This text discusses the visit of Stefan Żeromski, Jan Kasprowicz and Władysław Kozicki to Powiśle in May and June 1920. The last weeks of the plebiscite campaign urged Stefan Dąbrowski – the undersecretary of state in the Ministry of Foreign Affairs – to undertake actions that on the one hand would support Poles before the vote, and on the other hand publicize the plebiscite in Poland. The article attempts to reconstruct the chronology of the trip taken by the writers, as well as their actions and meetings in the territory of West Prussian Plebiscite Region with the main seat in Kwidzyn. Most research has been so far based on a narrative by Stefan Żeromski entitled Inter Arma. However, interviews and press publications issued after the writers left Powiśle broaden our knowledge of the 1920 events by new facts.
