82-662: The voivodeship was dissolved on 8 October 1939 following the German invasion of Poland , and its territory was incorporated into the German Province of Silesia. After the defeat of Nazi Germany in World War ;II, its territory was incorporated into a new, larger Silesian Voivodeship which existed until 1950. The Silesian Voivodeship was one of the richest and best developed provinces of inter-war Poland . It owed its wealth to rich deposits of coal , which resulted in

164-639: A military alliance with the United Kingdom and with France , believing that Polish independence and territorial integrity would be defended with their support if it were to be threatened by Germany. On the other hand, British Prime Minister Neville Chamberlain and his Foreign Secretary , Lord Halifax , still hoped to strike a deal with Hitler regarding Danzig (and possibly the Polish Corridor). Chamberlain and his supporters believed war could be avoided and hoped Germany would agree to leave

246-536: A "last minute" order in the summer of 1939, Poland bought 160 French Morane-Saulnier M.S.406 fighters and 111 English airplanes (100 light bombers Fairey Battle , 10 Hurricanes and 1 Supermarine Spitfire ; the sale of 150 Spitfires asked by the Polish government was rejected by the Air Ministry). Despite the fact that some of the airplanes had been shipped to Poland (the first transport of purchased aircraft on

328-531: A 'Bomber Brigade', 'Pursuit Brigade' and aircraft assigned to the various ground armies. The Polish fighters were older than their German counterparts; the PZL P.11 fighter—produced in the early 1930s—had a top speed of only 365 km/h (227 mph), far less than German bombers. To compensate, the pilots relied on its maneuverability and high diving speed. The Polish Air Force's decisions to strengthen its resources came too late, mostly due to budget limitations. As

410-574: A German sabotage group which had not heard anything about a delay of the invasion made an attack on the Jablunkov Pass and Mosty railway station in Silesia . On the morning of 26 August, this group was repelled by Polish troops. The German side described all this as an incident "caused by an insane individual" (see Jabłonków incident ). On 26 August, Hitler tried to dissuade the British and

492-527: A Polish majority and had been disputed between Czechoslovakia and Poland in the aftermath of World War I. The Polish annexation of Slovak territory (several villages in the regions of Čadca , Orava and Spiš ) later served as the justification for the Slovak state to join the German invasion. By 1937, Germany began to increase its demands for Danzig, while proposing that an extraterritorial roadway, part of

574-561: A great power, prove that the Poles no longer are willing to respect the German frontier." Poland participated with Germany in the partition of Czechoslovakia that followed the Munich Agreement , although they were not part of the agreement. It coerced Czechoslovakia to surrender the region of Český Těšín by issuing an ultimatum to that effect on 30 September 1938, which was accepted by Czechoslovakia on 1 October. This region had

656-517: A part of Poland after the Treaty of Versailles . Many Germans also wanted the urban port city of Danzig and its environs (comprising the Free City of Danzig) to be reincorporated into Germany. Danzig city had a German majority, and had been separated from Germany after Versailles and made into the nominally independent Free City. Hitler sought to use this as casus belli , a reason for war, reverse

738-401: A quarter of the total whole population of the region. The Treaty of Versailles resolved that a plebiscite be conducted so that the local population could decide whether Upper Silesia should be assigned to Poland or to Germany . Before the plebiscite took place, two Silesian Uprisings supporting the Polish option had broken out. A third uprising occurred after the plebiscite. Based on

820-540: A week before the onset of war, Hitler delivered a speech to his military commanders at the Obersalzberg : The object of the war is … physically to destroy the enemy. That is why I have prepared, for the moment only in the East, my 'Death's Head' formations with orders to kill without pity or mercy all men, women, and children of Polish descent or language. Only in this way can we obtain the living space we need. With

902-725: The German–Polish Non-Aggression Pact of 1934. Earlier, Hitler's foreign policy worked to weaken ties between Poland and France and attempted to manoeuvre Poland into the Anti-Comintern Pact , forming a cooperative front against the Soviet Union . Poland would be granted territory to its northeast in Ukraine and Belarus if it agreed to wage war against the Soviet Union, but the concessions

984-752: The Gleiwitz incident . Slovak military forces advanced alongside the Germans in northern Slovakia . As the Wehrmacht advanced, Polish forces withdrew from their forward bases of operation close to the Germany–Poland border to more established defense lines to the east. After the mid-September Polish defeat in the Battle of the Bzura , the Germans gained an undisputed advantage. Polish forces then withdrew to

1066-790: The Polish Underground State within the territory of the former Polish state. Many of the military exiles who escaped Poland joined the Polish Armed Forces in the West , an armed force loyal to the Polish government-in-exile . On 30 January 1933, the National Socialist German Workers' Party , under its leader Adolf Hitler , came to power in Germany . While some dissident elements within

1148-700: The Reichsautobahn system, be built in order to connect East Prussia with Germany proper , running through the Polish Corridor. Poland rejected this proposal, fearing that after accepting these demands, it would become increasingly subject to the will of Germany and eventually lose its independence as the Czechs had. Polish leaders also distrusted Hitler. The British were also wary of Germany's increasing strength and assertiveness threatening its balance of power strategy. On 31 March 1939, Poland formed

1230-606: The Romanian Bridgehead could be created. The Polish General Staff had not begun elaborating the "West" defence plan until 4 March 1939. It was assumed that the Polish Army, fighting in the initial phase of the war alone, would have to defend the western regions of the country. The plan of operations took into account the numerical and material superiority of the enemy and, also assumed the defensive character of Polish operations. The Polish intentions were defending

1312-654: The September Campaign , Polish Campaign , and Polish Defensive War of 1939 (1 September – 6 October 1939), was a joint attack on the Republic of Poland by Nazi Germany , the Slovak Republic , and the Soviet Union , which marked the beginning of World War II . The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and

1394-568: The Weimar Republic had long sought to annex territories belonging to Poland, it was Hitler's own idea and not a realization of any pre-1933 Weimar plans to invade and partition Poland, annex Bohemia and Austria, and create satellite or puppet states economically subordinate to Germany. As part of this long-term policy, Hitler at first pursued a policy of rapprochement with Poland, trying to improve opinion in Germany, culminating in

1476-475: The 1,009 cars and trucks and 4,842 horses in the average German infantry division, the average Polish infantry division had 76 cars and trucks and 6,939 horses. The Polish Air Force ( Lotnictwo Wojskowe ) was at a severe disadvantage against the German Luftwaffe due to inferiority in numbers and the obsolescence of its fighter planes. However, contrary to German propaganda, it was not destroyed on

1558-605: The 1931 population census). a. In 1934, the town of Królewska Huta , the village of Maciejkowice , the commune of Nowe Hajduki and the village of Chorzów Stary were merged, creating the city of Chorzów . Additionally, on April 1, 1939, the commune of Wielkie Hajduki also became incorporated into the city of Chorzów.

The September Campaign was devised by General Franz Halder , the chief of the general staff , and directed by General Walther von Brauchitsch the commander in chief of the German ground forces . It called for the start of hostilities before a declaration of war , and pursued a doctrine of mass encirclement and destruction of enemy forces. The infantry, far from completely mechanized but fitted with fast-moving artillery and logistic support,

1722-458: The Corridor broke down, and months passed without diplomatic interaction between Germany and Poland. During this interim period, the Germans learned that France and Britain had failed to secure an alliance with the Soviet Union against Germany, and that the Soviet Union was interested in an alliance with Germany against Poland. Hitler had already issued orders to prepare for a possible "solution of

1804-575: The French from interfering in the upcoming conflict, even pledging that the Wehrmacht forces would be made available to Britain's empire in the future. The negotiations convinced Hitler that there was little chance the Western Allies would declare war on Germany, and even if they did, because of the lack of "territorial guarantees" to Poland, they would be willing to negotiate a compromise favourable to Germany after its conquest of Poland. Meanwhile,

1886-634: The German Province of Upper Silesia . The territory returned to Polish possession at the end of the war, and the 1920 act giving autonomous powers to the Silesian Voivodeship was formally repealed by a law of 6 May 1945. An enlarged Silesian Voivodeship (unofficially called Silesia- Dąbrowa Voivodeship, województwo śląsko-dąbrowskie ) continued in existence until 1950, when it was divided into Katowice Voivodeship and Opole Voivodeship . (For details, see Administrative division of

1968-428: The German puppet state of Slovakia meant that Poland's southern flank was also exposed. Hitler demanded that Poland be conquered in six weeks, but German planners thought that it would require three months. They intended to exploit their long border fully with the great enveloping manoeuver of Fall Weiss . German units were to invade Poland from three directions: All three assaults were to converge on Warsaw , and

2050-558: The Germans had seven Panzer divisions, with 2,009 tanks between them, using a new operational doctrine . It held that these divisions should act in coordination with other elements of the military, punching holes in the enemy line and isolating selected units, which would be encircled and destroyed. This would be followed up by less-mobile mechanized infantry and foot soldiers. The Luftwaffe (air force) provided both tactical and strategic air power , particularly dive bombers that disrupted lines of supply and communications. Together,

2132-557: The Germans, and these units, dispersed within the infantry, were unable to effectively engage the Germans. Experiences in the Polish–Soviet War shaped Polish Army organizational and operational doctrine. Unlike the trench warfare of World War I, the Polish–Soviet War was a conflict in which the cavalry 's mobility played a decisive role. Poland acknowledged the benefits of mobility but was unable to invest heavily in many of

2214-617: The People's Republic of Poland .) The voivodeship possessed wide autonomy in domestic matters excluding foreign and military policy. It had its own Silesian Parliament with 48 MPs (24 since 1935) elected in democratic elections. Legislation, however, had to be consistent with the Polish constitution. The voivodeship also had its own national treasury - the Silesian Treasury ( Polish : Skarb Śląski ). Only around 10% of taxes were transferred to Polish national treasury. The head of

2296-450: The Poles were expected to make meant that their homeland would become largely dependent on Germany, functioning as little more than a client state . The Poles feared that their independence would eventually be threatened altogether; historically Hitler had already denounced the right of Poland to independence in 1930, writing that Poles and Czechs were a "rabble not worth a penny more than the inhabitants of Sudan or India. How can they demand

2378-541: The Polish Army by about 1/3. Germany had a substantial numeric advantage over Poland and had developed a significant military before the conflict. The Heer (army) had 3,472 tanks in its inventory, of which 2,859 were with the Field Army and 408 with the Replacement Army . 453 tanks were assigned into four light divisions, while another 225 tanks were in detached regiments and companies. Most notably,

2460-548: The Polish Army during the invasion of 1939 was the 7TP light tank. It was the first tank in the world to be equipped with a diesel engine and 360° Gundlach periscope . The 7TP was significantly better armed than its most common opponents, the German Panzer I and II , but only 140 tanks were produced between 1935 and the outbreak of the war. Poland had also a few relatively modern imported designs, such as 50 Renault R35 tanks and 38 Vickers E tanks. The Polish Navy

2542-838: The Polish army was effectively defeated even before the British Expeditionary Force could be transported to Europe, with the bulk of the BEF in France by the end of September. On 17 September, the Soviet Red Army invaded Eastern Poland , the territory beyond the Curzon Line that fell into the Soviet " sphere of influence " according to the secret protocol of the Molotov–Ribbentrop Pact; this rendered

2624-730: The Polish plan of defence obsolete. Facing a second front, the Polish government concluded the defence of the Romanian Bridgehead was no longer feasible and ordered an emergency evacuation of all troops to neutral Romania . On 6 October, following the Polish defeat at the Battle of Kock , German and Soviet forces gained full control over Poland. The success of the invasion marked the end of the Second Polish Republic, though Poland never formally surrendered. On 8 October, after an initial period of military administration , Germany directly annexed western Poland and

2706-563: The Polish problem by military means" through the Case White scenario. In May, in a statement to his generals while they were in the midst of planning the invasion of Poland, Hitler made it clear that the invasion would not come without resistance as it had in Czechoslovakia: With minor exceptions German national unification has been achieved. Further successes cannot be achieved without bloodshed. Poland will always be on

2788-470: The Polish-German border and lacked compact defence lines and good defence positions along disadvantageous terrain. That strategy also left supply lines poorly protected. One-third of Poland's forces were massed in or near the Polish Corridor, making them vulnerable to a double envelopment from East Prussia and the west. Another third was concentrated in the north-central part of the country, between

2870-567: The September Campaign, not all of those aircraft were mobilized. By 1 September, out of about 120 heavy bombers PZL.37s produced, only 36 PZL.37s were deployed, the rest being mostly in training units. All those aircraft were of indigenous Polish design, with the bombers being more modern than the fighters, according to the Ludomił Rayski air force expansion plan, which relied on a strong bomber force. The Polish Air Force consisted of

2952-463: The Silesian Voivodeship also was a major producer of food, in spite of its small size. According to the 1931 Polish census , 92.3% of the population stated Polish as their mother tongue. Germans made up 7% and Jews only 1.5%. Poles lived mainly in the villages (95.6% of the population there), while Germans and Jews preferred cities (12.9% of Polish Upper Silesian cities' population was German, especially Bielsko and Katowice ). Population density

3034-493: The Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. One of the aims of the invasion was to divide Polish territory at the end of the operation; Poland was to cease to exist as a country and all Poles ("inferior people") were to be exterminated. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing

3116-658: The Soviets agreed to divide Eastern Europe, including Poland, into two spheres of influence ; the western one-third of the country was to go to Germany and the eastern two-thirds to the Soviet Union. The German assault was originally scheduled to begin at 4:00 a.m. on 26 August. However, on 25 August, the Polish-British Common Defence Pact was signed as an annex to the Franco-Polish alliance. In this accord, Britain committed itself to

3198-486: The administration was headed by a voivode appointed by the president of Poland to act as a representative of the central government. In mid-1939, in the wake of invasion , the population of the voivodeship was 1,533,500 (together with Trans-Olza , annexed in October 1938. Its total area was 5,122 square kilometres (1,978 sq mi). The voivodeship was divided into the following counties; with largest cities based on

In case of a failure to defend most of the territory, the army was to retreat to the south-east of the country, where the rough terrain, the Stryj and Dniestr rivers, valleys, hills and swamps would provide natural lines of defence against the German advance, and

3362-479: The construction of numerous coal mines and steelworks. For this reason, this Voivodeship was crucial to Polish armaments production. However, its location on the border with Germany made it vulnerable. In the mid-1930s, the Polish government decided to move some sectors of heavy industry to the nation's heartland, creating the Central Industrial Region . Due to efficient agricultural practices,

3444-420: The defence of Poland, guaranteeing to preserve Polish independence. At the same time, the British and the Poles were hinting to Berlin that they were willing to resume discussions—not at all how Hitler hoped to frame the conflict. Thus, he wavered and postponed his attack until 1 September, managing to in effect halt the entire invasion "in mid-leap". However, there was one exception: on the night of 25–26 August,

3526-523: The development of industry, especially in the armaments industry in ethnically Polish areas. Moreover, Poland had to deal with damage caused by World War I . This resulted in the need to build a defense industry from scratch. Between 1936 and 1939, Poland invested heavily in the newly created Central Industrial Region . Preparations for a defensive war with Germany were ongoing for many years, but most plans assumed fighting would not begin before 1942. To raise funds for industrial development, Poland sold much of

3608-407: The expectation that the Western Allies would honor their treaty obligations and quickly start an offensive of their own, the French and the British expected the war to develop into trench warfare, much like World War I. The Polish government was not notified of the strategy and based all of its defence plans on promises of quick relief by the Western Allies. Polish forces were stretched thinly along

3690-462: The expensive, unproven inventions since then. In spite of this, Polish cavalry brigades were used as mobile mounted infantry and had some successes against both German infantry and cavalry. An average Polish infantry division consisted of 16,492 soldiers and was equipped with 326 light and medium machine guns, 132 heavy machine guns, 92 anti-tank rifles and several dozen light, medium, heavy, anti-tank and anti-airplane field artillery. Contrary to

The Soviet Union incorporated its newly acquired areas into its constituent Byelorussian and Ukrainian republics , and immediately started a campaign of Sovietization . In the aftermath of the invasion, a collective of underground resistance organizations formed

3854-590: The ground—in fact it was successfully dispersed before the conflict started and not a single one of its combat planes was destroyed on the ground in the first days of the conflict. In the era of fast progress in aviation the Polish Air Force lacked modern fighters, vastly due to the cancellation of many advanced projects, such as the PZL.38 Wilk and a delay in the introduction of a completely new modern Polish fighter PZL.50 Jastrząb . However, its pilots were among

3936-486: The increased number of overflights by high-altitude reconnaissance aircraft and cross-border troop movements signaled that war was imminent. On 29 August, prompted by the British, Germany issued one last diplomatic offer, with Fall Weiss yet to be rescheduled. That evening, the German government responded in a communication that it aimed not only for the restoration of Danzig but also the Polish Corridor (which had not previously been part of Hitler's demands) in addition to

4018-580: The invasion to commence soon afterwards. On 29 August, Polish Minister of Foreign Affairs Józef Beck ordered military mobilization , but under the pressure from Great Britain and France, the mobilization was cancelled. When the final mobilization started, it added to the confusion. On 30 August, the Polish Navy sent its destroyer flotilla to Britain, executing the Peking Plan . On the same day, Marshal of Poland Edward Rydz-Śmigły announced

4100-707: The main Polish army was to be encircled and destroyed west of the Vistula . Fall Weiss was initiated on 1 September 1939 and was the first operation of Second World War in Europe . The Polish determination to deploy forces directly at the German-Polish border, prompted by the Polish-British Common Defence Pact, shaped the country's defence plan, " Plan West ". Poland's most valuable natural resources, industry and population were along

4182-659: The major cities of Łódź and Warsaw. The forward positioning of Polish forces vastly increased the difficulty of carrying out strategic maneuvres, compounded by inadequate mobility, as Polish units often lacked the ability to retreat from their defensive positions, as they were being overrun by more mobile German mechanized formations. Katowice Voivodeship Katowice Voivodeship ( Polish : województwo katowickie ) can refer to one of two political entities in Poland : Katowice Voivodeship (1) , initially "Silesian-Dabrowa Voivodeship" ( Polish : województwo śląsko-dąbrowskie ),

4264-531: The mobilization of Polish troops. However, he was pressured into revoking the order by the French, who apparently still hoped for a diplomatic settlement, failing to realize that the Germans were fully mobilized and concentrated at the Polish border. During the night of 31 August, the Gleiwitz incident , a false flag attack on the radio station, was staged near the border city of Gleiwitz in Upper Silesia by German units posing as Polish troops, as part of

4346-517: The modern equipment it produced. In 1936, a National Defence Fund was set up to collect funds necessary for strengthening the Polish Armed forces. The Polish Army had approximately a million soldiers, but not all were mobilized by 1 September. Latecomers sustained significant casualties when public transport became targets of the Luftwaffe . The Polish military had fewer armored forces than

4428-766: The new methods were nicknamed " Blitzkrieg " (lightning war). While historian Basil Liddell Hart claimed "Poland was a full demonstration of the Blitzkrieg theory", some other historians disagree. Aircraft played a major role in the campaign. Bombers also attacked cities, causing huge losses amongst the civilian population through terror bombing and strafing. The Luftwaffe forces consisted of 1,180 fighters , 290 Ju 87 Stuka dive bombers, 1,100 conventional bombers (mainly Heinkel He 111s and Dornier Do 17s ), and an assortment of 550 transport and 350 reconnaissance aircraft. In total, Germany had close to 4,000 aircraft, most of them modern. A force of 2,315 aircraft

The invasion was referred to by Germany as the 1939 Defensive War ( Verteidigungskrieg ) since Hitler proclaimed that Poland had attacked Germany and that "Germans in Poland are persecuted with a bloody terror and are driven from their homes. The series of border violations, which are unbearable to

4592-428: The requested Polish representative had failed to arrive by midnight. When Polish Ambassador Lipski went to see Ribbentrop later on 31 August to indicate that Poland was favorably disposed to negotiations, he announced that he did not have the full power to sign, and Ribbentrop dismissed him. It was then broadcast that Poland had rejected Germany's offer, and negotiations with Poland came to an end. Hitler issued orders for

4674-408: The requirement for an immediate arrival of a Polish representative with full signing powers as an unacceptable ultimatum . On the night of 30/31 August, German Foreign Minister Joachim von Ribbentrop read a 16-point German proposal to ambassador Nevile Henderson . When the ambassador requested a copy of the proposals for transmission to the Polish government, Ribbentrop refused, on the grounds that

4756-671: The rest of Poland alone. German hegemony over Central Europe was also at stake. In private, Hitler said in May that Danzig was not the important issue to him, but the creation of Lebensraum for Germany. With tensions mounting, Germany turned to aggressive diplomacy. On 28 April 1939, Hitler unilaterally withdrew from both the German-Polish Non-Aggression Pact of 1934 and the Anglo-German Naval Agreement of 1935. Talks over Danzig and

4838-510: The results of the plebiscite, which was held on 20 March 1921, Upper Silesia was divided between Poland and Germany . The Polish part was incorporated as the Silesian Voivodeship. After the referendum of 1921, the German-Polish Accord on East Silesia (Geneva Convention) was concluded on 15 May 1922 and dealt with the constitutional and legal future of Upper Silesia , as part of it had become Polish territory. The voivodeship

The population of the Free City of Danzig was strongly in favour of annexation by Germany, as were many of the ethnic German inhabitants of the Polish territory that separated the German exclave of East Prussia from the rest of the Reich.

In late 1938, the Polish Air Force also ordered 300 advanced PZL.46 Sum light bombers, but due to a delay in starting mass production, none of them were delivered before 1 September.

It is a matter of expanding our living space in the east, of making our food supply secure, and solving the problem of the Baltic states. To provide sufficient food you must have sparsely settled areas. There is therefore no question of sparing Poland, and the decision remains to attack Poland at the first opportunity.

In fact, the Soviets agreed not to aid France or the UK in the event of their going to war with Germany over Poland and, in a secret protocol of the pact, the Germans and

5412-445: The western border in Eastern Upper Silesia . Polish policy centred on their protection, especially since many politicians feared that if Poland retreated from the regions disputed by Germany, Britain and France would sign a separate peace treaty with Germany like the 1938 Munich Agreement and allow Germany to stay in those regions. The fact that none of Poland's allies had specifically guaranteed Polish borders or territorial integrity

The operation plan had not been elaborated in detail and concerned only the first stage of operations. The British and the French estimated that Poland would be able to defend itself for two to three months, and Poland estimated it could do so for at least six months. While Poland drafted its estimates based upon

The invasion is also known in Poland as the September campaign ( Polish : kampania wrześniowa ) or 1939 defensive war (Polish: wojna obronna 1939 roku ) and known in Germany as the Poland campaign ( German : Überfall auf Polen, Polenfeldzug ). German forces invaded Poland from the north, south, and west the morning after

5658-474: The wider Operation Himmler . On 31 August, Hitler ordered hostilities against Poland to start at 4:45 the next morning. However, partly because of the earlier stoppage, Poland finally managed to mobilize only about 70% of its planned forces (only about 900,000 of 1,350,000 soldiers planned to mobilize in first order), and because of that many units were still forming or moving to their designated frontline positions. The late mobilization reduced combat capability of

Overall, the Germans enjoyed numerical and qualitative aircraft superiority. Poland had only about 600 aircraft, of which only PZL.37 Łoś heavy bombers were modern and comparable to their German counterparts. The Polish Air Force had roughly 185 PZL P.11 and some 95 PZL P.7 fighters, 175 PZL.23 Karaś Bs, 35 Karaś as light bombers. However, for

6068-506: Was advocated by some generals, including Heinz Guderian , would have had the armour punching holes in the enemy's front and ranging deep into rear areas, but the campaign in Poland would be fought along more traditional lines. That stemmed from conservatism on the part of the German High Command, which mainly restricted the role of armour and mechanized forces to supporting the conventional infantry divisions. Poland's terrain

6150-474: Was another Polish concern. These reasons made the Polish government disregard French advice to deploy the bulk of its forces behind natural barriers, such as the Vistula and San Rivers, despite some Polish generals supporting the idea to be a better strategy. The West Plan allowed the Polish armies to retreat inside the country, but that was supposed to be a slow retreat behind prepared positions intended to give

6232-687: Was assigned to Weiss . Due to its earlier participation in the Spanish Civil War , the Luftwaffe was probably the most experienced, best-trained and best-equipped air force in the world in 1939. Emerging in 1918 as an independent country after 123 years of the Partitions of Poland , the Second Polish Republic , when compared with countries such as United Kingdom or Germany, was a relatively indigent and mostly agricultural country. The partitioning powers did not invest in

6314-406: Was decided to temporarily implement the production of the fighter PZL P 11.G Kobuz. Nevertheless, due to the outbreak of the war, not one of the ordered 90 aircraft of this type were delivered to the army. The tank force consisted of two armored brigades, four independent tank battalions and some 30 companies of TKS tankettes attached to infantry divisions and cavalry brigades. A standard tank of

6396-532: Was one of the most economically-developed parts of Poland. It had been granted autonomous status by an Act of the Polish Sejm dated 15 July 1920. That status was secure until the May Coup in 1926, which started various attempts to limit it in favour of a strong and centralised state. After the German invasion of Poland, the voivodeship was dissolved on 8 October 1939, and its territory was incorporated into

6478-469: Was the highest in the country at 299 persons per 1 km. On 1 January 1937, forested areas made up 27.9% of the province. Rail density was the highest in the country at 18.5 km per 100 km. In 1931, the illiteracy rate was the lowest in the country at 1.5% of the population. After the First World War a dispute arose about the future of Upper Silesia . This part of the Silesia region

6560-501: Was the least affected by centuries of Germanisation . The population was predominantly Slavic , especially in rural areas, although over the years the percentage of the German population increased and in many cities Germans constituted the majority. Many of Slavic people considered themselves Poles (majority), and some Czechs (minority). The rest did not feel any strong connections to either of those nations; according to Wojciech Korfanty 's estimations, this last group represented up to

6642-467: Was to be supported by Panzers and small numbers of truck-mounted infantry (the Schützen regiments, forerunners of the panzergrenadiers ) to assist the rapid movement of troops and concentrate on localized parts of the enemy front , eventually isolating segments of the enemy, surrounding, and destroying them. The prewar "armoured idea", which an American journalist in 1939 dubbed Blitzkrieg , which

6724-478: Was well suited for mobile operations when the weather co-operated; the country had flat plains , with long frontiers totalling almost 5,600 km (3,500 mi). Poland's long border with Germany on the west and north, facing East Prussia, extended 2,000 km (1,200 mi). It had been lengthened by another 300 km (190 mi) on the southern side in the aftermath of the 1938 Munich Agreement. The German incorporation of Bohemia and Moravia and creation of
