 and in the Belarussian SSR. The Red Army totaled 5,000,000, with additional millions of Russian recruits to draw from, but much of that force was still engaged in the civil war. This number of troops was far greater than the number of weapons available, and only one in nine soldiers could be properly classified a fighting man. In the course of 1920, almost 800,000 Red Army personnel were sent to fight in the Polish war, of whom 402,000 went to the Western front and 355,000 to the armies of the South-West front in Galicia. The Soviet manpower pool in the West was estimated at 790,000. The Soviets had at their disposal much military equipment left by withdrawing German armies, and modern Allied armaments (including armoured cars, armoured train

The Polish forces grew from approximately 100,000 in 1918 to over 500,000 in early 1920. In 20 August 1920, Polish army had reached the strength of 737,767, so there was rough numerical parity between the Polish army and the Soviet forces acting against it. Polish intelligence was aware that Soviets have been prepared for a new offensive and Polish High Command decided to launch their own offensive before the Soviets. The plan for Operation Kiev was more ambitious then simply to defeat the Red Army on Poland's southern flank. It aimed at creating a friendly government on the captured Ukrainian territories. Afterwards, the Piłsudski and Polish General Staff planned to reassign the 3rd Army to the north, where Polish planners expected a major Red Army's counteroffensive.

 (Soviet May Offensive). The Soviet Southwest Front was commanded by Alexander Ilyich Yegorov. On 15 May the Soviet 15th Army attacked Polish positions near Ułła, and the 16th Army crossed the Berezina River between Borysów and Bobrujsk. Polish forces in that area, preparing for an offensive towards Żłobin, managed to push the Soviet forces back into the river, but were unable to pursue their own planned offensive. In the north Polish forces had done much worse. The Polish 1st Army was defeated and started a retreat towards Mołodeczno, pursued by the 15th army which had recaptured the territory between Dzwina and Berezyna.

Polish forces attempted to take advantage of the exposed Soviet flanks, Armia Rezerwowa attacking from Święciany and Grupa Skierskiego attacking from Borysów were supposed to envelope and crush the advancing Soviet forces, and Soviet reinforcements be stopped by the 1st Army. This time the 1st Army did better but the enveloping forces still failed to stop the Soviet advance. By the end of May, the front had stabilised near the small river of Auta, and Soviet forces begun preparing for their next push, concentrating in the Połosck region.
On May 24, 1920, the Polish–Ukrainian forces in the south clashed with the Semyon Budionny's famous 1st Cavalry Army

. The Polish 3rd army in Kiev faced the danger of being completely enveloped.

It was a bitter day for the Poles and Ukrainians when, on June 13, they abandoned Kiev to the Bolsheviks. The small group of Petlyura's Ukrainians did not lose their morale and fought with determination throughout the rest of the war. In the face of near-unlimited Russian reserves and slow growth of the Ukrainian Army, the Polish and Ukrainian forces were ordered to retreat.

Bolshevik victories

The commander of the Polish 3rd Army in Ukraine, General Rydz-Śmigły, decided to break through toward the northwest and the town of Korosteń, thus avoiding a direct confrontation with the bulk of Soviet 1st Cavalry Army near Koziatyń. Soviet forces were plagued by communication and coordination difficulties, and Polish forces managed to withdraw in orderly fashion and relatively unscathed, they were tied down in Ukraine and lacked sufficient strength to support Poland's Northern Front and reinforce the defenses at the Auta River for the decisive battle that was soon to take place there. Polish 3rd Army and newly formed 2nd Army regrouped near Słucza and started a series of their own counterattacks. However, Polish counterattacks in June and July all failed after initial successes. In the battles (19 June at Usza, 1 July at Horyń, 8 July at Równe) Bolsheviks were delayed but eventually Budionny's forces advanced east. When eventually in mid July Bolsheviks forces in Ukraine appeared to have been stopped by Polish forces, a new Soviet offensive north would prove even more devastating for the Polish forces.

Poland's 200-mile-long front was manned by a thin line of 120,000 troops of the 1st and 4th Armies and Group Polesie. Logistics were a problem, and the force had inadequate support of only 460 artillery pieces. Gen. Szeptycki, commander of the Polish Northeast Front, had no strategic reserves, and some forces have been shuffled south to stop the Soviet offensive in Ukraine and Galicia. This approach to holding ground harked back to Great War practice of "establishing a fortified line of defense." Where it was a viable strategy on the Western Front, where each inch was saturated with troops, machine guns and artillery, the spacious fields of the Eastern Front would require a much larger force then those fielded by the Allies and the Central Powers in the West. Piłsudski tried to formulate a newe strategy of "strategie de plein air" (French: a "strategy of open space") rather than to try to tie his insufficient forces to mostly inexistant fixed positions, but his suggestions were not met with approval of other commanding officers. Meanwhile, the Red Army's Northwest Front was commanded by the young General Mikhail Tukhachevski. Tukhachevski forces of 108,000 infantry and 11,000 cavalry, supported by 722 artillery pieces and 2,913 machine guns were divided into one cavalry corps and four armies: the 3rd cavalry and 4th, 15th, 3rd and 16th armies, deployed respectively from north to south. With the advantage of being able to plan their offensive, crucially, the Russians were able to achieve a four-to-one force advantage in the planned break-through points.

The northern 3rd Cavalry Corps of Gej-Chan was to envelope Polish forces from the north, moving near Lithuanian and Prussian border territories, both unfriendly to Poland. 4th, 15th and 3rd Armies were to push decisively west, supported from south by the 16th Army and Grupa Mozyrska. For the three days the Polish forces hed, yet despite local victories, such as when two battalions of the Polish 33rd Infantry Regiment, held the advance of two and a half Red Army divisions for a full day, securing the northern flank of the Polish front the Russians' numerical superiority eventually won them the day. Tukhachevski's plan to break through and push the southwest Polish units into the Pinsk Marshes

 (Błota Poleskie) failed, but the northern theatre proven to be his decisive victory. Gej-Chan broke through the northern Polish units on the first day of the offensive and Polish 1st Army pursued by Gej-Chan forces started a disorganised retreat. From July 7 the Polish forces were in full retreat on the entire front.

Poles attempted to regroup at the heavily fortified line of German World War I field fortifications. The "Battle for Wilno" took place here from July 11 to July 14. Once again, however, the Polish troops were unabe to man the whole front, and Soviet forces broke through one of the weak points in the north. Gej-Chan forces, supported by Lithuanian forces, captured Wilno on 14 July, making Polish plans for defensive along old German trenches useless. On 19 July Grodno fell and after a failed Polish counterattack towards Grodno the 1st Army had to retreat behind Neman River

. In early July it became clear to the Poles that the Russians' objectives were not limited to pushing their borders farther west. Poland's very independence was at stake.

The Russian forces advanced rapidly at a rate of 20 miles a day; shocking many commanders and foreign observers who were expecting a repeat of the Western snail paced advance.

Polish attempt to defend the Bug River line with 4th Army and Grupa Poleska units stopped the advance of the Red Army for only one week. The Red Army advance slowed down – but only to 12 miles a day. Units of the Russian Northwest Front, after taking Łomża and Ostrołęka (by Gej-Chan) and crossing the Narew River on August 2, approached the 60 miles radius from Warsaw. Fortress of Brześć which was to be the headquarters of Polish planned counteroffensive fell to the 16th Army in the first attack.

Polish forces in Galicia near Lwów launched a counteroffensive to slow the Soviets down. The 6th Army of general Jędrzejewski and elements of the Ukrainian forces defended Lwów, and the 2nd Army and Grupa Operacyjna Jazdy attacked from Styr towards Brody and Radziwiłłów, Masovian Voivodeship. During the battle of Brody (29 July – 2 August) Polish forces managed to recapture Brody (18 Dywizja Piechoty) and surround parts of Soviets forces. This had put a stop to the retreat of Polish forces on the southern front, but the worsening situation near Polish capital of Warsaw prevented Poles from continuing that southern counteroffensive and pushing east. After Soviets captured Brześć, the Polish offensive in the south was put on hold and all available forces moved north to take part in the coming battle for Warsaw.

Weygand had traveled to Warsaw in the expectation of assuming command of the Polish Army, but had found a disappointing reception, aggravated by the fact that around the same time France have frozen its financial aid to Poland. His first meeting with Piłsudski on July 24 began on the wrong foot when he had no answer to Piłsudski's opening question, "How many divisions have you brought?" Weygand had none to offer. On 27 July he was installed as adviser to the Polish Chief of Staff, Tadeusz Rozwadowski, but their collaboration went poorly. He was treated with contempt by many Polish officers, his suggestions were regularly disregarded. One of the few officers who treated him fairly was General ładysław Sikorski. After a while, he threatened to leave, which he did shortly after the Polish victory at Warsaw. Before departing on August 25 he was consoled with the decoration of Virtuti Militari
