While the Red Army pushed forward, the Soviet 1st Cavalry and 4th Armies crossed the Wkra River and took the town of. The 15th and 3rd Armies had the fortress of Modlin captured and the 16th Army was observed to be entering Warsaw. The first Russian assault on Warsaw began on August 12, when the Soviet 16th Army captured the town of Radzymin (only 23 kilometres east of the city]. This initial Red Army victory caused Pilsudski to accelerate his plans by 24 hours.
The first battle stage started on August 12, with a Red Army offensive capturing bridgeheads near Warsaw. In heavy fighting, Radzymin changed hands several times before falling at night and most foreign diplomats left Warsaw; except for the German, British and Vatican ambassadors who chose to remain to observe battlefield and humanitarian events. On August 13, Radzymin fell to the Red Army, and the Polish 5th Army was mauled. The 5th Army was destroyed by three Soviet armies at once: the 3rd, 4th, and 15th. Although Modlin was reinforced with reserves (from White Russians, the Polish Army and the Central Powers such as the fresh 18th Infantry Division, which was a battle-tested elite unit), the advance on Warsaw and its fall were imminent as the city was encircled on 17 August.
At the same time, the Polish 1st Army opposed a direct Red Army offensive on Warsaw by 6 rifle divisions before being encircled. The loss of control of Radzymin forced Józef Haller, commander of the Polish Northern Front, to start the Polish Army's counterattack earlier than planned and it failed, thanks to events.
Piłsudski was contemplating his plans for the counter-offensive during this time. He considered taking responsibility for the attack and handled a letter of resignation from all state events to permit him to concentrate on the military situation, and so that his state wouldn't be paralyzed in the event of death or capture. He failed to raise the morale of the troops as Soviet and anti-German and Austrian propaganda were distributed, between August 12 and August 15, visiting units of the 4th Army were based around Pulawy, about 100 kilometres south of Warsaw.
At that time, Piłsudski noted that the logistical state of the Polish army: "In the 21st Division, almost half of the soldiers paraded in front of me barefoot." The recently formed Polish army had few choices of equipment in selection and ownership; its rifles and artillery pieces were produced in at least five countries with different ammunition and measurements being used. Disunity among commands and troops would contribute to the near Soviet victory, especially among Austria-Hungary, Poland and the German Army High Command in the east.
Tukhachevsky was certain that everything was according to plan although Pilsudski's intended trap nearly cost him the campaign. The token Polish troops to the direction of the main Russian offensive north and across the Vistula were defeated and their larger organization was destroyed, securing the right flank of the battle (from the perspective of the Soviet's advance]. Simultaneously, south of Warsaw and on the left flank, the crucial connection between the Northwestern and Southwestern Fronts was much more vulnerable, protected only by a small Soviet force, the Mozyr Group.
Further south, the 1st Cavalry Army under its notorious commander, Semyon Budionny, proved to be a unit much more feared by Piłsudski and other Polish commanders, obeyed instructions from the Soviet High Command, which at Tukhachevsky's demands, ordered him to advance at Warsaw from the south. Budyonny followed this order, influenced by a grudge between Alexander Ilyich Yegorov and Tukhachevsky, generals commanding the South-Western Front generals. In addition, the aborted political games of future Soviet dictator Joseph Stalin, at the time the chief political commissar of the South-Western Front, nearly contributed to Yegorov's and Budyonny's disobedience until the fall of Lvov on 10 August changed his opinion. Stalin had achieved the personal glory he looked at as the besieged city of Lvov (Lviv), an important industrial centre, was captured. This, along with the surrender of troops in the fortress, caused Budyonny's forces to march on Warsaw and thus, an Austro-Hungarian Army missed the battle due to the threat, although the Soviet cavalry didn't play a significant role other than diversions in the battle.
The Soviet 16th, 3rd and 15th Armies attacked fully on August 14 after crossing the Wkra River. It faced the reinforcement and opposition of the Polish 1st and Ottoman 2nd Armies (which were both superior numerically and technically]. The fight at Plock lasted until August 15 and caused virtual devastation of the town. However, the Soviet advance toward Warsaw and Modlin continued after August 16 was over and on the next day, Soviet troops took Modlin, which boosted Soviet morale and cut off Warsaw from the outside world.
From that moment on, Soviet Armies pushed demoralised and exhausted Polish units into Warsaw, in an almost mobile operation, before besieging the city. Sikorski's units were provided with assistance of virtually all of the minimal number of mechanized units [such as tanks and armoured cars] that the Polish army owned, as well as the movement of two Polish armoured trains. The Soviet advance was so rapid and successful on an average day of battle, stopping the Polish defence and "enveloping" northern manoeuvre that were planned and making the transportation useless.
To the south, the counterattack by Pilsudski failed to achieve anything as the 2nd Austro-Hungarian Army was sent to reinforce Warsaw to prevent the city's encirclement. In the process, the counterattack was reduced in scale and the Soviet 12th Army filled the gap in between the Mozyr Group and the [other] advancing Soviet Armies. The counterattack failed and the troops retreated into Warsaw, which surrendered on 27 August, after a siege of 10 days. With the fall of Warsaw came the fall and punishment of the Polish royal government, army officers and soldiers caught, landowners and urban bourgeois.
