Campaign in Poland
The Campaign in Poland consisted of military action between Germany and Poland from 1 September, 1939. It concluded with the complete and absolute defeat of Poland. Germany argued their response was to "Macedonian conditions" on their borders and twenty years of Poland's deliberate provocations. Finally, Poland's partial mobilisation against Germany from April 1939 was followed by her full mobilisation announced on August 30th.
Having both guaranteed Poland assistance if its borders were invaded, Britain and France declared war on Germany on September 3rd. By these actions they turned what should have been a localised action between two nation-states into World War II, as Hitler had stated the invasion of Poland would be a localised war, and firmly believed that neither Britain or France would intervene.
On 17 September the Soviet Union, under a secret clause of the German-Soviet Non-Aggression Pact, invaded the eastern forty percent of Poland, subsequently imprisoning thousands of officers as Prisoners-of-War, and some civilian intellectuals etc., who were all later executed in the infamous Katyn massacre.
It should be emphasized that their invasion of Poland (and in June 1940: Lithuania, Latvia, Estonia, and Finland) by the Red Army failed to cause a declaration of war by either Great Britain or France against the Soviet Union.
Summary of Causes
As a result of the imposed Treaty of Versailles (June 1919), among many other penalties imposed on Germany, was the loss of Danzig and Memel and the transfer to Poland of provinces in eastern Germany largely populated by Germans.
- "The [eastern] frontiers of Germany, as laid down by Articles 27 and 28 of the Treaty, constitute the greatest violation of the principles of self-determination, and are mere allotments of territory, marked out at random, and in violation of International Law....The labour of centuries was destroyed at a blow." ~ Francesco Nitti, former Prime Minister of Italy.
Every German Government in the 1919-1939 period publicly declared that they would never accept the imposed eastern borders, and their aim was for revision by political means. Under Versailles, a pre-condition was Poland's signature to the appended "Treaty for the Protection of Minorities". However, under Poland's occupation the German population suffered continuous criminal actions leading to emigration, expulsions, and even deaths, resulting in constant complaints and protests to the League of Nations.
- "As for the Polish Corridor, it may be definitely said that Germany will never tolerate a condition of things by which East Prussia is separated from the German Reich." ~ Tomáš Masaryk, Czech Statesman..
- "There [the Corridor] lies the root of the next war." ~ Marshal Ferdinand Foch.
The so-called Polish Corridor was the pre-1919 German province of West Prussia which now separated East Prussia and Danzig from Pomerania and the Reich. For several years the German Government had been making proposals to the Polish Governments about the 'corridor' to make all forms of transit easier. These included an extra-territorial autobahn and non-interference (passports, guards, customs etc) for German trains not stopping in the 'corridor'. These proposals were flatly refused by Poland. By August 1939 the German position had hardened: they demanded a plebiscite of the population as it was in 1910 with a view to the return of the 'corridor' (but not the province of Posen).
Polish intransigence over the status of, and countless incidents in Danzig, with its 98% German population, was another major factor. In mid-1939 the democratically elected Danzig Senate called for Danzig to be reunited with the Reich, echoed in Germany itself.
Even before Versailles, President Theodore Roosevelt stated prophetically:
- "The nation has as a matter of course a right to abrogate a treaty in a solemn and official manner for what she regards as a sufficient cause, just exactly as she has a right to declare war or exercise another power for a sufficient cause."
This would not be lost on Germany. The Polish Foreign Minister, Josef Beck, and his military hierarchy "were convinced that Poland could withstand a German attack". Poland had been encouraged in her provocations by Great Britain's March 1939 'blank cheque' guaranteeing Poland's sovereignty and borders.
Poland had begun partially mobilising its army since 25 March 1939 and on August 30th announced full mobilisation. It has long been accepted that mobilising armed forced against another country is a de facto declaration of war. There were also rumours of an imminent Polish attack on Danzig, due to the new Polish blockade of the Free City. At 8 p.m. on August 31st uniformed Polish soldiers, speaking Polish, attacked the Gleiwitz broadcasting station in Upper Silesia. The staff were all locked in the cellar. A soldier then broadcast:
- "This is Gleiwitz. The [radio] station is in Polish hands."
By the time the first police arrived from their station 1 km away the intruders had left. Upper Silesia had for 20 years been the scene of Polish nationalist unrest and terrorism. It is interesting that so many since have labelled Germany's reaction to these activities as belligerent.
"During the night" of 31 August - 1 September, 1939, the Poles blew up the massive and principal railway bridge at Dirschau and fighting took place with the Danzigers. This would appear to show that Poland was the aggressor. At about 5 a.m., the German battleship Schleswig-Holstein, on a courtesy visit in Danzig harbour, was given orders to open fire on the illegal Polish military base at the Westerplatte at Danzig. Some consider these to be the opening shots of the German-Polish war. The following day German destroyers arrived to assist the bombardment of Westerplatte. Meanwhile, Polish forces attacked Danzig from the west but were repulsed.
Berlin Radio at 5.40 a.m. broadcast the following: "Fuhrer issued the following Proclamation to the army. The Polish State has refused a peaceful settlement of relations which I desired and has appealed to arms."
Polish army demolition experts having blown up the vast railway bridge at Dirschau, built by Germany before The Great War, then proceeded to do the same to the massive bridge at Graudenz; Swedish diplomat Johan Dahlerus telephoned Charles Spencer at the London Foreign Office saying "The Poles do not want to negotiate. They are sabotaging everything." The German city of Beuthen in Upper Silesia was bombarded by Polish artillery; the German Consul in Crakow was murdered.
On the same morning the German Wehrmacht invaded Poland at four points. Telegraph and telephone wires were cut about 4 a.m., by whom is uncertain. The railway station at Granica was occupied by German troops; Dirschau was reportedly bombed; north-west of Naklo (Nakel) armoured German divisions crossed the frontier and fighting generally was in progress by 6 a.m. when the attack on the Westerplatte (Danzig) was reported.
The British Ambassador at Warsaw reported further on German activities (always upon information provided by the Poles): Myszyniec was attacked at 5 a.m., German forces crossed the river Vistula between then and 6.45, near Deutsch-Eylau. Tanks observed near Śmiłów; weak attack in direction of Leszno (Lissa); air raid on Posen; attack between Neu-Mittelwalde and Ruchtal; tank attack on front at Praszka-Krzepice; attack on Lubliniec and Tarnowskie Gory (Tarnowitz) each by one battalion with tanks; tank attack on front at Gleiwitz-Ratibor (Upper Silesia); air raids on the aerodromes and railway stations of Kattowitz and Crakow.
As a result of the German invasion, two days later, on 3 September, Britain and France declared war on Germany. What began and should have remained a localized conflict over the fate of an ancient German city, Danzig, and negotiable border revisions, between two continental European nations, namely Germany and Poland, was now expanded by Britain and France into a continental war involving all of Europe's major powers.
Following the outbreak of war significant atrocities and murders of ethnic Germans who lived in Poland, usually having lived and remained in the German provinces given to Poland under the Versailles Treaty. These were carried out by both the Polish military as well as the civilian population. The worst were those carried out in Bromberg and surrounding towns and villages.
Defeat for Poland
After 37 days (October 6, 1939) Poland capitulated. The Polish government withdrew through Romania into exile in England. This rapid and forceful action by Germany became known by the term Blitzkrieg (lightning war).
