The Prusy Army ( Polish : Armia Prusy ) was one of the Polish armies to fight during the Invasion of Poland in 1939. Created in the summer of 1939 as the main reserve of the Commander in Chief, it was commanded by Gen. Stefan Dąb-Biernacki . The word Prusy in the Polish language means Prussia , but this name only served as a codename and the region of operations of this army was far from East Prussia . This is in contrast to other Polish armies in 1939 which were named after the geographical regions where they formed. The Prusy Army, whose original name was Warszawa Army, was named so after a folwark in central Poland called Prusy, which served as the headquarters of General Dąb-Biernacki.
27-474: According to the "Plan West" ( Plan Zachód , the code name for the Polish mobilization plan) it was to be composed of units mobilized as the second and third waves, and its main purpose was to cooperate with the nearby armies " Łódź " and " Kraków ". It was being mobilized in two groups after the outbreak of hostilities. It consisted of 6 infantry divisions, 1 cavalry brigade and a battalion of tanks. Once ready, it
54-611: A city disputed between Poland and Lithuania, and a small Polish force, primarily elite units of Border Defence Corps , was detached to secure that region. The plan assumed that Polish forces would be able to hold for several months but would be pushed back by the German numerical and technical superiority, which was estimated to be two or three to one. Then, the Western Allies (France and the United Kingdom), obliged by
81-545: A possible deep, flanking, eastward push from Prussia and Slovakia , but that push was assigned high priority in the German plan ( Fall Weiss ). A controversy involved the decision whether Polish forces should defend the lengthy borders or should withdraw east and south and try to defend a shorter line, backed with rivers. Although the second plan was more militarily sound, political considerations outweighed them, as Polish politicians were concerned that Germany could be satisfied with occupation of some disputed territories (like
108-579: The 10th Motorized Cavalry Brigade belonged to the Prusy Army. In late July 1939, Marshall Śmigły-Rydz decided to move this unit to Kraków Army . The northern group, seriously damaged in the battles of Piotrków and Tomaszów Mazowiecki (September 5 - September 6) was forced to cross the Vistula. The southern group, much less organized and poorly commanded, fought in the Battle of Iłża , after which it

The plan correctly assumed the size, location and most of the directions of attack by the enemy. When the Germans attacked, however, the second and further defensive lines and related items were not fully defined by

The western regions were also the most densely populated ones and had major industrial centres, which were crucial for mobilization and any continued military production of equipment and supply for the Polish Army. Even with the decision to protect

Skwarczynski was born on 17 November 1888 in the village of Wierzchnia , Kalusz County, Austrian Galicia . He studied architecture at Lwow Polytechnic , and was an active member of Polish paramilitary organizations, such as the Union of Active Struggle and the Riflemen's Association . In 1914, he joined Polish Legions in World War I . Appointed to

After German annexation of parts of Czechoslovakia and changes of borders, Polish planners revised the plan with the expectation that a main thrust would originate from Silesia through Piotrków and Łódź towards Warsaw and Kraków . The Polish planners correctly predicted the direction of most German thrusts, with one crucial exception: they assigned low priority to
243-676: The Soviet invasion of Poland and lack of promised aid from the Western Allies , contributed to the Polish defeat by 6 October 1939. Stanis%C5%82aw Skwarczy%C5%84ski Stanisław Eugeniusz Skwarczyński (1888–1981) was a soldier of the Austro-Hungarian Army , officer of Polish Legions in World War I , and General brygady of the Polish Army .

270-697: The Wehrmacht in the Battle of Radom , after which he ordered 12th Infantry Division to disperse and abandon its heavy equipment, including 50 cannons. Together with a number of soldiers, he managed to cross the Vistula , and join the units which moved southwards, to the Romanian Bridgehead . Captured by the Germans during the Battle of Tomaszow Lubelski , he was sent to Oflag Dorsten , where he remained until liberation. In April 1945, he went to London , and remained in exile until his death. After

Plan Zach%C3%B3d Plan West ( Polish : Plan Zachód ) was a military plan of the Polish Army of the Second Polish Republic , for defence against invasion from Nazi Germany . It was designed in the late 1930s. While Józef Piłsudski was the dictator of Poland, planning concentrated on a possible attack on Poland from

#1732794458402324-448: The armies "Łódź" and "Krakow," but they failed to predict the fast pace of the German advance. Therefore, in Polish plans "Armia Prusy" was to be fully mobilized only by 14 September 1939, while in reality, it needed to be ready as soon as the late night of 3 September 1939. As Polish historians Czesław Grzelak and Henryk Stańczyk wrote: "Polish planners miscalculated the speed of the advance of German panzer and motorized units, and plans for
351-470: The borders, the fact that Poland was virtually encircled from three sides by the Germans caused the decision that some areas were almost impossible to defend and so had to be abandoned early on. That was the case for the northwestern Pomorze Voivodeship and Poznań Voivodeship . A separate force, the Land Coastal Defence , was to protect key parts of the coast as long as possible, and most of
378-478: The conflict were based on the experiences of the First World War". The Poles were surprised by how fast they would have to fall back to prevent the destruction of their units. This miscalculation led to the capture of the city of Łódź - a major setback to the Polish plan of defending the country west from the Vistula river at least until October 1939. More surprising should be that the "Polish schedule"
405-669: The east. It was only after Piłsudski's death in 1935 that the new Polish government and military re-evaluated the situation and decided that the current Polish plan for a Polish–German war, dating from the mid-1920s (Plan "S"), was inadequate and needed to be revised. However up to 1938, the priority remained in the east, not the west, and most Polish fortifications were being erected on the Polish–Soviet border. The first version predicted that Germans would attack from Pomerania towards Warsaw , with supporting thrusts from Silesia and Prussia , aiming at establishing an early link through
432-523: The plan, and none of its aspects had been subject to a military exercise. There were also other unfinished parts, particularly those dealing with communications and supplies. When Germany invaded Poland on 1 September 1939, Polish forces were dealt a significant defeat at the Battle of the Border , just as critics of the plan had predicted. Further factors, such as underestimating German mobility and blitzkrieg strategy and overestimating Polish mobility,

After the Oath crisis , Skwarczynski was forced to join Austro-Hungarian Army, from which he deserted. In 1918 – 1917, he was conspirational commandant of Łódź Area of Polish Military Organisation . In November 1918, Skwarczynski joined Polish Army, and soon afterwards, he became commandant of 3rd Battalion of 28th Kaniow Rifles Regiment. Together with his unit, he briefly fought against Czechoslovak forces in Cieszyn Silesia , to be transferred to Eastern Galicia, where Polish-Ukrainian conflict took place in late 1918 and 1919. On 15 April 1920 Skwarczynski
486-407: The southern group was to support Kraków Army by preparing the defence of central Vistula river area. Because of fast German advance both groups entered combat separately and most units did not reach full mobilization. Due to the deteriorating situation in the battle of the border , it was decided to push partially mobilized units of Prusy Army to the front as soon as possible. In original Polish plans,
513-885: The surface Polish Navy was to be evacuated to the United Kingdom as specified in the Peking Plan ( submarines were to engage the enemy in the Baltic Sea , according to the Worek Plan ). The main Polish defence line was to be formed on the regions of the Augustów Primeval Forest – Biebrza River – Narew River – Vistula River (and the towns of Modlin , Toruń , Bydgoszcz ) – Inowrocław Lakes – Warta River – Widawka River – town of Częstochowa – Silesian fortifications – town of Bielsko-Biała – town of Żywiec – village of Chabówka – and
540-688: The town of Nowy Sącz ). The second defensive line was based on the Augustów Forest - Biebrza River – Narew River – Bug River – Vistula River – and Dunajec River. Finally, the third defensive line involved retreating southeast towards the Romanian border and holding as long as possible in the region of the Romanian Bridgehead . The plan assumed the Soviet Union would be neutral, as a German–Soviet alliance seemed unlikely. The plan, however, allowed for Lithuania to try to take Wilno ,
