Charles-Guillaume-Ferdinand duke of BRUNSWICK (1735-1806) L.A.S., Bronsvic January 14, 1799, to marshal de Castries; 1 page in-4. About a memoir on Louis XVIII: "What a difference if the powers according to the opinion of M. Hermann, by recognizing Louis XVIII, would have shown him to France, as the rallying point of all parties. This measure which seemed quite simple [...] was always fought by political sophisms, which are the source of our present and future misfortunes". He wishes that on his return from Berlin "we see more clearly in the affairs of Italy, it is difficult not to believe in secret relations between Vienna and Paris"...
