The allies decided that they would no longer make an exchange of prisoners. It was manifest that, by merely protracting the war, even without any signal successes on the part of the allies, Frederick would find all his resources of men exhausted. Frederick, who was never very scrupulous with regard to the means which he employed for the promotion of his ends, immediately compelled his prisoners of war, of whatever nationality, to enlist in his service.Two Silesian barons called upon him, and presented a protest from the authorities they represented against his meditated invasion, the design of which was now manifest to all.
