100 years ago, in September 1920, Polish troops again defeated the armies of the Western Front under the command of Tukhachevsky. The dream of a "red Warsaw" had to be abandoned. Moscow abandoned its initial demands on Warsaw and went to a "bawdy" peace, yielding Western Ukraine and Western Belarus to the Poles, and also paid an indemnity to Poland.
After the Vistula disaster
After a heavy defeat on the Vistula, Tukhachevsky's troops by August 25, 1920 stopped on the line Augustow - Lipsk - Kuznitsa - Visloch - Belovezh - Zhabinka - Opalin. The northern part of the front ran west of the Neman and Shchara rivers. The Poles, despite the heavy defeat of the Russian troops, also stopped. Communications in this area were destroyed, it was necessary to tighten up the rear, restore railways and bridges, replenish units and establish supplies. The strike of the Polish army aimed from south to north with access to the Prussian border in order to cut off the strike group of the Western Front has exhausted itself. It was necessary to regroup the troops, it took time. At the same time, the Poles retained the initiative and prepared to continue the offensive. The Polish army consisted of about 120 thousand soldiers, over 800 guns and 2500 machine guns.
The Soviet troops were even more exhausted. The victorious battles in Byelorussia, the campaign against Warsaw, the defeat on the Vistula and the retreat, often chaotic, bled the Western Front. Tukhachevsky's armies lost most of the soldiers (mainly prisoners and internees), materiel, and artillery. It was necessary to reorganize and replenish the units, supply them with weapons, ammunition, equipment, etc. The Soviet command took urgent measures to replenish the greatly thinned troops on the front line. The rear units and institutions were disbanded, which had grown greatly, their personnel were sent to combat units. In early September, the remnants of the broken Soviet units, which were making their way to the east through forests, far from the main roads, reached their own. It was necessary to bring them to their senses, arm them, equip them, return them to their units or include them in others. It was also necessary to build fortifications on the new lines of defense. Then up to 30 thousand people returned to the Western Front, who were interned in Germany. The front mobilized in the rear areas.
As a result, Tukhachevsky was able to almost completely restore the combat strength of the front (although its quality was worse). The western front included 6 armies (3rd, 15th, 16th, 4th, 12th and 1st Cavalry), 18 rifle, 4 cavalry divisions, 1 rifle and 4 cavalry brigades. In total, these troops numbered about 95 thousand bayonets and sabers, about 450 guns and 2 thousand machine guns. The 4th Army was restored, most of whose troops fled to the territory of East Prussia. The management of the 4th Army, which had lost its troops, took the lead in the Mozyr group. The 4th Army became the front reserve.
The plans of the Soviet command
The Soviet leadership believed that in connection with the failures on the Western and Southwestern Fronts, it was necessary to abandon the plans for Sovietization of Poland and eliminate the threat from the south before the onset of winter. Destroy the White Guards in Northern Tavria and Crimea. The seat of the White Army in Crimea was very dangerous, since at that time a new wave of peasant war began throughout Russia. Therefore, on September 21, 1920, the Southern Front was re-formed. Since September 27 it has been headed by the famous Soviet statesman and commander Mikhail Frunze. The best divisions were sent to the Southern Front. It was replenished first. On September 26, they were withdrawn to the reserve and then sent to the Southern Front and the 1st Cavalry Army of Budyonny. The southern front received two strong mobile formations: the 1st and 2nd Cavalry armies. As a result, the Western Front lost its paramount importance for Moscow.
The military command, despite the catastrophe that occurred (based on the errors of the command), believed that the troops could still return the strategic initiative and take Warsaw. Tukhachevsky was eager for revenge. At the first stage of the offensive, the Red Army was supposed to return Brest and Bialystok, defeat the opposing Polish troops and develop an offensive on Lublin and Warsaw. It was proposed to again throw the troops of the 12th, 14th and 1st Cavalry armies on Lvov, pulling the Polish forces from the Warsaw direction to the south. Meanwhile, the right wing of the Western Front will again launch an offensive against Warsaw. However, the commander-in-chief of the armed forces of the Soviet Republic, Sergei Kamenev, was against the new adventure. He was against the involvement of Budyonny's army in the battle for Lvov and demanded to leave it in the Grubieszow area in order to threaten with a strike on Lublin. It is also worth considering that in the battles in the region of the Lviv fortified region and in the battle of Komarov, the cavalry divisions suffered serious losses, were physically and financially exhausted. Only about 8 thousand horsemen remained in the 1st Cavalry Army. In addition, the Polish 3rd Army, supported by part of the 4th Army forces, defeated the Soviet 12th Army on September 1–6. Soviet troops pushed back to the east of the river. Western Bug south of Brest-Litovsk.
However, Kamenev and Tukhachevsky believed that these enemy successes were temporary. That most of the Polish army is concentrated on the southern flank and the Poles will not be able to fend off a powerful blow in the north. On the northern flank of the Western Front there were 3 armies (3rd, 15th and 16th), up to 14 divisions. A new offensive was planned for November. Intelligence reported that the enemy was tired of fighting and was not preparing a new major offensive. The intelligence and command of the Western Front were wrong. The Poles were ready for a new battle and rushed forward.
The 3rd Soviet Army under the command of Lazarevich covered the Grodno direction. It consisted of 24 thousand people and more than 70 guns. The 15th Army of Kork covered the Bridges on the Neman and Volkovysk. It consisted of 16 thousand soldiers, more than 80 guns. The 16th Army of Sollogub (from September 21, the troops were led by Cook) defended the road to Slonim and Baranovichi. There were 16 thousand people in the army. In the south of Belarus, in Polesie, the newly created 4th Army of Shuvaev was stationed. Its divisions numbered over 17 thousand people.
On Grodno
The Polish command was preparing a new offensive in Belarus. On August 27, 1920, after the end of the battle on the Vistula, the Polish commander-in-chief Piłsudski ordered to regroup the troops of the 2nd and 4th armies of Rydz-Smigla and Skerski. He strove to end the war in Poland's favor. On September 10, at a meeting with the commanders of the 2nd and 4th armies, Pilsudski said that the main blow would be delivered in the Grodno-Volkovysk region. At the same time, a strike group was formed on the northern flank of the 2nd Army in order to march through Lithuanian territory to bypass the right flank of the Soviet front and, in the Lida region, go to the rear of the enemy. Further, the Reds were going to be thrown into the area of the Polessye swamps. Poland wanted to inflict a decisive defeat on Russia and move the eastern border beyond the "Curzon line".
On September 19, 1920, Pilsudski's order was issued with detailed tasks for all armies and groups. The 2nd Army of Rydz-Smigly (6 divisions, 2 cavalry brigades and a group of heavy artillery) aimed at Grodno. Heavy artillery was required to capture the Grodno fortress. The 2nd Army was the most powerful in the Polish Army: over 33 thousand people in combat units (about 100 thousand in total), 260 guns, about 1,000 machine guns, 16 armored cars, 18 aircraft, more than 350 vehicles. The Northern group of General Osinsky (former general of the tsarist army), consisting of the 17th division and the Siberian brigade, was allocated from the 2nd Army. The task force was to make a dash across Lithuania to the Lida area. Skersky's 4th Army advanced on Volkovysk and south of it. It consisted of 4 divisions, about 23 thousand people in combat units (more than 50 thousand in total), 170 guns, 18 armored cars and 5 aircraft. The soldiers were well armed and trained. The reserve of the Northern Front (2nd and 4th armies) had one infantry division and a cavalry brigade.
The Polish troops had some advantage in manpower in the direction of the main attacks. The qualitative composition of their armies was much better, as was the fighting spirit. The Polish soldiers were encouraged by their successes. The Red Army men were demoralized by the defeat. Among them there were many poorly trained recruits, peasants from the regions of Russia, engulfed in uprisings, that is, those who had weak stamina, motivation, and inclined to flee.
