish units from Kobryń and Brześć were soon joined by the Podlaska Cavalry Brigade. The unit, commanded by general Ludwik Kmicic-Skrzyński, successfully withdrew through Białowieża Forest and evaded encirclement. General Kmicic-Skrzyński, with his chief of staff major Julian Szychiewicz, went to Wołkowysk where he made phone contact with General Franciszek Kleeberg. The two agreed to join their forces and move southwards, towards the Romanian Bridgehead.

22 September After a battle with Red Army forces general Kleeberg decided to march to the relief of Warsaw. He planned first to capture crossing places on the Bug River. The place of concentration would be an area near Włodawa. Formations of the group fought only against the Germans. They could fight against the Red Army but only if Red Army formations tried to attack the group.

22–25 September Formations of group Polesie during march to Włodawa were attacked by German air forces. 25 September General Kleeberg got information that Włodawa was captured by unknown Polish formations. This formation were organized by Colonel Brzoza-Brzezina Most of soldiers are soldiers from destroyed Polish formations who weren't caught by Germans and were looking for commanders and formations which fought. Forces 5 battalions of infantry, two howitzer battery 75 mm, tabor, field hospital. scout squadron- 1 plane PSW two RWD-8. His forces began organising defence of bridgehead in Włodawa.

17–26 September Formations of Group Polesie crossed Bug river and entered area near Włodawa. 27 IX After getting information about surrender of Warsaw, General Kleeberg asked his commanders about their opinion. On first point he told about political and military situation, he asked General Podhorski commander of cavalry division "Zaza"- two brigade of cavalry "Plis", "Edward", two infantry battalions "Olek" and "Wilk", division artillery- that he should join his division to his forces. Podhorski agreed, after that they decided that at first they would go to Stawy near Dęblin- the location of the main arsenal of Polish army- and then go to the Holy Cross Mountains and engage in guerilla warfare.

Reorganization of independent group Polesie. One of the decisions of Kleeberg was new organisation of his group. He ordered that division Kobryń would get little supplies with people and weapons and would be named as 60^th Infantry Division. After joining groups "Brzoza" and "Drohiczyn" colonel Brzoza-Brzezina would organize 50th Infantry Division.

60^th Infantry Division- commander Colonel Adam Epler, forces- three infantry regiments, division of artillery, motorised company of anti-tank artillery 37 mm, seven independent under formations.

[edit] Battle of Kock

Commander of 10^th Army Walther von Reichenau ordered this task commander of XIV Motorised Corps. XIV- 29^th and 13^th Motorised Infantry Division and some independent formations. Each German motorised division had a paper strength 16445 soldiers, 2676 trucks and staff cars, 1944 motorcycles, and 18 armoured cars.

[edit] October 2^nd

The German commander of XIV Corp knew that Polish forces were situated in forests northwest from the town of Kock. He thought that the commander of Polish forces didn't know about capitulation of Warsaw.

In opinion of commander of 13^th Motorised Infantry Division General Paul Otto, the Polish forces had become so demoralized that they were incapable of combat, and that a German unit of one battalion would be enough to disarm the Poles and take them to a Prisoner of War camp.

Otto sent a force consisting of 3rd Battalion, 93^rd Motorized Infantry Regiment supported by 8^th Battery from 13^th Regiment of Light Artillery. The battalion commander decided to divide his forces into two groups which were sent to Serokomla and Kock. He could count on help from 93^rd Motorised Infantry Regiment with some support forces which followed him.

[edit] Kock

At 8:30 In the morning, a column of half-tracks and trucks with infantry was stopped by firing from a guard platoon of No.2 company of Battalion Wilk. After a long fight the German troops withdrew. The 179^th Infantry Regiment was alerted and moved to a defensive position near Kock and in town. At about 11:00 the German lead elements attacked the Polish positions, which were now 2 battalions strong. In spite of supporting artillery fire the attack failed.

About dusk German motorcyclists appeared near the church in Kock and begun firing, but subsequently withdrew under counter-fire.

[edit] Serokomla

A company of motorized infantry entered the village of Serokomla. This led to the beginning of a chaotic fight between the Germans and Polish Uhlans from Cavalry Brigade 'Plis' (commander Colonel Plisowski) supported by an artillery crew from the brigade of Plis. One side (which??) was forced to withdraw south of Serokomla.

[edit] Losses

German losses were 300–400 killed and wounded. 5 officers, 180 NCOs and privates were captured by the Polish. Components of Cavalry Brigade 'Plis' lost about 200 soldiers which were killed or wounded.

[edit] October 3^rd

The stiff Polish resistance forced General Otto to use all his forces for an assault. He was going to divide Polish forces into two parts and destroy them. He decided that 33^rd Motorised Infantry Regiment supported with a part of division artillery would attack on Annopol, Pieńki and Talczyn. This group was tasked to destroy 50 Polish Infantry Division. 93^rd Motorised Infantry Regiment was ordered to capture Serokomla then Hordzież and to destroy a defensive formation of cavalry division "Zaza". 66^th Motorised Infantry Regiment entered the field of battle in the afternoon.

General Kleeberg thought that main German advance would go on position of division of cavalry "Zaza" at Serokomla Hordzież. He decided that part of the cavalry would fend off the German attack. The rest would join a counterattack alongside 50^th Infantry Division on the right wing and rear of the 13^th German Motorized Infantry Division. 60^th Infantry Division and Cavalry Brigade 'Podlaska' brigade would close off potential German attack routes. If counter-attack would finish with success German division would be forced to withdraw behind river Wieprz.

7:50–9:30 Attack by two regiments of 50th Infantry Division (180th and 178th less its 2nd battalion) attacked supported with fire of a howitzer battery. The attack was under the command of Undercolonel Gorzkowski on German formations. After some success Polish counter-attack stopped. All Polish groups from 50^th Infantry Division were forced on the defensive. The cavalry attack by Uhlans was stopped and were forced to withdraw on west from Wola Gułowska.

10:30 German artillery begun fire on Polish cavalry position. 93^rd Motorized Infantry Regiment begun attack on position of battalion "Wilk", inflicting heavy losses. 33^rd Infantry Regiment began a gradual attack on the position of 50^th Infantry Division.

After heavy fight German advance was stopped. Otto decided to support 33^rd Motorised Infantry Regiment with 2^nd Battalion from 66^th Motorised Infantry Regiment. German formations captured Wola Gułowska, but in the evening they were forced to retreat from the eastern part of the area.

[edit] October 4^th

Because the 13^th Motorised Infantry Division had been unsuccessful, the commander of XIV Corp. was forced to use the 29^th Motorised Infantry Division. General Otto ordered the 93^rdInfantry Regiment to move from the Wieprz river to Dęblin. The 66^th Motorised Infantry Regiment would attack Adamów i Wola Gułowska, and the 33^rd Infantry Regiment would clear the area to the north of Kock.

General Kleberg suspected that the main combined attack of the 13th Motorised Division and the 29^thMotorised Division would be on Adamów and Krzywda. He thought there was a chance to destroy the 13^thMotorised Division as they had already sustained heavy casualties with soldiers and materiel loss. The cavalry division "Zaza" and 50^thInfantry Division would defend positions and the 60^thInfantry Division would attack the 13^th Motorised Division. The Podlaska Cavalry Brigade would oppose the 29^thMotorised Infantry Division.

In the morning, the main elements of 13^thDivision attacked the cavalry division Zaza and the 50^thInfantry division. By 12:00 part of 66^thInfantry Regiment captured Zakępie and advanced on Adamów where they were stopped by 1st Battalion of 180^th Infantry Regiment.

About 11 hours apart, first from the west and then the east, forces from the 66^th Regiment attacked the battalions Olek and Wilk defending Czarna. The defenders sustained heavy casualties from artillery fire and Wilk was forced to withdraw to the eastern edge of the Adamów forest whereas Olek, after first retreating to Adamów later deployed to Gułów. Between 10:00 and 11:00 formations of 66^th Regiment attacked formations of cavalry from the 5^th Uhlans Regiment who then withdrew from Wola Gułowska to the south east and Adamów.

About 12:00 the 66^ththen attacked the 2^ndSquadron of the 2^ndUhlans Regiment in Zarzecze who also withdrew with heavy casualties. The commander of the regiment moved the 4^thSquadron south from Helenowka to try to assist the 2^nd Squadron while the 3^rdSquadron held the enemy to the west of Wola Gułowska. Then the 3^rd and 4^th Squadrons with elements of the 10^th Uhlans Regiment fought near the cemetery of the village of Turzyca B and the church in Wola Gułowska. Ground was lost and regained repeatedly until an attack of 2^ndBattalion 184^thInfantry Regiment and the Uhlans Squadron enabled the Polish to dig in.

[edit] October 5^th

The commander of XIVth Motorized Corp. decided that he would use two of his divisions. They would attempt to encircle and destroy the Polish forces. The 13^th Motorized Division advanced on Bystrzyca and Adamów then Wróblina and Stanin; the 29^th Motorised Division advanced on Radyryż Kościelny and Wróblina where they met troops from 13^th Division.

General Kleeberg decided to destroy 13^th Motorised Infantry Division by using the forces of 50^th, 60^th infantry division and the Zaza Cavalry division. The Podlaska Cavalry Brigade defended the position under Radoryż Kościelny and Wróblina.

General Podhorski sent the cavalry brigade "Plis" which had to support fighting Polish formations. The brigade had to take position on the eastern edge of the forest at Adamów. After contact with enemy brigade, they began an attack on the Germans' position in the forest. They captured the forest and then because they couldn't move, they established defensive positions there.

After the capture of Adamów and grange Gułów by the 66^th Infantry Regiment, the 33^rd Motorised Infantry Regiment began to advance, and captured Wojcieszkowoe and Glinne. Polish formation 178^th Infantry regiment withdrew. The commander of 178^th Infantry Regiment ordered his force to recapture Wojcieszkowo and Glinne.
