On the 12th of November, Admiral Nelson, having a few days before arrived safely at Naples, went to the camp at St. Germaine's, in consequence of a request from his Sicilian Majesty, to meet General Mack and General Acton, at a grand review of the whole Neapolitan army; and Sir William and Lady Hamilton, with all the English nobility and gentry then at Naples, accompanied our hero, where they joined the king, queen, and royal family. The account of this meeting, and it's results, including an intended attack of Leghorn, are sufficiently explained in the following very interesting letter to Earl Spencer: which is farther remarkable for being the first epistle that our hero appears to have ever signed with the omission of his Christian name, in consequence of being advanced to the peerage; of which honour he had, even yet, it should seem, by what will be seen hereafter, no official information from the noble earl to whom he was writing, though he must certainly have received some regular previous information on the subject. "Camp, St. Germaine's, 13th Nov. 1798. "MY LORD, "A desire from his majesty called me here yesterday, to concert with General Mack and General Acton the commencement of the war. Thirty thousand of--_Mack says--"La plus belle d'armie d'Europe_," was drawn out, for me to see; and, as far as my judgment goes in these matters, I agree, that a finer army cannot be. In the evening, we had a council; and it was settled, that four thousand infantry, and six hundred cavalry, should take possession of Leghorn. The infantry--(having stopped Captain Troubridge's squadron for Corfu)--I shall embark in the Vanguard, Culloden, Minotaur, two Portuguese ships, (if I can get them ready, not that I see they have any wants) and the Alliance storeship. A Neapolitan ship brings the cavalry, in a convoy, after us. The king's order for the destination was to be given to me; and, when at sea, I was to give it to the general commanding the troops: who was to be totally ignorant, that Leghorn was the object, and not Malta; which, as a secret, was communicated to him. His majesty approved of this plan, and Mack was to march--I repeat it with pleasure--"with thirty thousand of the finest troops in Europe," on Saturday, the 17th, to Rome; and keep advancing, trusting to the support of the emperor. Every hour, the French are increasing their Italian army, and two new generals are arrived at Rome. Thus I went to bed last night; and, at six this morning, came to take leave of their majesties. I found them in great distress. The courier who left London on the 4th, has not brought any assurance of support from the emperor. M. Turget is evasive; and wishes, he says, the French to be the aggressors. It is aggression, if this court knows--all the world knows--that the French are collecting an army
