The king's plan never had strong support from Polish nobles (szlachta): high costs and reluctance to strengthen the king's power were always crippling Władysław's plans. Thus not even all the king's expenses for the modernization of those ten ships were fully repaid. Unfortunate international alliances (with Denmark and Muscovy) did not allow him to mount any offensive actions and the majority of the wars he participated in were defensive ones (like the Smolensk War with Muscovy in 1634). A new armistice with Sweden signed in Stumsdorf (Sztumska Wies) knocked the last argument out of the king's hand. After that the king wanted to use his ships to organize the first Polish merchant company (with help of Hewel), however Hewel's death stopped even those plans. Finally the ships were sold. The built fortifications were salt in Denmark's and the Danzig Patriciate eyes and under their pressure were destroyed in 1640s.
