The Battle of Warsaw was the decisive battle of the Polish-Soviet War, which began soon after the end of World War I in 1918 and lasting until the Treaty of Riga (1921).
The Battle of Warsaw was fought from 13 to 25 August 1920 as Red Army forces commanded by Mikhail Tukhachevski approached the Polish capital of Warsaw and nearby Modlin Fortress. On August 16, Polish forces commanded by Józef Pilsudski counter-attacked from the south, forcing the Russian forces into a disorganised withdrawal eastward and behind the Niemen River. Estimated Bolshevik losses were 10,000 killed, 500 missing, 10,000 wounded and 66,000 taken prisoner, compared with Polish losses of some 4,500 killed, 10,000 missing and 22,000 wounded.
Before the Polish victory at the Vistula, both the Bolsheviks and the majority of foreign experts considered Poland to be on the verge of defeat.

The Battle of Warsaw was the decisive battle of the Polish-Soviet War, which began soon after the end of World War I in 1918 and lasting until the Treaty of Riga (1921).
The Battle of Warsaw was fought from 13 to 25 August 1920 as Red Army forces commanded by Mikhail Tukhachevski approached the Polish capital of Warsaw and nearby Modlin Fortress. On August 16, Polish forces commanded by Józef Pilsudski counter-attacked from the south, forcing the Russian forces into a disorganised withdrawal eastward and behind the Niemen River. Estimated Bolshevik losses were 10,000 killed, 500 missing, 10,000 wounded and 66,000 taken prisoner, compared with Polish losses of some 4,500 killed, 10,000 missing and 22,000 wounded.
Before the Polish victory at the Vistula, both the Bolsheviks and the majority of foreign experts considered Poland to be on the verge of defeat. The stunning, unexpected Polish victory crippled the Bolshevik forces. In the following months, several more Polish victories secured Poland's independence and eastern borders.
PreludeThe Poles were fighting to preserve their newly regained independence, lost in the 1795 third partition of the Polish-Lithuanian Commonwealth, and to carve out the borders of a new multinational federation from the territories of their former partitioners, Russia, Germany and Austria-Hungary.
In 1919 the Bolsheviks had gained the upper hand in the Russian Civil War, having dealt crippling blows to the White Russians. Vladimir Lenin viewed Poland as a bridge to bring communism to Central and Western Europe, and the Polish-Bolshevik War seemed the perfect way to test Bolshevik strength. Bolshevik speeches asserted that the revolution was to be carried to western Europe on the bayonets of Soviet soldats and that the shortest route to Berlin and Paris lay through Warsaw.
The two sides were embroiled in conflict in the Ukraine, amidst competing territorial claims. After early setbacks against Poland in 1919, the Bolsheviks were overwhelmingly successful in a counter-offensive in early 1920 that eclipsed the Polish Kiev Operation, forcing a Polish retreat. By mid-1920, Poland's very survival was at stake and foreign observers expected it to collapse at any moment. The Soviet strategy called for a massed push toward the Polish capital, Warsaw. Its capture would have had a tremendous propaganda effect for the Soviets, who expected it not only to undermine the morale of the Poles, but to spark an international series of communist uprisings and clear the way for the Red Army to join the German Revolution.
The Soviet 1st Cavalry Army under Semyon Budyonny broke through Polish lines in early June 1920. This led to a collapse of all Polish fronts in the east. On July 4, 1920, Mikhail Tukhachevski's Western Front began an all-out assault in Belarus from the Berezina River, forcing Polish forces to retreat. On July 19 the Red Army seized Grodno an on July 28, it reached Bialystok. Three days later, the Brzesc Fortress was captured.
Battle plansBolshevikMikhail Tukhachevski planned to encircle and surround Warsaw by crossing the Vistula river, near Wloclawek, to the north and south of the city and launch an attack from the northwest. With his 24 divisions, he planned to repeat the classic maneuvre of Ivan Paskievich, who in 1831, during the November Uprising, had crossed the Vistula at Torun and reached Warsaw practically unopposed. This move would also cut the Polish forces off from Gdansk, the only port open to shipments of arms and supplies.
The main weakness of the Soviet plan was the poorly defended southern flank, secured only by the Pinsk Marshes and the weak Mozyr Group; the majority of the Soviet Southwest Front was engaged in the battle of Lwów.
The battleFirst phaseMeanwhile Bolsheviks pushed forward. Gay Dimitrievich Gay's Cavalry Corps together with the 4th Army crossed the Wkra river and advanced towards the town of Wloclawek. The 15th and 3rd Armies were approaching Modlin fortress and the 16th Army moved towards Warsaw. The final Soviet assault on Warsaw began on August 12 with the Soviet 16th Army commencing the attack at the town of Radzymin (only 23 kilometres east of the city). Its initial success prompted Pilsudski to move up his plans by 24 hours.
The first phase of the battle started on August 13, with a Red Army frontal assault on the Praga bridgehead. In heavy fighting, Radzymin changed hands several times and foreign diplomats, with the exception of British and Vatican ambassadors, hastily left Warsaw. On August 14, Radzymin fell to the Red Army, and the lines of Gen. Wladyslaw Sikorski's Polish 5th Army were broken. The 5th Army had to fight three Soviet armies at once: the 3rd, 4th and 15th. The Modlin sector was reinforced with reserves (the Siberian Brigade, and Gen. Franciszek Krajowski's fresh 18th Infantry Division—both elite, battle-tested units), and the 5th Army held out until dawn.
The situation was saved around midnight when the 203rd Uhlan Regiment managed to break through the Bolshevik lines and destroy the radio station of A.D. Shuvayev's Soviet 4th Army. The latter unit had only one remaining radio station fixed on one frequency which was known to the Polish intelligence. Since the Polish code-breakers did not want the Bolsheviks to find out that their codes were broken, but still neutralize the other radio station, the radio station in Warsaw recited the Book of Genesis in Polish and Latin on the frequency used by the 4th Army. It thus lost contact with its headquarters and continued marching toward Torun and Plock, unaware of Tukhachevski's order to turn south. The raid by the 203rd Uhlans is sometimes referred to as "the Miracle of Ciechanów."
At the same time, the Polish 1st Army under Gen. Franciszek Latinik resisted a direct Red Army assault on Warsaw by six rifle divisions. The struggle for control of Radzymin forced Gen. Józef Haller, commander of the Polish Northern Front, to start the 5th Army's counterattack earlier than planned.
During this time, Pilsudski was finishing his plans for the counter-offensive. He decided to personally supervise the attack and, because of the enormous risks involved, he handed in a letter of resignation from all state functions. Thereafter, between August 13 and August 15, he visited all units of the 4th Army concentrating near Pulawy, about 100 kilometres south of Warsaw. He tried to raise morale, since many soldiers were tired and demoralized and numerous recently incorporated replacements revealed the extent of Polish losses. Logistics were a nightmare, as the Polish army was equipped with guns made in five countries and rifles manufactured in six, each of them using different ammunition. Adding to the problem was the fact that the equipment was in poor shape. Pilsudski remembers: "In 21 Division, almost half of the soldiers paraded in front of me barefoot." Nevertheless, in only three days, Pilsudski was able to raise the morale of his troops and motivate them for one of their greatest efforts.
Second phaseThe 27th Infantry Division of the Red Army managed to reach the village of Izabelin, 13 kilometres from the capital, but this was the closest that Russian forces would come. Soon the tides of battle would change.
Tukhachevski, certain that all was going according to plan, was actually falling into Pilsudski's trap. The Russian march across the Vistula in the north was striking into an operational vacuum, where there was no sizeable group of Polish troops. On the other hand, south of Warsaw, Tukhachevski left only token forces to guard the vital link between the North-Western and South-Western Fronts. The Mozyr Group, which was assigned this task, numbered only 8,000 soldiers. Another error neutralized the 1st Cavalry Army of Semyon Budyonny, a unit much feared by Pilsudski and other Polish commanders. Soviet High Command, at Tukhachevski's insistence, ordered the 1st Cavalry Army to march toward Warsaw from the south. Semyon Budyonny did not obey this order due to a grudge between commanding South-Western Front generals Aleksandr Yegorov and Tukhachevski. In addition, the political games of Joseph Stalin, at the time the chief political commissar of the South-Western Front, further contributed to Yegorov's and Budyonny's disobedience. Stalin, in search of personal glory, wanted to capture the besieged, important industrial center of Lwów. Ultimately, Budyonny's forces marched on Lwow instead of Warsaw and thus missed the battle.
The Polish 5th Army counter-attacked on August 14, crossing the Wkra River. It faced the combined forces of the Soviet 3rd and 15th Armies (both numerically and technically superior). The struggle at Nasielsk lasted until August 15 and resulted in the almost complete destruction of the town. However, the Soviet advance toward Warsaw and Modlin was halted at the end of August 15 and on that day Polish forces recaptured Radzymin, which boosted the Polish morale.
From that moment on, Gen. Sikorski's 5th Army pushed exhausted Soviet units away from Warsaw, in an almost blitzkrieg-like operation. Sikorski's units, supported by the majority of the small number of Polish tanks, armoured cars and artillery of the two armoured trains, advanced at the speed of 30 kilometres a day, soon destroying any Soviet hopes for completing their "enveloping" manoeuvre in the north.
Third phaseOn August 16, the Polish Reserve Army commanded by Józef Pilsudski began its march north from the Wieprz River. It faced the Mozyr Group, a Soviet corps that had defeated the Poles during the Kyiv operation several months earlier. However, during its pursuit of the retreating Polish armies, the Mozyr Group had lost most of its forces and been reduced to a mere two divisions covering a 150-kilometre front-line on the left flank of the Soviet 16th Army. On the first day of the counter-offensive, only one of the five Polish divisions reported any sort of opposition, while the remaining four, supported by a cavalry brigade, managed to push north 45 kilometres unopposed. When evening fell, the town of Wlodawa had been liberated, and the communication and supply lines of the Soviet 16th Army had been cut. Even Pilsudski was surprised by the extent of these early successes. Reserve Army units covered about 70 kilometres in 36 hours, splitting the Soviet offensive and meeting virtually no resistance. The Mozyr Group consisted solely of the 57th Infantry Division, which had been beaten in the first day of the operation. Consequently, the Polish armies found a huge gap between the Russian fronts and exploited it, continuing their northward offensive with two armies following and falling on the surprised and confused enemy.
On August 18, Mikhail Tukhachevski, in his headquarters in Minsk some 300 miles (500 km) east of Warsaw, became fully aware of the extent of his defeat and ordered the remnants of his forces to retreat and regroup. His intention was to straighten the front line, stop the Polish attack and to regain the initiative, but the orders either arrived too late or failed to arrive at all. Soviet General Gay's 3rd Cavalry Corps continued to advance toward Pomerania, its lines endangered by the Polish 5th Army, which had finally managed to push back the Bolshevik armies and gone over in pursuit. The Polish 1st Division of the Legion, in order to cut the enemy's retreat, made a remarkable march from Lubartów to Bialystok - 163 miles (262 km) in 6 days. The soldiers fought in two battles, slept only a few hours and marched for up to 21 hours a day. Their sacrifice and endurance was rewarded when the entire 16th Soviet Army was cut off at Bialystok and most of its troops taken prisoner.
The Soviet armies in the centre of the front fell into chaos. Some divisions continued to fight their way toward Warsaw, while others turned to retreat, lost their cohesion and panicked. The Russian commander-in-chief lost contact with most of his forces, and all Soviet plans were thrown into disorder. Only the 15th Army remained an organised force and tried to obey Tukhachevski's orders, shielding the withdrawal of the westernmost extended 4th Army. But it was defeated twice on August 19 and 20th and joined the general rout of the Red Army's North-Western Front. Tukhachevski had no choice but to order a full retreat toward the Western Bug River. By August 21, all organized resistance ceased to exist and by August 31, the Soviet South-Western Front was completely routed.
AftermathAlthough Poland managed to achieve victory and push back the Russians, Pilsudski's plan to outmaneuver and surround the Red Army did not succeed completely. Four Soviet armies began to march toward Warsaw on July 4 in the framework of the North-Western Front. By the end of August, the 4th and 15th Armies were defeated in the field, their remnants crossed the Prussian border and were disarmed. Nevertheless, these troops were soon released and fought against Poland again. The 3rd Army retreated east so quickly that Polish troops could not catch up with them; consequently, this army sustained the fewest losses. The 16th Army disintegrated at Bialystok and most of its soldiers became prisoners of war. The majority of Gay's 3rd Cavalry Corps were forced across the German border and were temporarily interned in East Prussia.
Soviet losses were about 15,000 dead, 500 missing, 10,000 wounded and 65,000 captured, compared to Polish losses of approximately 4,500 killed, 22,000 wounded and 10,000 missing. Between 25,000 and 30,000 Soviet troops managed to reach the borders of Germany. After crossing into East Prussia, they were briefly interned, then allowed to leave with their arms and equipment. Poland captured about 231 pieces of artillery and 1,023 machine-guns.
The southern arm of the Red Army's forces had been routed and no longer posed a threat to the Poles. Semyon Budyonny's 1st Cavalry Army besieging Lwów had been defeated at the Battle of Komarów and the Battle of Hrubieszów. By mid-October, the Polish Army had reached the Tarnopol-Dubno-Minsk-Drisa line.
Tukhachevski managed to reorganize the eastward-retreating forces and in September established a new defensive line near Grodno. In order to break it, the Polish Army fought the Battle of the Niemen River (September 15–September 21), once again defeating the Bolshevik armies. After the Battle of the Szczara River, both sides were exhausted and on October 12, under heavy pressure from France and Britain, a cease-fire was signed. By October 18, the fighting was over, and on March 18, 1921, the Treaty of Riga was signed, ending hostilities.
Soviet propaganda before the Battle of Warsaw had described the fall of Poland's capital as imminent, and the anticipated fall of Warsaw was to be a signal for the start of a large-scale communist revolutions in Poland, Germany and other European countries, economically devastated by the First World War. The Soviet defeat was therefore considered a setback for some Soviet officials (particularly Vladimir Lenin).
A National Democrat Sejm deputy, Stanislaw Stronski, coined the phrase, "Miracle at the Wisla", to underline his disapproval of Pilsudski's "Ukrainian adventure." Stronski's phrase was adopted with approval by some patriotically- or piously-minded Poles unaware of Stronski's ironic intent.
Breaking of Soviet ciphersAccording to documents found in 2005 at Poland's Central Military Archives, Polish cryptologists broke intercepted Russian ciphers as early as September 1919. At least some of the Polish victories, not only the Battle of Warsaw but throughout the campaign, are attributable to this. Lieutenant Jan Kowalewski, credited with the original breakthrough, received the order of Virtuti Militari in 1921.
Orders of battlePolish3 Fronts (Northern, Central, Southern), 7 Armies, a total of 32 divisions: 46,000 infantry; 2,000 cavalry; 730 machine guns; 192 artillery batteries; and several units of (mostly FT-17) tanks.
Fronts:
- Northern Front: 250 km., from East Prussia, along the Vistula River, to Modlin:
- Central Front:
- Southern Front - between Brody and the Dniestr River
