On hearing of Winckelbruch's advance, hetman Zborowski marched all but 100 infantry out of Tczew to attack the Gdansk army, crossing the Motława River (a tributary of the Vistula then swollen with the spring thaw) at Rokitki, while Winckelbruch sent a force of 200 to delay the Commonwealth army as he tried to flank it and cross the Motława between two lakes to the south of the town of Lubieszów itself, west south west of Rokitki.
