Kraków Army
Kraków Army was one of the Polish armies which took part in the Polish Defensive War of 1939. It was officially created on March 23, 1939 as the main pivot of Polish defence. It was commanded by Gen. Antoni Szylling. Originally, Kraków Army was to be made of seven infantry divisions, two cavalry brigades and one mountain brigade. On September 1, 1939, General Szylling had the force which consisted of five infantry divisions, two cavalry brigades and one brigade of mountain infantry. Altogether, the army was made of 59 battalions, 29 squadrons, 352 cannons, 90 tanks, two armoured trains and 44 planes. These forces were not enough to halt German advance, especially in the area north of Częstochowa, where Kraków Army connected with Łódź Army. Main thrust of Wehrmacht panzer units was directed there, and this area was defended only by the Polish 7th I.D., which was destroyed in the early days of September 1939, opening the way towards central Poland.
Creation of Kraków Army
On March 15, 1939, units of the Wehrmacht entered Prague, and two days earlier at Berlin, Joachim von Ribbentrop in a conversation with Polish ambassador Józef Lipski demanded definite answer to German demands of Free City of Danzig and a highway through the Polish Corridor. On March 23, a number of officers of the Polish Army was ordered to come to the General Inspector of the Armed Forces in Warsaw. Together with General Antoni Szylling, these officers were ordered to create staff of the newly created Kraków Army. The army itself was created upon written order of Edward Rydz-Śmigły, which was handed to General Szylling on the same day, together with more detailed demands. On March 25, staff officers of Kraków Army arrived at Kraków, staying at the Jan III Sobieski barracks, where the 5th Military Police Unit was located. On the same day at noon, General Szylling met commanders of the divisions that came under his control, and on March 27, the officers took their oath.Tasks
Its main task was to delay advancing German troops and withdraw eastwards along the northern line of the Carpathians and defend the heavily industrialized Upper Silesia region, together with western counties of Lesser Poland and the Carpathian foothills. Altogether, Kraków Army defended southwestern border of Poland, from Krzepice near Częstochowa, to Czorsztyn. In the area of Częstochowa, the 7th I.D. was placed, with its right wing supported by the Kraków Cavalry Brigade of General Zygmunt Piasecki. The remaining units were divided into two operational groups. Operational Group Silesia was made of the 23rd I.D., together with the 55th I.D., and soldiers manning the Fortified Area of Silesia. Operational Group Bielsko was made of the 21st I.D., and the 1st Brigade of Mountain Infantry. This group was located in the area of Żywiec, Chabówka, and Bielsko-Biała. Furthermore, in the area of Pszczyna was the 6th I.D., and in the area of Kraków, the 10th Motorized Cavalry Brigade.Kraków Army's tasks were as follows:
- to defend Upper Silesia,
- to protect the general direction towards the city of Kraków from southwest,
- to defend the strategic rail line from Dąbrowa Górnicza Ząbkowice to Częstochowa,
- final line of defence was as follows: Fortified Area of Silesia - Mikołów - Pszczyna - Bielsko-Biała - Żywiec.
Operational history
Battle of the Border
Kraków Army fought against German Army Group South, whose units crossed the border on September 1, 1939, at 4 a.m. In central part of the front, German 10th Army advanced, attacking in the sector from Tarnowskie Góry to Wieluń. North of the 10th Army was the 8th Army, and in the south was and the 14th Army, advancing towards Kraków. On September 1, the Wehrmacht failed to cause a breach Polish positions, but it was obvious that the Germans tried to bypass Fortified Area of Silesia, attacking both north and south of the fortifications. As early as the night of September 1/2, Polish situation became difficult, as the 7th I.D., operating near Częstochowa, found it hard to halt the advance of the panzers of the XVI Panzer Corps, which fought their way into central Poland. This division was located some 40 kilometers away from other Polish units; close to it was the Volhynian Cavalry Brigade, which itself was attacked by the Germans in the Battle of Mokra.On September 2, German 1st Panzer Division bypassed Częstochowa north of the city, and supported by the Luftwaffe, managed to cross the Warta river. At the same time, Kraków Cavalry Brigade was attacked by the 2nd Light Division in the area of Woźniki. After heavy fighting, it withdrew towards Zawiercie, which caused a breach in the defensive line, enabling the Germans both to bypass Polish fortifications in Upper Silesia, and to attack the 7th I.D. from the rear. As a result, the 7th I.D. was destroyed on Sept. 2, and its remaining units retreated to the forests near Koniecpol. This defeat enabled German XVI Panzer Corps to move towards Kielce without any problems. Since Polish Army did not have any reserve units east of Częstochowa, Edward Śmigły-Rydz ordered a detachment of the PZL.23 Karaś bombers to attack the advancing panzers. The attack, however, did not result in a success, and the advance of the Wehrmacht continued.
In the south, the Wehrmacht attacked on Sept. 2 in two spots - Mikołów/Pszczyna, and Wysoka/Rabka. Near Pszczyna, Polish 6th I.D. failed to halt the 5th Panzer Division, and in the morning of the same day, the 2nd Panzer Division was stopped in the Battle of Jordanów. At the same time, however, the Germans won the Battle of Węgierska Górka. In the afternoon of September 2, the situation of Kraków Army turned critical. German panzers attacked in large formations in the area of Koziegłowy in the north, and in the area of Jordanów in the south. Furthermore, breach of the Polish lines near Pszczyna caused another problem, as it gave the Germans an opportunity to bypass the Upper Silesian fortifications. As a result, General Szylling, in a conversation with Marshall Śmigły-Rydz stated that it was necessary to withdraw from Upper Silesia and Zaolzie, and to retreat towards Kraków. The Marshall gave tentative permission at 16:00 on Sept. 2, urging Szylling to press his soldiers to do their best. In the evening of September 2, the situation deteriorated further, as Kraków Cavalry Brigade was pushed behind the Warta, and the distance to the retreating remnants of the 7th I.D. was some 30 kilometres. German 2nd Light Division entered this gap, advancing towards Żarki. The Luftwaffe bombed Polish towns and rail junctions, General Szylling was unable to locate the positions of his divisions, and to get in touch with their commandants. At 18:00, Szylling once again talked with Śmigły-Rydz, and 30 minutes later, the Marshall agreed to the withdrawal of Kraków Army to the line marked by the Nida and Dunajec rivers. It was a difficult decision, as it meant that the pre-war Polish defensive plan was abandoned. Śmigły-Rydz, however, hoped that the retreat would save Kraków Army from complete destruction.
The Retreat
In the evening of Saturday, Sept. 2, the order to retreat reached Polish units. Kraków Cavalry Brigade, together with the 7th I.D. was to move towards Jędrzejów, halting the advance of the 2nd Light Division. 22nd Mountain I.D. was to withdraw towards Olkusz, and to support Operational Group Silesia, which itself was to retreat behind the Przemsza. Operational Group Bielsko was to withdraw behind the Skawa, and to take positions between Zator and Wadowice. General retreat towards the Dunajec and the Nida was to begin in the night of September 2/3.. General Szylling specified that units located in the centre of the front were to retreat first, to avoid being surrounded by German panzers advancing fast both in the north and the south. This plan failed, as Polish 7th I.D. was completely destroyed in the morning of Sunday, September 3, by the 14th Infantry Division, the 4th Infantry Division, and the 2nd Light Division.The retreat itself did not improve the situation of Kraków Army, as it lost its fortified defensive positions, together with heavy equipment, which was abandoned. Polish historians Czesław Grzelak and Henryk Stańczyk in their book "Kampania polska 1939 roku" write that several historians question the decision of General Szylling, as in their opinion the decision to withdraw eastwards on the second day of the war was premature. Tadeusz Jurga wrote: "To remain in defensive positions would result in halting the advance of the German 10th Army, which later destroyed Prusy Army Furthermore, defensive positions of Kraków Army were based on fortifications, which had been built before the war. These fortifications eliminated technological superiority of the Wehrmacht. To abandon them and to fight in the open lowered defensive abilities of Kraków Army".
The decision to abandon southwestern Poland had far-reaching consequences, as Kraków Army was the centre point of the defensive plan. Its new line of defence along the Dunajec and the Nida was ill-prepared, and the retreat itself turned out to be very difficult, as Polish units were under constant pressure of the Luftwaffe and German motorized divisions. In the morning of September 3, General Szylling ordered general retreat east of Kraków, dividing his army into Operational Group Jagmin, and Operational Group Boruta. Szylling hoped to reach the defensive line by September 7, and first days of retreat were relatively calm, as the Wehrmacht concentrated its efforts in the area of Piotrków Trybunalski.
The End of Kraków Army
On September 5, German 2nd Panzer Division, together with the 3rd Mountain Division and the 7th Infantry Division broke through Polish lines near Pcim, capturing Myślenice, Bochnia and Wiśnicz, thus positioning themselves in the rear of the retreating units of Operational Group Boruta. On the same day, Fall 5 September instruction was issued by the Oberkommando der Wehrmacht, ordering German divisions to continue their advance towards Tarnów and Rzeszów. On September 6, German 4th Light Division attacked Polish 24th I.D. near Tarnów, crossing the Dunajec south of Zakliczyn. Polish unit managed to halt the Germans, and its commandant, Colonel Bolesław Krzyżanowski hoped to keep the line of the Dunajec for Operational Group Boruta. In the evening of September 6, General Kazimierz Fabrycy ordered him to retreat to the Wisłoka river. On the same day, Polish units abandoned Kraków.On September 6, Marshall Śmigły-Rydz reorganized the units fighting in southern Lesser Poland. Operational Group Boruta was moved to Karpaty Army, and soon afterwards, Karpaty Army was merged with Operational Group Jagmin, creating Małopolska Army, under General Fabrycy. Śmigły-Rydz was well aware of the fact that it was impossible to hold the line of the Dunajec and the Nida, and that further retreat towards the San was the only option.
