The regiment was formed in front of Calcabellos covering the rear of the infantry, and on the first appearance of the enemy they had been ordered to withdraw behind the town. Three parts of them had already passed the bridge, and the remainder were upon it, or in the act of filing through the street with the careless confidence which might be expected from their knowledge that the British cavalry still stood between them and the enemy; but in an instant our own cavalry, without the slightest notice, galloped through and over them, and the same instant saw a French sabre flourishing over the head of every man who remained beyond the bridge--many were cut down in the streets, and a great portion of the rear company were taken prisoners. The remainder of the regiment, seeing the unexpected attack, quickly drew off among the vineyards to the right and left of the road, where they coolly awaited the approaching assault. The dismounted voltigeurs first swarmed over the river, assailing the riflemen on all sides, but they were met by a galling fire, which effectually stopped them. General Colbert next advanced to dislodge them, and passing the river at the head of his dragoons, he charged furiously up the road; but, when within a few yards of our men, he was received with such a deadly fire, that scarcely a Frenchman remained in the saddle, and the general himself was among the slain. The voltigeurs persevered in their unsuccessful endeavours to force the post, and a furious fight continued to be waged, until darkness put an end to it, both sides having suffered severely. Although the principal combat had ceased with the day-light, the riflemen found that the troubles and the fatigues of twenty-four hours were yet in their infancy, for they had to remain in the position until ten at night, to give the rest of the army time to fall back, during which they had to sustain several fierce assaults, which the enemy made, with the view of ascertaining whether our army were on the move; but in every attempt they were gallantly repulsed, and remained in ignorance on the subject until day-light next morning. Our people had, in the meantime, been on the move the greater part of the night, and those only who have done a mile or two of vineyard walking in the dark, can form an adequate notion of their twenty-four hours work.
