Generals Ambrosio and Camnaul were wounded. " General 7.sleipperg, with his corps, was in communication with General Bianchi, by Nepi. The Neapolitan army retreated by Fermo and Peseera. • Subsequent Letters from Lord Burghersh. dated Rome, 'lilac 7, i , tate, that General Neineerg arrived at Monte Cassiano on the 3d at night, and was ordered to meet Geneial 13 anchi en the 4th at Macerata..

The peasants in the neighbourhood took an active part in the pursuit of the Neapolitan fugitives. " Major Flette. after this success, marched upon Aquila, where he arrived on the 2d. The garrison, consisting of 300 men. retired into a castle on his approach. On the 4th they capitulated, giving up . ten pieces of artillery, with a considerable quantity of amm unition, and being allowed to return to Naples, under the condition of not serving against the Allies for the space of one month. The following is an extract from an Imperial Proclamation published at St. Petersburg, on the 25th of Art il, addressed to the French nation, and which reached us Tuesday by the Gettenburg mail APRIL 25.—w" You entered my territories, unprovoked, with fire and sword you plundered and destroyed wherever you came ; you en tered my capital, which you laid waste. I entered your territories, and took your eapital, but destroyed nothing. Again, unprovoked, you raise the sword, and destroy the peace of natio! s. I will now enter your territories once more, to conquer peace ; and wherever I meet with reAktance, I will utterly destroy you for your perfidy." The Sovereigns were expected to leave Vienna about the 15th inst. and tpke up their head-quarters in the vicinity of the nine. preparatory to the tremendous conflict which is ibcut to commence. It is evidently the object of the MAY OS, - Allies to move forward on one great preconcerted plan, sad hence it may be a week or two before any blow is struck. Louis XVIII. has published a Manifesto to the French nation, in which he states, that, with the exception of a Or tion of the army, the whole of his subjects are desirous of his return ; and that invitations to that effect daily reach him, not only from all points of the northern frontier, but from all quarters of his kingdom, even the most distant :-- " Frenchman," adds the Manifesto, the King, wherhas always been near you, will soon'tie with you. Hi, Majesty, the day on which he shall 'et foot on his territory and your's, will make known to you in detail his salutary intentions, and all Isis measures of order, justice, and yi,u will see that the period of his retreat has not beets lisle lust for your interests, and that tke Kiue has reigned by the c••res of his. foresight, even when he did not reign in the exercise of his authority." Besides this Manifesto, written by Count Lally Tolendall, a report of the state of France, by Chateaubriand, has also been published ; in which he asserts that all the moral force of France, and the torrent of public opinion, are for the King.—The Frenchmen now assembled at Ghent, under the Bourbon standard, are estimated at 5000: with the ac cession of daily arrivals, many of whom, French officers of rank, repair to British ports, and from thence proceed to join their Sovereign. Intelligence of an insurrection in La Vendee (headed by Charette, son of the renowned general. and OlerOn), was communicated on Monday in a dispatch, from the Duke of Bourbon to the duchess of Angouleme, dated from St. Gilles., The Duke had never quitted that part of France since the return of Bonaparte ; but has been actively employed there in preparing the insurrection which has just exploded. In this effort he has been zealously supported by our Govern ment ; some time since a secret expedition sailed from En gland with arms and military stores of every description, for the use of his adherents. M. Roche Jaquelin, and many French loyalists of distinction, went out at the same time. THE NATMNAL REGISTER: ......11‘.... Mr. Hunter, jun. the Messenger, arrived at the Foreign Office, in Downing-street, on Friday night, with dispatches from the Duke of Wellington, at Brussels. The commence ment of hostilities was daily expected to take place. Dispatches were received on Thursday at the office of Lord Castlereagh, from Vienna, containing the Emperor of Austria's ratification of the Treaty of the 25th March, en tered into by the Allied Powers against Buonaparte. Paris Papers to the 23d inst. and a Mail from Holland ar rived on Thursday. The intelligence by the latter is im portant. The principal body of the French Army, which was at Valenciennes has suddenly marched in three Columns, of sixteen thousand men each, towards the Meese, taking the road of Givet. From this moment, it is probable the enemy have resolved to strike the first blow, by an attempt to turn the left of the Allied Army; but as the Duke of Welling ton must have immediately observed the change of position thus effected, we may rest satisfied that the necessary mea sures were promptly taken to frustrate the enemy's design. The King of the Netherlands has appointed the Duke of Wel lington Commander in Chief of the Army of the Netherlands. The Emperor of Russia has addressed a letter to the Polish Senate, announcing that the Congress has determined, that Poland shall maintain the rights of an independent kingdom, and that his Majesty, in assuming the title of King of Poland will seek only the happiness of the country. The kingdom is to be united to Russia, but to be governed by its own Con stitution. It is once more asserted, that the King of Saxony has given his formal assent to the proposed incorporation of part of his territory with the Prussian dominions.
