The Cossack Vasiliy Romanovskiy and his partner Cossack Yakov Sinenko traveled to Crimea for trade on five cargo carts. In Kamianoy backwater, ten Janissaries attacked them. Between the Janissaries were two famous Ali and Hasan. The Janissaries forced them to sell five carts loaded with butter for half the price the Cossacks refused. The Janissaries beat the Cossack Sinenko half to death and threatened the Cossack Romanovskiy with beatings upon his arrival in the Crimea. When Romanovskiy arrived in Perekop, he was beaten by janissary Benderniy at the urging of janissaries Ali and Hasan.
