Not even the judicious plan which his lordship was now busily engaged in arranging for the recovery of Naples, with all the other objects of his incessant care, could divert his attention from that grand object, the entire destruction of the French armament sent to Egypt. He had just received information of the, surrender of Corfu; and, about this time, a very elegant and flattering letter had been written to his lordship by the King of Sardinia, full of gratitude for the protection of the British flag in conveying him from Leghorn. In writing to the Earl of St. Vincent, after mentioning these subjects, with the return of Captain Troubridge's squadron from Egypt, he observes that it is his intention to send a small squadron, under that commander, into the Bay of Naples, "I wish, first," says his lordship, "to take the Island of Procida, which will secure a tolerable anchorage, and effectually blockade Naples. It must, also, have the effect of preventing the French from detaching any troops from Naples to to the provinces, who are all loyal. The court tells me, that twelve thousand Russians, and fifteen thousand Turks, are ready to cross the Adriatic, to land in the kingdom of Naples. If so, our squadron will create a powerful diversion." Having stated the reasons which have been seen for Captain Troubridge's failure at Alexandria, he adverts to Sir Sidney, who has now the blockade of that place. "I send you," says his lordship, "copies of my letters to him; for the victory of the Nile would, in my opinion, be useless, if any ship, or Frenchman, is suffered to return to Europe. I hope you will approve of my conduct; for, as a captain to an admiral, either Sir Sidney Smith, or myself, must give way. Bonaparte is at Cairo, not more than sixteen thousand strong. He must and will fall, sooner or later, if Sir Sidney Smith does not allow him to retreat by sea. As to myself, I am, at times, ill at my ease: but, it is my duty to submit; and, you may be sure, I shall not quit my post, without absolute necessity. If the emperor moves, I hope yet to return the royal family to Naples. At present, I cannot move; would the court but let me, I should be better: for, here, I am writing from morn to eve; therefore, you must excuse this jumble of a letter." Neither of these letters, however, mention the very important circumstance of Captain Troubridge's having intercepted Bonaparte's dispatches, on his way to Constantinople; which is contained in the following communication to his Excellency the Honourable William Windham, for the purpose of having that satisfactory intelligence transmitted to England. This letter, as well as other dispatches of the 21st, to Mr. Windham, was written on board the Culloden; into which ship Lord Nelson had shifted his flag, having that day sent Captain Hardy to Tripoli with the Vanguard. "Culloden, Palermo, 22d March 1799. "MY DEAR SIR,
