The only news of the slightest importance from Oporto, is
the retirement of a notoriously inefficient man, the Marquis DE VILLA FLOR, from the command of Don PEDRO'S army, and the assump- tion of the supreme command by the Emperor himself. Sir J. M. DOYLE will act as PEDRO'S Aide-de-Camp. It is rumoured that the French General EXCELMANS was about to take the command under the King; this would be a great acquisition. There has been a lamentable want of generalship hitherto, else the besiegers would have been in a very different position from that which they occupy. MIGUEL and his sisters, who travel with him, were on the 1st instant at Braga. The Liverpool steamer, for which some unfounded fears were entertained, has arrived safe at Oporto.
