"Before 1655, all cases of treason were severely punished. After the meeting with Swedes, where a group act of treason took place, its participants were not condemned. Furthermore, they were later allowed to return to Poland, and to participate in public life (...) It was after Ujście that collaboration and treason emerged as one of possible choices in the so-called "decent families". It was not only the Swedish invasion in itself that undermined Polish statehood. It also was the weed of treason, which was allowed to take root and with which we still struggle".Zaczęło się pod Ujściem – dr Piotr Naimski o zdradzie narodowej.
