“Captain Kennedy, you will carry my orders at once, to our cavalry, to charge the Portuguese horse on the right wing.”

Desmond saluted, and was about to ride off, when he paused a moment and asked: 

“May I charge with Brigadier Crofton’s dragoons, sir?”

The marshal nodded, and Desmond galloped off.  Crofton was in command of the first line of cavalry.  His own regiment, which was composed partly of Irishmen and partly of Spaniards, was in the centre of the line.

After delivering his orders to the general commanding the cavalry, Desmond rode on to Crofton.

“The cavalry are going to charge, sir,” he said, “and I have permission to ride with you.”

Crofton waited until the order from the general arrived, and then, drawing his sword, shouted, “The first brigade will charge,” and, riding forward, led the way against the Portuguese horse, whose cannon had already opened fire.  The Portuguese fell into disorder as soon as they saw the long line of horsemen charging down on them like a torrent, and when it neared them broke and fled.  They were soon overtaken, great numbers were cut down, and the remainder galloped off, a panic-stricken mob, and did not draw rein until they reached Campo Mayor.

The Spaniards at once turned the five cannon the fugitives had left behind them upon the allied infantry, and then, after a few rounds had been fired, the cavalry charged the British infantry.  But they had now foes of a different metal to reckon with, and although, three times, the horsemen reformed their ranks and hurled themselves against the infantry, they were each time repulsed with heavy loss.

Then, swerving round, they fell on the Portuguese infantry in the second line, whom they dispersed as easily as they had defeated the cavalry.

The Earl of Galway now brought up the brigade of Brigadier General Pierce, which consisted of the two British regiments of Barrimore and Stanwix, and a Spanish regiment which had been recently raised and named after himself.  These charged the enemy with great bravery, drove back their infantry for some distance, recovered the five guns the cavalry had lost, and, still pressing forward, fought their way deep into the centre of the Spanish ranks.

Had they been supported by the Portuguese infantry, on their flank, the battle might still have been won.  But the latter, in spite of the persuasions and orders of their officers, refused to advance, and, turning their backs, made off in confusion, although not yet attacked by the enemy.  Orders were then sent to the Portuguese horse on the left to charge to the assistance of Pierce’s brigade.  But instead of doing this, they also galloped off the field, and after defending themselves with desperate valour for some time, the little brigade, being unsupported, and being surrounded by the whole strength of the Spaniards, was forced to surrender.
