Łyżwiński. The retreating Soviet forces managed to break through, but suffered heavy casualties. By the end of the day, the battle was over. Results and casualties The Polish 1st Cavalry Division then pursued the retreating Soviets. The forces of Budyonny managed to break through Polish lines, but the Poles did not leave them enough time to rest and reorganise. On 2 September the Polish VI Cavalry Brigade reached Łaszczów, where it successfully outflanked the Soviet 44th Rifle Division and annihilated one of its regiments (only 100 POWs survived the battle). The 1st Cavalry Army itself was not surrounded and managed to avoid complete destruction, but it no longer posed a threat to the advancing Poles. Unable to regroup, on 5 September 1920 it lost the town of Hrubieszów, and Włodzimierz Wołyński the following day. On 12 September 1920, Polish forces withdrawn from the Battle of the Niemen under General Władysław Sikorski started a successful offensive on Soviet-held Volhynia. Pressed from all directions, the 1st Cavalry Army lost Równe on 18 September and was forced to retreat further eastwards. By the end of September, the Polish forces reached the Słucza River, near the lines held by the Soviets before their offensive towards Warsaw started. Soon afterwards, Budyonny's Army had to be withdrawn from the front, not to return until after the cease fire that October. The Battle of Komarów was a disaster for the Russian 1st Cavalry Army. Numerically greatly superior, it failed to concentrate and act as an organised unit, which resulted in several consecutive waves of attacks, each of them repelled by the Polish forces. A lack of communication and disregard for intelligence reports resulted in heavy losses on the Russian side. After the battle, its political commissars, Joseph Stalin and Kliment Voroshilov, failed to control the men in their command: with morale and discipline at a low point, robbery and violence by the 'Red Cossacks' against the civilian population became commonplace. The 1st Cavalry Army also became known for periodic outbreaks of murderous anti-semitism. The Polish Army lost approximately 500 killed in action and 700 horses. No Poles were taken prisoner by the Red Army. The exact losses of the latter were never made public and are unknown. Because of the numbers of forces involved, the Battle of Komarów is considered the greatest cavalry battle of the 20th century. It is sometimes referred to as "the greatest cavalry
