Siege of Cadiz: "I count on your zeal and the most active cooperation on your part to let nothing enter or leave Cadiz, and to support any landing that may be deemed necessary. Our Navy must prove that it is not inferior to that of the English, and that we can do everything they have done. Tell everyone under your command that I count on them as I do on the army". He must comply "with everything Bordessoule tells you on my behalf. [...] If your fleet contributes to the deliverance of S.M.C., believe in the happiness I will feel in showing you my satisfaction"...
