Nonetheless, Sweden now controlled almost all the Baltic's ports; with the notable exceptions of Danzig, Putzig, Königsberg and Liepāja (Libau). This would be the closest the Swedes ever got to realising their goal of making the Baltic Sea 'Sweden's inner lake'. After the treaty, Sweden used their prizes and money as a starting point for their entry into the Thirty Years' War and commenced the invasion of northern Germany. The Treaty of Altmark was eventually revised in the Commonwealth's favour in 1635 (Treaty of Sztumska Wieś or Treaty of Stuhmsdorf), when Sweden, with the death of the king Gustav Adolph in 1632, was weakened by its losses in the Thirty Years' War, retreated from some of the Baltic ports and stopped collecting the 3.5% tax.
