A group of envoys from Brandenburg, Prussia, and Mecklenburg shuttled back and forth between Duke Charles's and Sigismund's camps for three weeks, trying to rescue the peace. Despite their great efforts, they failed. Sigismund sailed with his infantry to Stegeborg Castle on August 11. The cavalry went to the same place by land. Charles's situation was hardly optimal. The only bright spots were the escapement of , the ex-commander of Stockholm, from the city, and the Swedish navy's refusal to join forces with the Poles.
