The rest was interrupted again when Charles X Gustav declared war against Poland in 1655. Under Daniel Jonsson's command, the company marched from Mora to Stockholm for further sailing towards Wolgast. On July 15 the destination was reached and followed by the march towards Warsaw via Szczecin. The battle was bloody and Dalarna Regiment lost 182 men. If Daniel Jonsson was wounded is not known, but in 1656 he was granted leave as head of Mora kompani.
