CASTLEREAGH.  We have been informed, and we are not without hope that our information will prove correct, that Minist.rs have come to the laudable determination that the Island of Walcheren shall be immediately evacuated.  Measures are, however, to be taken, to render Antwerp useless to the enemy as- a naval arsenal. To effect this object orders have been sent to the Dockyard, at Portsmouth, to prepare eight line-of-battle ships to be sent there, and then to be sunk in the different passages of the Scheldt. The Maida, l'Hercule, two more English ships, and four Danes, are pitched upon for this service.  A letter (of which a copy has been received in town) written at Bejar on the 10th ult. by an Officer in the Portuguese Legion to a friend at Lisbon, relates some particulars of the laborious and critical march of Sir ROBERT WILSON and his gallant little corps, from his station in the neighbourhood of Escalona towards Banos, by the circuitous route rendered necessary through the unfortunate abandon. ment of Talavera. The more important particulars of this route have already been transmitted by Lord WELLINGTON ; and this corps was too insulated to know much of the general state of the campaign : yet it is said, in this letter, that the Marquis of ROMANA was prevented from occupying Salamanca, on account of the bridges of Toro and Zamora being cut. One fact we learn from this letter, which is a novelty. The French' had forced a number of Spaniards to enlist in their service ; 95 of them, however. made their escape from the Escurial, and joined the Legion ; and could Sir ROBERT WILSON have remained a day longer at Naval Corneiro, there is no doubt that the whole body would have joined. On one occasion, all the baggage, including the papers and military chest, had a very narrow escape from being seized by the enemy, and were saved only by being conducted over the almost impracticable pass of Valverde. It appears that, in the beginning of last month, while the issue of the campaign was still doubtful, dispatches were intercepted at El Fieublo, containing, besides instructions relative to the war, an account of a peace having been concluded between France and Austria, according to which the Emperor FRANCIS had resigned all his dominions except Hungary ;-1 and it was added, that in six weeks BONAPARTE was to be at Madrid. This intelligence appears to have occasioned considerable uneasiness : but it is believed that the dispatch was an artifice to precipitate the retreat of the combined army, and to induce the English Commander in Chief to retire upon the naval frontier, under the impression that all further resistance to the arms of France would be in vain.  Among the Officers of the Legion, the neglect to defend the pass of Banos, in the first instance, appears to have been considered as a most calamitous event ; and it was understood that two days after the battle of Talavera, Lard WELLINGTON, as well as General CUESTA, was inclined to detach the Legion to guard that important post; but a different decision was afterwards adopted. The soldiers of the Legion did the greatest credit to their officers, &ring this exhausting and trying march, and they appear to have been well received by the inhabitants in the course of it.  On the 10th, the Legion arrived at Cueta de adios, where they found the enemy had murdered 54 men, besides plundering every house in the town, and committing the most horrible excesses towards the women.  Yesterday, at twelve o'clock, his MAJESTY arrived from Windsor, at the Queen's Palace, and wai re. ceived by the Dukes of , YORK, KENT, and
