Klemens von Metternich on Robert Stewart, Viscount Castlereagh

“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.”

“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.”
