Not a moment's time was lost by Wellington after he received the news; but, unfortunately, six precious hours had already been wasted, owing to the despatches not having reached him at Canizal. With the three brigades of cavalry he set off at once towards Alaejos, while an officer was despatched to Canizal, to order the fifth division to march with all speed to Torrecilla de la Orden, six miles in the rear of Cotton's position at Castrejon. Four hours' riding brought them to Alaejos, where a halt for two or three hours was ordered, to rest the weary horses and men. Soon after daybreak, however, all thought of sleep was banished by the roar of artillery, which told that Marmont was pressing hard upon Cotton's troops. "To horse!" was the cry, and Lords Wellington and Beresford, with their staff, rode off at full speed towards the scene of action, with the cavalry following hard upon their heels. An hour's ride brought them to the ground. Not much could be seen, for the country was undulating and bare, like the Brighton Downs, and each depression was full of the white morning mist, which wreathed and tossed fantastically from the effects of the discharges of firearms, the movements of masses of men, and the charges of cavalry hidden within it. Upon a crest near at hand were a couple of British guns, with a small escort of horse. Suddenly, from the mist below, a party of some fifty French horsemen dashed out and made for the guns. The supporting squadron, surprised by the suddenness of the attack, broke and fled; the French followed hard upon them, and just as Lord Wellington, with his staff, gained the crest, pursuers and pursued came upon them, and in pell-mell confusion the whole were borne down to the bottom of the hill. For a few minutes it was a wild melee. Lords Wellington, Beresford, and their staff, with their swords drawn, were in the midst of the fight, and friends and foes were mingled together, when the leading squadrons of the cavalry from Alaejos came thundering down, and very few of the Frenchmen who had made that gallant charge escaped to tell the tale. The mists were now rapidly clearing up, and in a short time the whole French army could be seen advancing. They moved towards the British left, and Wellington ordered the troops at once to retire. The British fell back in three columns, and marched for the Guarena, through Torrecilla de la Orden. The French also marched straight for the river, and now one of the most singular sights ever presented in warfare was to be seen.
