Of St Sebastian, and the proceedings within it, I can say no more from personal observation, my post being now with the advance of the army; but I may as well add, that the castle still held out, and continued so to do, till the 8th of September. It was, however, as we afterwards discovered, wholly unprovided with shelter against the shells which were unintermittingly thrown into it; and hence, after suffering every possible misery during a whole week, the governor was at last obliged to surrender. About nine hundred men, the remains of a garrison of four thousand, became by this measure prisoners of war, and such British prisoners as had escaped the horrors of the siege were recaptured; but the place itself was utterly valueless, being in a state of the most complete dilapidation.

The whole of the 1st of September was spent under arms, and in a state of deep anxiety, by the troops which occupied the pass of Irun, inasmuch as various movements in the French lines appeared to indicate a renewal of hostilities. Many bullock-cars, laden with wounded Spaniards, passed in the meanwhile through our encampment; and the groans and shrieks of these poor fellows, as the jolting of their uneasy vehicles shook their wounds open afresh, by no means tended to elevate the spirits, or add to the courage of those who heard them. Not that there was any reluctance on our part to engage: I believe a reluctance to fight was never felt by Britons when the enemy were in sight; but a few of the real effects of war, contemplated in a moment of coolness and inaction, seldom has the effect of adding fuel to the valorous fire which is supposed at all moments to burn in the breast of a soldier; and, in truth, this was a piteous sight.

Of all the classes of men with whom I ever had intercourse, the Spanish surgeons are, I think, the most ignorant and the most prejudiced. Among the many amputations which during the war they were called upon to perform, about one-half, or more than half, proved fatal. Their mode of dressing other wounds was, moreover, at once clumsy and inefficient; and hence the mangled wretches who passed us this morning were not only suffering acutely from the natural effect of their hurts, but were put to more than ordinary torture on account of the clumsy and rude manner in which their hurts had been looked to.

Though I have no intention of writing a history of the campaigns of 1813 and 1814, it is necessary, for the purpose of rendering my journal intelligible, to give, in this stage of it, some account of the relative situations of the British and French armies.

The two kingdoms of France and Spain are divided, towards the shores of the Bay of Biscay, by the river Bidassoa—an inconsiderable stream, which, rising about the centre of the Peninsula, follows the winding course of one of those many valleys with which the Pyrenees abound, and falls into the sea near the ancient town of Fontarabia. The Bidassoa is perfectly fordable in almost all places, at the distance of ten miles from its mouth; whilst immediately opposite to Fontarabia itself there is one part where, at low tide, a passage may be effected, the water reaching only to the chest of him who crosses. About two or three miles from Irun, which is distant something less than a league from Fontarabia, is another ford, across which a bridge had been built, but which, at the period of my narrative, was in ruins; consequently, there were two separate fords leading to the pass of Irun, by both or either of which an army might advance with safety.

On either side of this little stream, the mountains, except at the passes of Irun, Roncesvalles, &c., rise so abruptly as to form an almost impassable barrier between the one kingdom and the other. The scenery of the Bidassoa is, in consequence, romantic and striking in the extreme; for not only are the faces of the hills steep and rugged, but they are clothed, here and there, with the most luxuriant herbage; whilst frequent streams pouring down from the summits, form, especially after rain, cascades that are exceedingly picturesque, and in some instances almost sublime. The river itself is clear, and rapid in its course—winding, as mountain streams generally do, where hills come in to impede their progress; and that it is not deficient in excellent trout, I am still a living witness, having, with my friend Captain Grey, more than once fished it.

At the period of which I am now speaking, the armies of Lord Wellington and Marshal Soult occupied the opposite banks of this little stream. Our pickets were stationed on the rise of the Spanish hills; those of the French on the faces of their own mountains; whilst the advanced sentinels were divided only by the river, which measured, in many places, not more than thirty yards across. But the French, whatever their faults may be, are a noble enemy. The most perfect understanding prevailed between them and us, by which not only the sentries continued free from danger, but the pickets themselves were safe from wanton surprisal; no attack upon an outpost being under any other circumstances thought of, unless it was meant to be followed up by a general engagement.

For myself, my situation was, as I have already stated, in a bleak valley, distant nearly three miles from the river, and surrounded on every side by bold and barren precipices. In such a place there was little either to interest or amuse; for of the French army we could see nothing; and of game, in quest of which I regularly proceeded, there was a woeful scarcity. There, however, we remained till the morning of the 5th, without any event occurring worthy of notice, unless a fortunate purchase of two excellent milch-goats, which I effected from a Spanish peasant, be deemed such. But on that day our position was changed; and the glorious scenery to which the march introduced us far more than compensated for the fatigues occasioned by it.

It is by no means the least pleasing circumstance in the life of a soldier upon active service that he never knows, when he awakes in the morning, where he is to sleep at night. Once set in motion, and, like any other machine, he moves till the power which regulates his movements shall call a halt; and wherever that halt may occur, there, for the present, is his home. Such a man has not upon his mind the shadow of a care; for the worst bed which he can meet with is the turf; and he seldom enjoys a better than his cloak or blanket. Give him but a tent—and with tents the commander of the forces had lately supplied us—and he is in luxury; at least as long as the summer lasts, or the weather continues moderate; nor had we as yet experienced any blasts against which our tents furnished not a sufficient shelter.

The sun was just rising on the morning of the 5th of September when our tents were struck, the line of march formed, and ourselves en route towards the base of one of the highest hills which hemmed us in on every side. Along the face of this mountain was cut a narrow winding path, for the accommodation, in all probability, of goatherds or muleteers, who contrive to transport articles of luxury and clothing into the wildest districts where human inhabitants are to be found. It was, however, so rough and so precipitous, as effectually to hinder our men from preserving anything like order in their ranks; and thus caused a battalion of little more than six hundred bayonets to cover an extent of ground measuring, from front to rear, not less than three quarters of a mile. Of course the fatigue of climbing, loaded as we were with arms, ammunition, and necessaries, was great; and as the heat of the day increased it became almost intolerable. But we toiled on in good spirits, hoping that each vale or level at which we arrived would prove the place of our rest, and not a little delighted with the romantic scenery to which every turning in the road introduced us.
