Klemens von Metternich on Robert Stewart, Viscount Castlereagh

“It is a great misfortune. The man is irreplaceable, especially for me... Castlereagh was the only person in his country who had experience in foreign affairs.”

“I cannot praise Castlereagh enough. His attitude is excellent and his work as direct as it is correct. I cannot find a single point of difference with him and assure you that his mood is peaceful, peaceful in our sense.”
