When Erik Dahlbergh retired in early 1702 he was replaced by Lieutenant General Carl Gustaf Frölich (1637-1714), a highly original and very colourful man. On the positive side it could perhaps be said that he wasn't afraid of taking the initiative and always was prepared to offer suggestions on how to solve difficult problems, but in some cases his methods and proposals bordered on the bizarre. In the summer of 1711 Frölich suggested that a native Swede should be sent to the Danish king with the message that "the evil spirit" had inspired him to make war on Sweden and a couple of months later he offered to transport an army to Zealand without using any ships. In December 1711 Frölich stated that the plague could be stopped by prayers and juice from juniper berries, which was "a wonderful thing for both internal and external use".
Frölich is more perhaps more famous for the innovative monetary reform he carried out in late 1705. Without any sort of authorization from Charles XII he on 5 December 1705 issued a proclamation concerning "doppelte, eintzele und halbe Carolinen auch die fünff Oehr-Stücke". They should be handed in to a committee appointed by Frölich (Captain Daniel Leijonancker, the commissioner Johan Hilleboldt and Lieutenant Johan Wilhelm Max). The idea behind seems to have been that people would only receive half of their coins in return, but these would after stamping be worth twice their original value so nobody would (in theory) lose anything. Needless to say Frölich's actions did not appeal to Charles XII, who shortly dismissed him and sent an angry letter ordering the immediate abolishment of the monetary reform.
