On February 1, Grigoriev entered into negotiations with the Soviet troops – he established contact with the chief of staff of the Special Group of Soviet Forces Petrenko, stating that he was negotiating on behalf of the Borotbist Central Revolutionary Committee. Grigoriev stated that he had twenty partisan detachments at his disposal, ready to fight against the Petliurists, White Guards, Germans and interventionists. The Ataman also had a telephone conversation with Antonov-Ovseyenko. During the negotiations, he agreed to submit to the command of the Red Army, as well as to recognize the Council of People's Commissars of the Ukrainian SSR – thereby, he actually renounced the Borotbist Tsentrrevkom.
