It isn't often mentioned but, after the end of war, Sir Sidney Smith dedicated much of his time and efforts to ending white slavery. As a result, there were several British navy missions undertaken to finally end the practice.
Much of Smith's efforts in this area was in the form of personal letters to the Royalty that he knew.
From "The Life and Correspondence of Admiral Sir William Sidney Smith, Volume 2" Sir Sidney's letter to a Turkish bey; it seems to confirm Smith's unique character:
"Vice-Admiral Sir W. Sidney Smith, Knight Grand Cross of the Tower and Sword, Knight Commander of the Bath, Companion of the Imperial Ottoman Order of the Crescent, President of the Knights Liberators of the Slaves in Africa, to his Highness the High and Puissant Prince Bey, and Governor of [purposely obliterated]. Salut! Salut! Salut! "High And Mighty Sir," The fame of your exalted virtues has reached us. The many instances of your justice, benevolence, and hospitality are known to us. We therefore address you in confidence, and offer you the opportunity of becoming a member of our illustrious society of knights liberators of slaves in Africa. This illustrious and highly noble association being composed of the persons of the most exalted rank and highest endowments in the world at large, you will no doubt be as desirous to enroll yourself a member thereof, as the members are to see you belonging to their body. What certain detached members of our community have done in South Africa, at Algiers, in Tripoli, and in Egypt, towards the abolition of slavery among men, is well-known to you; what remains to be done is daily before your eyes; and we call upon you, as a good Mussulman whom we respect, and as the descendant of the illustrious and high-minded (name purposely obliterated), our respected and lamented friend, whose virtues and power you inherit, to aid us in this great work. You have been graciously pleased to liberate the white slaves, and we doubt not you will discourage the practice of buying and selling black men, in deference to the precepts of the Koran, and remembering the saying of Sidna Mohammed. "In giving liberty to slaves you will follow his sublime example when he, at an advanced age, liberated as many as he was years old, hoping thereby to do a thing pleasing to God. In giving us the satisfaction of knowing that you do so, by a friendly letter, you will extend to us the supreme pleasure you will yourself feel, and merit the title we wish to extend to you, of a knight liberator. This letter having no other object, we wait your friendly answer, and the expression of your wish, that we should do something agreeable to you; which we are ready and willing to do at all times; and we pray God to exalt you in dignity, and to have you in his holy and especial keeping."Your true friend, W. Sidney Smith."
