Nikolayevsk Incident
Triapitsyn decided to terrorize and kill any civilians he felt were a danger to his forces. The other way to execute those who he only injured was to stab them with a bayonet and throw them into a hole in the Amur River. Using this method, Triapitsyn and his army killed thousands of people in Nikolayevsk-on-Amur. In late May, as other Japanese people were coming to help, Triapitsyn killed everyone living in Nikolayevsk-on-Amur–Japanese or Russian–and burned the town to the ground.
