It has frequently been claimed that Charles XII never forgave Magnus Stenbock for the surrender in 1713 and took his revenge by letting his old favorite remain a prisoner of war in Denmark. The evidence is slim. Not only did Charles XII on 12 August 1713 order the Council to prepare a new transport to Germany. Stenbock would be in command (the King assumed that the prisoners had been released in accordance with the agreement made when the army surrendered).
An even clearer evidence is a letter from Casten Feif to Stenbock, dated Demotika 24 July 1714. Feif assures the Field Marshal that he should not worry, the King continued to hold him in high regard. Stenbock should not, Charles had told Feif, listen to rumours who were intended to annoy him but rather take care of his health so that the King once more would have the joy of seeing his old friend as happy and amusing as he used to be.
