the time of the Bolshevik takeover of Russia in November 1917, Piasecki at age sixteen, found himself in Moscow. He saw with his own eyes the barbarity of the Bolshevik revolution, and from then on, became an avid anti-Communist. Some time in 1918 or 1919, he returned to Belarus, joining the Belarusian anti-Soviet units called Zialony Dub ("Green Oak"), led by ataman Wiaczeslaw Adamowicz.
