Diary of John Adams, volume 4
From François de Barbé-Marbois Sir 29th. of September 1779 I have only time to inform you, how much interest I have taken in the Choice which your Countrymen have made of you, to go and negotiate the Peace in Europe. I have been really touched, by that Unanimity and Zeal, with which all Minds have united, in the Opinion which they have conceived of you; and in the Persuasion, that a Minister, without Prejudices and without any other Passion than that for the Happiness of his Country, and the conservation of the Alliance, was the Man the most proper to conduct the important Work of Peace.
I desire very much, Sir, that you would carry with you again to Europe, the young Gentleman your Son, notwithstanding the Aversion he has to Navigation. He will learn of you the means of being, one day, usefull to his Country; and your Precepts and your Sentiments will teach him to cherrish my Nation, who perceive more and more from day to day, how much her Union with You is natural and reciprocally advantageous. I am, with respect, Sir your most humble and most obedient Servant
