The ambassador of Bonaparte being intercepted by my friend Troubridge, on his way to Constantinople, among other articles of his instructions, is a very important one; viz. an offer to enter on terms for his quitting Egypt, with his army. This offer is what I have long expected the glorious battle of the Nile would produce; but it was my determination, from that moment, never, if I could help it, to permit a single Frenchman to quit Egypt. Captain Sir William Sidney Smith, who has the present command of the squadron off Alexandria, I have reason to believe, thinks differently from me, and will grant passports for that part of the French army which God Almighty permits to remain. I have, therefore, thought it highly proper to send Captain Sir Sidney Smith the order of which I transmit a copy; for, I consider it nothing short of madness, to permit that band of thieves to return to Europe. _No!_ to Egypt they went, with their own consent: and there they shall remain, whilst Nelson commands this detached squadron; for never, never, will he consent to the return of one ship or Frenchman. "I beg your excellency will take the earliest opportunity of sending this important information, and a copy of my letter to Captain Sir Sidney Smith, to England; and ever believe me, with the greatest respect, your obliged and faithful servant, "Nelson." On the 25th of March, Lord Nelson says, in a letter to Captain Ball, dated at Palermo--"Now, my dear friend, Captain Nisbet is appointed to the Thalia, a very fine frigate, and I wish he may do credit to himself, and in her. Will you do me the favour of keeping her, and sending me La Minerve; for I want Cockburne, for service of _head_. As soon as Captain Barker's surveys, &c. are over, make one of the small craft bring him here. I have sent Vanguard to Tripoli, to scold the bashaw. Tunis behaves well. As Corfu has surrendered, I hope Malta will follow the example very soon. I am not well; but keep rubbing on, from day to day. God bless you; finish the business as soon as you can." Captain Dunn, in the Thalia, for Captain Nisbet, was the bearer of the above letter with other dispatches to Captain Ball; and Captain Maling took his passage in the Thalia, to supercede Captain Nisbet in La Bonne Citoyenne. Captain Dunn went to supercede Captain Barker in the Incendiary; on his appointment to the Barfleur; and he was required to join Lord Nelson by the very first opportunity, being wanted to go down the Mediterranean.
