The KPRP opposed Poland's war against Soviet Russia of 1919–21. During the fighting, the KPRP's legal status was legislatively taken away; the communist party would remain an underground organization in Poland until its demise. Due to the support for the government provided by pro-independence socialists of the PPS, efforts by the KPRP to agitate for workers' solidarity with the Red Army were forestalled. However, at the height of the Red Army offensive the Provisional Polish Revolutionary Committee was formed on 2 August 1920. It consisted of Julian Marchlewski, Felix Dzerzhinsky, Feliks Kon, Józef Unszlicht, and Edward Próchniak. Its establishment brought no political gains for the party. The traditional Marxist position on the land question as understood by the Polish Marxists was abandoned, in favour of Vladimir Lenin's views.
