After the war they were dissolved. In the autumn of 1938, the Independent Operational Group Silesia was created with the purpose of capturing Trans-Olza from Czechoslovakia . Prior to World War II , operational groups were recreated on

The Polish–Soviet War was the longest lasting of the international engagements. The territory of what had become Poland had been a major battleground during World War I and the new country lacked political stability. It had won the hard-fought Polish–Ukrainian War against
276-610: A definitive ruling in regard to Poland's eastern border but on 8 December 1919, the Allied Supreme War Council issued a provisional boundary (its later version would be known as the Curzon Line ). It was an attempt to define the areas that had an "indisputably Polish ethnic majority". The permanent border was contingent on the Western powers' future negotiations with White Russia , presumed to prevail in

During the Polish–Soviet War, the Polish decryption of Red Army radio messages made it possible to use Polish military forces efficiently against Soviet Russian forces and to win many individual battles, most importantly

Some groups were formed during the final mobilization of late August 1939, while others were formed during the war as strategic considerations necessitated. Most were attached to armies, several however were independent. According to the Polish mobilization scheme, they were to become mobile reserves of

The event has been presented as the beginning of the war of liberation by the Polish side, or of Polish aggression by the Russian side. By late February, the Soviet westward offensive had come to a halt. As the low-level warfare continued, the Polish units crossed the Neman River, took Pinsk on 5 March and reached
644-615: A separate peace. Doing so worsened relations between Poland and the Ukrainians who had supported Petliura. The supporters felt that Ukraine had been betrayed by its Polish ally, which would be exploited by the Organization of Ukrainian Nationalists and contribute to the growing tensions and eventual anti-Polish massacres in the 1930s and the 1940s. By the end of 1921, most Poland-allied Ukrainian, Belarusian and White Russian forces had been annihilated by Soviet forces or had crossed

The Ukrainian People's Republic , led by Symon Petliura , had been allied with Poland under the Treaty of Warsaw , which was abrogated by the Treaty of Riga. The new treaty violated Poland's military alliance with the UPR, which had explicitly prohibited

On 21 November 1919, after contentious deliberations, the Allied Supreme War Council mandated Polish control over eastern Galicia for 25 years, with guarantees of autonomy for the Ukrainian population. The Conference of Ambassadors , which replaced
920-621: A year and a half for a full-scale war to develop. The Western powers considered any significant territorial expansion of Poland, at the expense of Russia or Germany, to be highly disruptive to the post-World War I order. Among other factors, the Western Allies did not want to give Germany and Russia a reason to conspire together. The rise of the unrecognized Bolshevik regime complicated this rationale. The Treaty of Versailles , signed on 28 June 1919, regulated Poland's western border. The Paris Peace Conference (1919–1920) had not made
1012-463: Is also referred to as the "War of 1920" ( Polish : Wojna 1920 roku ). The ending year of the conflict is variously given as either 1920 or 1921; this confusion stems from the fact that while the ceasefire came into force on 18 October 1920, the official treaty ending the war was signed on 18 March 1921. While the events of late 1918 and 1919 can be described as a border conflict and only in spring 1920 were both sides engaged in an all-out war ,

This was a relief for the government of Poland, a country heavily damaged and exhausted by the war, who also wanted to conclude peace talks. Piłsudski and his supporters, however, having failed in their quest, opposed the peace process. Peace talks began in Minsk on 17 August 1920, but

On 7 May, Polish and allied Ukrainian forces captured Kiev , though Soviet armies in the area were not decisively defeated. The offensive lacked local support, and many Ukrainians joined the Red Army rather than Petliura’s forces. In response, the Soviet Red Army launched a successful counteroffensive starting in June 1920. By August, Soviet troops had pushed Polish forces back to Warsaw . However, at

In 1920, Piłsudski's initially successful military offensive into Ukraine , whose aim was to establish an independent Ukraine in alliance with Poland, was met with a Soviet counter-offensive into central Poland.

This shift was accompanied by large population transfers which led to the expulsion of the Poles living east of the new border, and also moved most of the Ukrainian minority remaining in Poland to the former German territories that were ceded to Poland in compensation.

A Red Army assault between the Daugava and Berezina Rivers was repelled in October and the front had become relatively inactive with sporadic encounters only, as the line designated by Piłsudski to be the goal of the Polish operation in the north was reached. In autumn 1919, the Sejm voted to incorporate into Poland the conquered territories up to the Daugava and Berezina Rivers, including Minsk. The Polish successes in summer 1919 resulted from

After the collapse of the Central Powers and the Armistice of 11 November 1918 , Vladimir Lenin 's Soviet Russia annulled the Treaty of Brest-Litovsk and moved forces westward to reclaim the Ober Ost regions abandoned by the Germans. Lenin viewed the newly independent Poland as a critical route for spreading communist revolutions into Europe .

The Polish offensive was discontinued around the line of German trenches and fortifications from World War I, because of high likelihood of Poland's war with Weimar Germany over territorial and other issues.

Pressured by the National Democrat ideologue, Stanisław Grabski , the 100 km of extra territory was rejected, a victory for the nationalist doctrine and a stark defeat for Piłsudski's federalism .

The war ended with a ceasefire on 18 October 1920, and peace negotiations led to the Peace of Riga , signed on 18 March 1921. The treaty divided disputed territories between Poland and Soviet Russia.

As Piłsudski put it, "I am not worried about the strength of Russia; if I wanted to, I could go now, say to Moscow, and no one would be able to resist my power ...". The offensive was restrained in late summer by Piłsudski, because he did not want to improve

The Belarusian and Ukrainian independence movements saw the treaty as

Piłsudski had made many obfuscating statements, but never specifically stated his views regarding Poland's eastern borders or political arrangements he intended for the region.

Piłsudski had wanted to break up the Russian Empire and set up the Intermarium federation of various different states: Poland, Lithuania, Belarus, Ukraine and other Central and East European countries that emerged from the crumbling empires after World War I. In Piłsudski's vision, Poland would replace a truncated and vastly reduced Russia as

He had hoped that the new Poland-led union would become a counterweight to any potential imperialist intentions of Russia or Germany. Piłsudski believed that there could be no independent Poland without a Ukraine free of Russian control, thus his main interest was in splitting Ukraine from Russia. He used military force to expand
6624-473: The historian Andrzej Chwalba , however, the scenario was different in late 1919 and winter–spring 1920.

It was sharply criticized by his rival National Democrats, who demanded direct incorporation of the former Grand Duchy lands by Poland and signaled their opposition to Piłsudski's territorial and political concepts.
