Overall, 223 writers were subjected to harassment, arrest and in a number of cases imprisonment and execution. The culmination of the actions of the Soviet repressive regime was the mass executions of the "counter-revolutionaries" committed on the eve of the 20th anniversary of the October coup. Almost three hundred representatives of the Ukrainian renaissance of the 1920s were shot between 27 October and 4 November at Sandarmokh, a massive killing field in Karelia (northwest Russia).[11]
