On the 30th, Lord Nelson arrived at Palermo; and, having learned that the Bey of Tunis had stopped several vessels with his lordship's passports, he immediately wrote a very spirited letter to Mr. Magra, the consul, and another to the bey, which he dispatched in the Earl of St. Vincent cutter on the 4th of June. In these letters, however, he again offers his services, as the mediator of a truce, or peace, with his Sicilian Majesty, as well as with the Portuguese; and observes, that the Marquis De Niza is ready to send a ship for this latter purpose. His lordship assures the Bey of Tunis, that he has granted no passports to any vessel which his highness, and every good man, will not highly approve of; and, that those who would, or dare, counsel his highness to prevent food from being given to those who are fighting in the cause of God against those vile infidels the French, are no better than Frenchmen. "I will," says his lordship to the consul, "have my passports respected, given only to serve the cause in which his highness ought to be as much interested as I am. This you will state clearly and forcibly to the bey--that, as I will do no wrong; so, I will suffer none: this is the firm determination of a British admiral." In a letter written to the Earl of St. Vincent on the following day, June 5, his lordship says, after noticing the conduct of the Bey of Tunis, "I hope to bring this gentleman to reason." He adds--"My time has been so taken up, that I have not been able to pay that attention to the Barbary States I could have wished, but I know these people must be talked to with honesty and firmness." His lordship had, indeed, just received, from Tripoli, a tolerable good proof of the efficacy of his mode of dealing with the Barbary States, in the success of Commodore Campbell, of which his lordship thus writes to the earl--"We are better friends with the Bashaw of Tripoli than ever. Commodore Campbell, whom I selected for that purpose, in the first place, because he was fit for the business; and, secondly, to mark that, although I could _censure_ when wrong, yet that I have no resentment for the past; having done, on that occasion, what I thought right. The commodore has, on this occasion, conducted himself with proper spirit and judgment; and he has, by it, made a very advantageous peace for Portugal." So completely did Commodore Campbell act up to the spirit of Lord Nelson's orders, that the bashaw actually delivered to him all the French who were at Tripoli, nearly forty in number. These, his lordship sent in the Susannah cartel, carrying French prisoners to Genoa, which sailed on the 6th of June; honourably stating, that they were not to be considered as prisoners of war, having been sent from Tripoli, in Barbary, for political reasons. On the 7th of June, in consequence of his lordship's recent information of being promoted to be Rear-Admiral of the Red, he quitted the Vanguard; and, on the 8th, hoisted it on board the Foudroyant.
