The Military History of Poland

Poland has had several states and, for 123 years, none. This page follows its wars era by era, names the state that fought each of them and tells the wars with its neighbors from more than one side. Its best-known battles include the Battle of Grunwald (1410), the relief of Vienna (1683), the Battle of Warsaw (1920) and Monte Cassino (1944), and every one of the 57 battles we cover is listed by era below. ²

Which states does Polish military history cover?

Polish statehood is dated to Mieszko I, the Piast ruler baptized in 966. The Piast kingdom was followed by the Jagiellonian union with the Grand Duchy of Lithuania, agreed at Krewo in 1385, and in 1569 by the Union of Lublin, which turned the two states into one, the Polish-Lithuanian Commonwealth (Rzeczpospolita). ³

The Commonwealth was a joint state, and its history is also Lithuanian, Belarusian and Ukrainian history. At its height in the early 17th century it was one of the largest states in Europe, home to Poles, Lithuanians, Ruthenians, Germans, Jews, Tatars, Armenians and Scots. When this page says Poland for the years after 1569, it means that Commonwealth; Lithuanian commanders such as the hetman Jan Karol Chodkiewicz served it as much as Polish ones. ⁴

Russia, Prussia and Austria divided the Commonwealth in three partitions, the last in 1795. For the next 123 years Polish armies fought under other flags or in risings: the Legions in French service, the Duchy of Warsaw that Napoleon created in 1807, the Congress Kingdom tied to Russia from 1815. Independence returned in November 1918 with the Second Polish Republic. After 1945 came the communist Polish People's Republic in the Soviet sphere. ⁵

The Piast kingdom, 966 to 1370

From the mid-12th century the Piast realm was divided among branches of the dynasty, and new enemies found it weak. Its main foes were the Teutonic Knights, invited in 1226 by a Polish duke to fight the pagan Prussians, and the Mongols and Tatars. In 1241 the Mongol invasion swept through the country, and on 9 April Duke Henry II the Pious was killed with much of his army at Legnica, a heroic defeat that became part of national memory. ⁶

By 1320 Władysław I the Short had reunited enough of the kingdom to be accepted abroad as king of an independent Poland; our article on Płowce (1331) covers his war with the Teutonic Knights. His son Casimir III the Great preferred diplomacy and concessions toward Bohemia and the Knights and expanded to the east instead. The Piast line ended with his death in 1370. ⁷

The Jagiellonian union and Grunwald

The marriage of Queen Jadwiga of Poland to Jogaila, Grand Duke of Lithuania, who took the name Władysław II Jagiełło, joined the two states against a common enemy, the Teutonic Order. Lithuania accepted Latin Christianity, which removed the Knights' main reason to crusade against it. ⁸

In July 1410 a Polish-Lithuanian army invaded Prussia and met the Order near Grunwald and Tannenberg on 15 July. The king and his Lithuanian grand duke led an army joined, as the chroniclers have it, by Tatar skirmishers and Bohemian soldiers. The Grand Master Ulrich von Jungingen was killed, his charge failed and the Order's army broke. Grunwald was a Polish-Lithuanian victory that halted the Knights' expansion. ⁹

The victors could not take the Order's stronghold at Marienburg (Malbork). In the peace of 1411 the Knights gave up only Samogitia and the Dobrzyń land and paid a heavy indemnity, but their military power was broken. By the 16th century the Order had been reduced to vassalage, and Poland-Lithuania held its place among the largest states of Europe. ¹⁰

The Commonwealth at war, 1569 to 1648

After 1572 the nobles elected their kings, often foreigners. Sigismund III Vasa fought long wars against Muscovy and his native Sweden that at times came close to conquering Muscovy and the Baltic coast. Our guide to the Polish-Swedish War of 1600 to 1629 and our article on Kircholm (1605) cover the Swedish war in Livonia, where the Lithuanian hetman Jan Karol Chodkiewicz commanded; in 1610 Hetman Stanisław Żółkiewski won at Klushino and then entered Moscow, where the boyars accepted Sigismund's son Władysław as tsar. The success did not last. ¹¹

The south brought defeats as well as victories. The Commonwealth suffered an unexpected and crushing defeat at Cecora (Țuțora) in 1620. In 1621 its army withstood a grueling siege by Sultan Osman II at Khotyn (Chocim), and a peace compromise followed. Our articles on Cecora in 1595, Oliwa and Trzciana cover other fights with the Ottomans and Sweden in these decades. ¹²

The Deluge and the Cossack war, 1648 to 1667

In 1648 a Cossack rising under Bohdan Khmelnytsky began in Ukraine and became a war of the Ukrainian people against the Commonwealth's nobility. Our article on Berestechko (1651) covers its largest battle. The war went on, and when the rebels won Muscovy's intervention, the Pereiaslav agreement of 1654 placed the Cossack Hetmanate under the tsar's protection. Ukrainian and Polish memory of these years differ, and both belong to the story. ¹³

Muscovy then conquered much of the east, and in 1655 Charles X Gustav of Sweden invaded and overran most of the rest. King John Casimir fled the country. This was the Deluge (Potop). The defense of the Jasna Góra monastery at Częstochowa became its symbol, and under Stefan Czarniecki the Poles and Lithuanians drove the Swedes out by 1657 (our article on the siege of Kolding follows Czarniecki's later campaign in Denmark). The Truce of Andrusovo in 1667 still left Smolensk and Ukraine east of the Dnieper to Muscovy. ¹⁴

Sobieski and the relief of Vienna

John III Sobieski won fame against the Ottomans at Khotyn in 1673, and the victory helped carry him to the throne; he was elected king in 1674 and reigned until 1696 (see our biography of Jan III Sobieski). ¹⁵

In 1683 he led a relief army to Vienna, then besieged by the Ottomans. The Battle of Vienna on 12 September was a coalition victory: the relief force combined Polish troops with Imperial forces and contingents from Saxony, Franconia, Bavaria and other states, and while Sobieski as the highest-ranking ruler held overall command, sources also describe a joint command with Charles of Lorraine. It was the Commonwealth's last great military triumph, followed by the long war that pushed the Ottomans back, the Great Turkish War. ¹⁶

Our separate guide to the wars of the Polish-Lithuanian Commonwealth follows these wars in more detail, and the ranking of the winged hussars' greatest battles picks out the most famous fights of the hussars.

Reform, partitions and Kościuszko, 1764 to 1795

By the 18th century the Commonwealth had become a Russian protectorate in all but name. Our guide to the Great Northern War (1700 to 1721) follows the Swedish, Saxon and Russian armies that fought across it in the first decades of that century. Russia, Prussia and Austria took their first slice of it in 1772. The reformers answered with the Constitution of 3 May 1791, but conservative nobles formed the Confederation of Targowica and called in Russia. Russia invaded, the king went over to Targowica, and Russia and Prussia carried out the Second Partition in 1793; our article on Zieleńce covers a Polish victory in that war of 1792. ¹⁷

In 1794 Tadeusz Kościuszko, a veteran of the American Revolution, led a national uprising. His insurgent army, which included peasants, won some early successes, among them Racławice, but fell before superior Russian forces, and in 1795 the Third Partition wiped the Commonwealth from the map. See our biography of Kościuszko. ¹⁸

Legions, the Duchy of Warsaw and the uprisings, 1797 to 1864

In 1797 Jan Henryk Dąbrowski raised Polish Legions in Italy, in the service of the Lombard republic allied to France; Józef Wybicki wrote for them the song that became the Polish national anthem. Volunteer legions attached themselves to Bonaparte's armies in the hope of a restored Poland, so these were French wars rather than Polish ones; our articles on the Trebbia in 1799, Somosierra and Tarutino follow Polish troops in Italy, Spain and Russia, and our guide to Napoleon's invasion of Russia covers the campaign of 1812. ¹⁹

In 1807 Napoleon created the Duchy of Warsaw from Prussian lands, and in 1809 its army under Prince Józef Poniatowski won back land taken by Austria (our article on Raszyn covers that war). After Napoleon's fall the Congress of Vienna replaced the Duchy with the Congress Kingdom of Poland, tied to the Russian Empire, in 1815. ²⁰

In November 1830 Polish troops in Warsaw rose against Russian rule, and the November Uprising became a Polish-Russian war. After hard fighting, among others at Olszynka Grochowska and Ostrołęka, Russian troops stormed Warsaw in September 1831. The January Uprising of 1863 ended in another defeat, after which the Russian-ruled Polish lands lost their last separate status; our article on Iłża covers one of its fights. ²¹

Independence and the wars for the borders, 1914 to 1921

In World War I Poles fought in the armies of all three partitioning powers; about 2 million served and some 450,000 died. Józef Piłsudski formed Polish legions on the side of the Central Powers against Russia on the Eastern Front. When those empires collapsed in November 1918, he took control in Warsaw of an independent Poland, absent from the map for 123 years. ²²

The eastern frontiers were settled by force. Pilsudski's government wanted Polish rule over western Ukraine, which set it against the Ukrainians as well as Soviet Russia; our articles on Lwów (Lviv) in 1918 and the capture of Ławica cover the fighting of 1918 and 1919, which is also part of Ukrainian and German history. ²³

The Polish-Soviet War turned on a Polish and Ukrainian offensive that took much of Ukraine in April 1920 and a Red Army counterattack that drove almost to Warsaw. In mid-August Piłsudski struck from the Wieprz river into the Soviet flank with a strike force under Edward Rydz-Śmigły, helped by a Soviet decision to send forces south toward Lwów. The Battle of Warsaw was followed by the Niemen and the compromise Peace of Riga in 1921. ²⁴

The battle is popularly called the Miracle on the Vistula, but the historian Norman Davies calls it a hard-fought battle, not a miracle, and rejects the later claims that the French General Weygand or Providence won it. Our articles on Zadwórze and Komarów cover the cavalry fighting of that summer, and a separate guide collects the battles that secured independence. ²⁵

How Poland fought in World War II: 1939

Germany invaded Poland on 1 September 1939, after the staged Gleiwitz incident, with about 1.5 million men, 2,750 tanks and 2,315 aircraft; its superiority was overwhelming. Our articles follow the Polish defense at Westerplatte, Mokra, Mława and Wizna. Britain and France declared war on Germany on 3 September but gave no effective help in the field. ²⁶

Our article on the Battle of the Bzura covers the Polish counteroffensive of mid-September. On 17 September the Red Army crossed the eastern border under the secret protocol of the German-Soviet pact (our article: the Soviet invasion of Poland). Warsaw surrendered on 27 or 28 September, depending on the source, and the two invaders partitioned Poland on 29 September; the last operational Polish unit surrendered on 6 October (see the defense of Hel and the Battle of Kock). ²⁷

Occupation, the Holocaust and the Warsaw Uprising

Both occupiers set out to destroy Polish society. In 1940 the Soviet security police murdered thousands of captured Polish officers and members of the intelligentsia, the crime known as the Katyn massacre. Germany made occupied Poland the main killing ground of the Holocaust: the Germans murdered at least 3 million Jewish citizens of Poland, almost the whole Jewish community, and killed an estimated 1.8 to 1.9 million non-Jewish Polish civilians. ²⁸

On 1 August 1944 the Home Army (Armia Krajowa) began the Warsaw Uprising, meaning to free the city before the Red Army, then on the east bank of the Vistula, entered it. Soviet forces did not intervene; historians still debate why. After 63 days the insurgents capitulated on 2 October, and German troops destroyed most of the city during and after the fighting. The Rising remains significant but controversial in Polish memory. ²⁹

Polish forces in the West and the East

Poland's armed forces fought on in exile under the government in London. The Highland Brigade fought at Narvik in 1940, Polish pilots flew in the Battle of Britain, and the Carpathian Brigade held Tobruk in 1941. General Władysław Anders, freed from a Soviet prison, formed an army in the Soviet Union that left for the Middle East and became the Polish II Corps. ³⁰

At Monte Cassino in May 1944 the II Corps made the fourth Allied attempt on the abbey after Indian and New Zealand units had failed; its renewed assault took the ruins on 18 May. The corps lost 860 dead and 2,822 wounded there and went on to Ancona and Bologna. In Normandy General Stanisław Maczek's 1st Armoured Division helped close the pocket at Falaise, and Stanisław Sosabowski's paratroopers dropped in Operation Market Garden. ³¹

Our article on the Seelow Heights covers the Polish units that fought alongside the Red Army in 1945.

After 1945

Poland came out of the war as a communist state in the Soviet sphere, its borders moved west: the Allies gave it German lands up to the Oder and Neisse rivers, while about 3 million Poles were moved from the eastern lands annexed by the Soviet Union. Germany lost these eastern territories, from which millions of Germans were expelled. ³²

Polish commanders

The Commonwealth's hetmans included Jan Karol Chodkiewicz, the Lithuanian who commanded at Kircholm and Khotyn, Stanisław Żółkiewski of Klushino, Stanisław Koniecpolski and Stefan Czarniecki; its warrior kings were Stefan Batory and Jan III Sobieski. In the partition era Tadeusz Kościuszko and Józef Poniatowski led armies, and in the 20th century Józef Piłsudski, Władysław Anders, Stanisław Maczek and Stanisław Sosabowski. Our guide to the greatest Polish commanders ranks them. ³³
