Had they placed their armies at our disposal, and allowed the introduction of the active and intelligent British officers into command, their regular army might have become as celebrated in after-ages for the defence of the Peninsula, as the Portuguese or their own Guerillas; while at present, with the exception of their irregular warfare and defence of cities, their military character, during a period so brilliant for their allies, both Portuguese and British, appears absolutely contemptible. The army which we joined at Oropesa, in addition to its other drawbacks, was headed by a general as decrepit in mind as body. To abilities not superior to the most common intellect he united the greatest fault in a commander of an army, that of indecision, while every act bespoke his suspicion and jealousy of his allies and their commander. Attached to this army was an example, in the person of Lord Macduff, of one of those gallant spirits, who occasionally shaking off the indolence of wealth, volunteer to aid some soul-stirring cause. His Lordship had the rank of a Spanish Colonel. On the 21st, the two Commanders-in-Chief dined together, and in return for the military spectacle Cuesta had given to Sir Arthur at Casa de Puertos, when he visited him from Placentia, the British troops, with the exception of Gen. M'Kenzie's division on the advance, were drawn out in the evening for his inspection. The mounting on horseback to proceed to the review, showed how ill-fitted was Cuesta for the activity of war. He was lifted on his horse by two grenadiers, while one of his aide-de-camps was ready on the other side to conduct his right leg over the horse's croup, and place it in the stirrup! Remarks were whispered at this moment, that if his mental energy and activity did not compensate for his bodily infirmity, Sir Arthur would find him but an incapable coadjutor. The Spanish General passed along the line from left to right, just as the night fell, and we saw him put comfortably into an antiquated square-cornered coach, drawn by nine mules, to proceed to his quarters.
