In June, the RSFSR was finally ready to open its major Western advance. To preserve the neutrality of Lithuania (though the peace treaty was still being negotiated), on 6 June the exiled government of Litbel was disbanded. Within a few days, the 3rd Cavalry Corps under command of Hayk Bzhishkyan broke the Polish front, causing a collapse and a retreat. On 11 July Minsk was re-taken, and on 31 July 1920 once again the Soviet Socialist Republic of Belorussia was re-established in Minsk.
