The unanswerable reasoning in this letter could not fail to produce perfect conviction; and General Naselli, at his lordship's request, consented to lay an embargo on all the vessels at Leghorn, till he should receive orders for their disposal from his Sicilian majesty. Among these ships, were a great number of French privateers; some of them, his lordship observed, in a letter to Sir William Hamilton, of such force as to do the very greatest mischief to our commerce, if permitted to sail. There were also about seventy sail of vessels, calling themselves belonging to the Ligurian Republic, before called Genoa, ready to sail, loaded with corn, for Genoa and France; the arrival of which, must expedite the entrance into Italy of more French troops. "General Naselli," says Lord Nelson, "sees, I believe, the permitting these vessels to depart, in the same light as myself; but, there is this difference between us--the general, prudently, and certainly safely, waits the orders of his court, taking no responsibility on himself; I act from the circumstance of the moment, as I feel it may be most advantageous for the honour of the cause which I serve, taking all responsibility on myself."
