It will be known to the reader, perhaps, that on the 25th, Soult (who had now been appointed to the command of the French army) made an attack upon our posts at Roncesvalles and Maya, and had driven the divisions stationed there from their posts. He moved on towards Pamplona, in hopes either of beating back our army to Vittoria, (as he vainly talked,) or of being able to supply Pamplona with provisions, which it greatly needed. In consequence of this movement of the enemy, we also were compelled to fall back, although the troops in front of us made no demonstration of advancing.

Accordingly, on the 26th, we began our retrograde movement, being myself at that time in as pitiable a plight as can well be conceived. My horse was so utterly lame, that he could scarcely hop on three legs, while I was totally unable to walk a step. My kind friend Captain Perceval, with whom I had long messed, helped me out of my trouble, by dividing the load of one of his baggage-ponies among the other animals, and lending it me to ride upon. We retired from the height, and crossed the river Bidassoa, near Lizacca, through which we passed, and kept along the mountains on the left bank of that river till we reached a height opposite Sumbilla, where we pitched our tents, and remained for the night. We did not move all next day; but just as night set in, we were ordered under arms, and continued our retreat. This was a still more distressing night-march than any I had previously witnessed.

We were now, it may be noticed, in the midst of the mountains of the Pyrenees, where precipices abound; consequently the precaution to avoid falling over them would be doubled. One little streamlet, I well remember, delayed the division probably two hours. It came down from the sides of the mountain which overhung the road, and crossed it at a very dark and ugly-looking place, making a considerable noise as it fell from rock to rock. This of course made every one extremely cautious; and in consequence a poor good-natured corporal, who was killed soon after, got himself into the middle of the streamlet, and took hold of every person's hand as he passed, conducting him safely to the other side. Poor fellow, he was extremely anxious to help me and my miserable little pony safely over. This and a few other places, something similar, prevented us reaching our destination till an hour after daylight next morning, although the whole distance was not more than ten miles.

We arrived at Zubietta in the morning. This place is about a league to the right of St Estevan, more into the mountains. Here we remained that day, and the next day moved higher up the mountain, behind the town, where we encamped, and remained till evening, when we again commenced our retreat. We had not quite so bad a march of it this night, the road being much more even, although, just at the outset, our adjutant, in riding along, had his cap pulled off by the bough of a tree, and in endeavouring to save it from falling, he pulled his horse right over a small precipice, which the two rolled down together. Luckily it was not a deep ravine into which he fell, or he would not have escaped so well: neither man nor horse were much hurt. We reached the village of Saldias in the morning, where we remained for the day. Last night my servant told me he had been obliged to leave my little horse behind, as he could not get him to hop any farther. I felt grieved at this, for he had brought me all the way from Lisbon, and shared both my good and bad fortune; however, it was no use to fret, for that would not improve my situation, which indeed was not an enviable one, my leg all this time being extremely painful.

On the 30th, we made an excessively long march, (by day,) and at night reached Lecumberg, where we encamped. During the latter part of this day's march, we had heard an incessant cannonade and firing of musketry in the direction of Pamplona, from which we were apprehensive that Soult had penetrated too far; but as it did not appear to recede, we believed our people had been able to hold him in check at least. We were now on the great road from Bayonne to Pamplona, in order to keep up the communication between our right, where the fighting was now going on, and Sir Thomas Graham, who was besieging St Sebastian. We were here also to intercept any of the enemy's columns that might either advance or retreat by this road. Towards evening of the 31st, an aide-de-camp arrived from Lord Wellington, more dead than alive from the excessive fatigue which he had undergone for the last three or four days, with news of the total defeat of Soult in the several actions near Pamplona, termed the Battle of the Pyrenees, and ordering us to retrace our steps, and again advance. We set off in the evening, and reached Larissa, where we halted for the night. It was whispered that it was expected we should have gone much farther this night, but I am not certain whether it is true; but certainly we might have proceeded to Saldias, if absolutely necessary.

On the morning of the 1st of August, we again started pretty early. It was again reported this morning that another dispatch had been received during the night, directing us to proceed with all haste, as the enemy were retreating by St Estevan, and that we were to attack them wherever we met them. We now of course stepped out very freely, and presently gained Zubietta. Here I had ridden forward to get a shoe fastened on, my horse having cast one in coming over the mountains; during which time the quartermaster had been called for some purpose or other, as I was not there.

My General was not well satisfied: he saw me in this village, and asked me why I had not been present when I was wanted. I told him the cause, but he still did not appear satisfied, and, by way of punishment, directed me to remain in the village till the baggage came up, and show them the way the division had gone. I may here observe, that it was a little unreasonable in my General to find any fault with me on this occasion; for, had I not got the shoe put on my horse, I could not have been of any use at all as a quartermaster. My punishment indeed was slight, and I rather think he was glad to find any excuse to delay me for the purpose for which I was left. I am confident the officers of the infantry suffered more anxiety and even loss on account of the great want of farriers or horse-shoers in their regiments, than from almost any other cause. Without the officer was pretty high in rank, he had not only to pay most exorbitantly for any thing of this kind which he got done, but to beg and pray, and to look upon it as a favour conferred on him. Most of the good shoers were taken by the staff or general officers, consequently only the inferior ones were left for the regimental officers, and in several cases none at all. The consequence of all this was, the loss of several valuable animals, both horses and mules; besides, in some cases, the officers being rendered incapable of performing their duty as they otherwise would have done. To this I attribute a considerable loss in animals during this service. It might easily be remedied by each infantry regiment having a proper establishment of farriers, (say two,) with tools, &c. in proportion, and the means of carrying them; and then every officer, whose duty requires him to be mounted, might be served. I myself bought tools to the amount of L.4, and never had but one horse shod with them. I could not get a man to do it. As soon as I saw the baggage on the right way, I pushed forward, and joined the division again. We were literally at this time climbing up a mountain, where I could not ride, but was obliged to crawl up, and pull my horse after me. My leg by this time had much improved. We followed the road by which we had retreated a few days before, and at length came to the rivulet that had so alarmed us all on our night-march. It was really surprising that we should have been stopped so long by such a trifle; but in such a situation, and at such a time, things of that kind are magnified a thousandfold by the imagination. We passed our old camp ground opposite to Sumbilla, and here we came in view of the enemy's columns retreating along the road on the opposite bank of the Bidassoa. This gave our men new life; but here the 52d and other regiments of the 2d brigade were obliged to halt: they could proceed no farther.

We had marched by this time to-day two and a half of the stages we made in retreating; but the 2d brigade had been in the rear of the column all day, and had consequently suffered much from stoppages, &c. My battalion, our 1st battalion, and the 43d regiment, continued to move on, and as they approached, the enemy seemed to acquire fresh vigour. At length we reached the point of attack,—the bridge of Yanzi,—and here the 1st battalion turning down towards the river, at once left the wood and ground above the bridge to be occupied by us. The enemy sent a pretty strong corps of light troops across, which got engaged with our people; but we soon drove down through the wood again towards the bridge. At length, we got two companies posted just over the bridge, in front of which all the rear of the French column had to pass. Poor creatures! they became so alarmed, that they instantly began to cut away, and cast off, all the loads of baggage, and both cavalry and infantry, &c. to make the best of their way. But the mountain on their right was inaccessible; consequently they had all, as it were, to run the gauntlet. Great was the execution done amongst the enemy at this bridge, and many were the schemes they tried to avoid passing. At length they got a battalion up behind a stone wall above the road, on the opposite side, from whose fire we received some damage; consequently those poor people who had afterwards to pass were not so much exposed. Just about the close of the business, my kind friend, Captain Perceval, received a shot through his right wrist. His left hand had been closed for a length of time before, in consequence of a wound through that wrist, which had contracted his fingers, besides being lame from a wound in the hip. Now he was rendered completely useless. Towards dusk I went with him a little to the rear, and got his tent pitched, and made as comfortable as circumstances would admit. I pitied the French on this occasion, they seemed so much alarmed. The whole of their baggage fell into the hands of our 4th division, who were closely following them up on their side of the Bidassoa.

In this affair, the French were reduced to a dreadful dilemma; great numbers of their wounded had been brought off from the battles of the 28th, 29th, and 30th, near Pamplona, which were carried on biers or stretches by men of this division. When they saw us in front of them, where they had to pass, as it were, immediately under the muzzles of our pieces, they were compelled to adopt the cruel alternative of either throwing their wounded men down to perish, or run the risk of being shot or taken themselves. I believe the former, shocking as it seems, was generally adopted; and I have reason to believe that the greater part of them were thrown into the river; for, from the point where we first came in view of them to near where this affair took place, the Bidassoa was literally filled with the dead bodies of Frenchmen, and they could have come into it in no other way. We lost only a very few men on this occasion, not more than six or eight, while that of the enemy must have been extremely severe. Here the effects of rifle-shooting were plainly visible.

In remarking on this affair, I beg to draw the reader's attention to the following circumstances; viz. probably never troops made such a march over such a country before. We travelled at least thirty-two miles over mountains such as I before described, where you were sometimes nearly obliged to scramble upon your hands and knees. The day was exceedingly hot, and occasionally there was a great want of water. I am told that one of the regiments in our 2d brigade, which, it may be remembered, were obliged to halt, as they could go no farther, had no less than 200 men fell out, unable to keep up, and that some of them actually died of fatigue. I heard of one poor fellow, who, when he came to water and had drunk, lost his senses, fell to the ground, and shortly after expired. I have reason to be proud of my battalion on this occasion, which, when the roll was called, just before the action commenced, had only nine men fallen out; but they had been in the front all day, a great advantage in marching, particularly over a mountainous country.
