On the 15th we descended by a narrow pass, about a league in extent, which had the appearance of being scarped; the road was extremely rugged, and, winding suddenly, we found ourselves in the valley of the Ebro, which extended some distance to our right. The beauty of the scenery was far beyond description, and the rocks rose perpendicularly on every side, without any visible opening to convey an idea of any outlet. This enchanting valley is studded with picturesque hamlets, orchards of cherry trees, and fruitful gardens, producing every description of vegetation. We crossed the river by the Puente Arenas, where we saw a number of sturdy, thick-legged women, loaded with fresh butter, from the mountains of the Asturias. I had not tasted that commodity for more than two years, therefore it will be unnecessary to describe how readily I made a purchase, and carried the treasure in front of my saddle, until we had encamped; but, as ill luck would have it, there was not any biscuit served out on that day.

The next morning we ascended by a most romantic winding road for a league, and obtained a view of the tents of the fifth division, who had made a détour to outflank the enemy, and to secure the passage of these narrow defiles. While passing a village, I asked several of the inhabitants to sell me some bread; a shake of the head was the only answer returned. I at last caught a glimpse of a priest, and, as I was determined to have bread to eat with the fresh butter, I made towards him, saluted him by a most gracious bend, pulled out a pecéta, and requested he would procure me a loaf; he very good-naturedly acquiesced, and soon again made his appearance with a three-pounder, and also returned half my money: he seemed pleased, so was I, and, more courteous salutes having been exchanged between us, I rejoined the ranks. Travelling onwards, we perceived a large building on the side of a hill, with something white waving at each window, which, on a nearer view, we perceived to be a convent, and the nuns shaking their white handkerchiefs to greet our approach. On taking up our ground for the day, the baggage made its appearance, and ample justice was done to the bread and butter by myself and companions.

On the 18th, while we were advancing left in front, along a narrow road, shrouded by overhanging woods and high mountains, a hussar informed us that the enemy were at hand. On reaching a more open space, we observed a brigade of the French drawn up behind a rivulet, and their front covered by a few houses. Two battalions of the rifle corps, supported by the 52nd, instantly attacked them, and, after some smart firing, the enemy gave ground. During this skirmish our regiment turned off the road to the left, and formed line on a hill, as a rallying point, in case of need; when, to our astonishment, we observed the head of another column of the French issuing, by a road parallel to us, out of an opening between two perpendicular rocks, and in rear of our second brigade, already engaged. The other regiments composing our brigade scrambled over the rocks, to endeavour to attack their left, which the enemy perceiving, turned off the road, and made for a hill: the 52nd brought up its left shoulder, and actually formed line facing to the rear, at a run, and encountered the enemy on the crest of the hill, who, the moment they met that regiment, turned round, and, throwing off their packs, fled to the mountains, keeping up a running fight. The second brigade was now engaged front and rear.

During this desultory fusillade, the baggage belonging to the French division debouched from the already described outlet. The whole of the enemy's escort huddled together, and made a most desperate resistance amidst the rocks, while their affrighted animals ran loose, and were seen on the highest pinnacles of precipices. Nearly the whole fell into our hands, besides three hundred wounded and prisoners. The position of the division became singular after the fight, with its centre at the village St. Millan, and keeping a look-out to the front and rear. The enemy had also attacked the left of our army, near Osma, in hopes that, by causing such a delay, it would enable these two brigades, marching from Frias, to form a junction with their main body.

On the 19th we moved forward, and, at about ten o'clock in the morning, part of the fourth division became engaged with the light troops of the enemy. Our division then made a short détour, and turned the left of the French, who precipitately retired towards Vittoria. The next day we halted, and the army took up a line on the river Bayas, after long and arduous marching. The Marquis of Wellington approached the river Zadorra, which covered the enemy's position, for the purpose of examining the ground they occupied, and pointing out to different generals the various debouches, and their necessary line of attack, in the event of the French continuing to occupy the same ground on the following day.

On the 21st, we stood to our arms, and moved forward in darkness, some time before daybreak. A heavy shower of rain fell; but, as morning dawned, the clouds dispersed, and the sun arose with fiery splendour. A towering and steep ridge of mountains rose abruptly from the valley on our right, which the Spaniards climbed early in the morning, at first unopposed; the ascent was so steep, that, while moving up it, they looked as if they were lying on their faces, or crawling. They were supported, and soon followed across the river Zadorra, and through the town of Puebla de Arlanzon, by part of the second division, for the purpose of attacking the left of the enemy, who were posted on the heights above Puebla de Arlanzon and Sabijana de Alava, where the contest, at the former place, began at nine o'clock, amongst deep ravines, rocks and precipices. The second division becoming heavily engaged with the enemy, under all these disadvantages it could only maintain the ground already won, and the firing seemed to die away in that quarter. Our right centre, composed of the light and fourth divisions, continued to advance, as also the great bulk of our cavalry.

At about ten o'clock, on ascending a rising ground, we observed the French army drawn out in order of battle, in two lines, their right centre resting on a round hill, their left centre occupying a gentle ascent, and their left hid from view on the heights of Puebla; the river Zadorra ran at the foot of this formidable position, and then took a sudden turn, embracing and running parallel to their right flank, towards Vittoria.

El Rey Joseph, surrounded by a numerous staff, was stationary on the hill, overlooking his own right and centre. The French army was unmasked, without a bush to prevent the sweeping of their artillery, the charging of their cavalry, or the fire of their musketry from acting with full effect on those who should attempt to pass the bridges in their front, and which it was absolutely necessary to carry before we could begin the action in the centre. When within a short distance of the river, five of the French light horse advanced on the main road to look out, and were overtaken by an equal number of our dragoons, when they wheeled about and attempted to make off, without effect; they were assailed on the near side, when three instantly fell from their saddles, covered with sabre wounds, and their affrighted horses galloped at random.

The light division left the road when within one mile of the river, and drew up in contiguous close columns behind some shelving rocks near Olabarre, with the hussar brigade dismounted on the left; the fourth division made a corresponding movement, by branching off to the right, and took post opposite their intended point of attack; the greater part of our heavy cavalry and dragoons remained in reserve, to succour the central divisions, in case the enemy should advance before the third and seventh divisions should have taken up their ground on the enemy's right flank. The first and fifth divisions, with two brigades of Portuguese, a Spanish division, and two brigades of dragoons, were making a détour from Murguia, to place themselves on the line of the enemy's retreat, towards St. Sebastian; the sixth division remained some leagues in the rear of our army to guard the stores at Medina. Gen. Clausel's division was manœuvring on our right, but not sufficiently near on this day to give much cause of apprehension.

All the movements of our army required the nicest calculations, both for the attack and defence; for at this time the four great columns advancing were separated by difficult rocks and a rugged country, interspersed with deep gulleys, narrow roads, and scattered hamlets. The enemy were again under the painful necessity, for the third time in one month, of manœuvring on two sides of a square; and the first cannon fired by General Graham, at Abechucho and Gamarra Major,[48] must have been to Joseph and Marshal Jourdan, (his Major-General,) like a shock of electricity: all in an instant was riot and confusion in Vittoria; the baggage stuck fast, blocking up all the roads, and even the fields.
