On the 27th, we encamped on the banks of the Tormes, at a ford, about a league below Salamanca. A body of the enemy, who had occupied the city, suffered severely before they got away, in a brush with some part of Sir Rowland Hill's corps; chiefly, I believe, from some of his artillery.

On the 28th, we crossed the river, and marched near to Aldea Nueva, where we remained stationary for some days, under Sir Rowland Hill; Lord Wellington having proceeded from Salamanca to join the left wing of the army, beyond the Douro.

On the 2d of June, we were again put in motion; and, after a very long march, encamped near the Douro, opposite the town of Toro.

Lord Wellington had arrived there the day before, without being opposed by the enemy; but there had been an affair of cavalry, a short distance beyond the town, in which the hussar brigade particularly distinguished themselves, and took about three hundred prisoners.

On the morning of the 3d, we crossed the river; and, marching through the town of Toro, encamped about half a league beyond it. The enemy had put the castle in a state of repair, and constructed a number of other works to defend the passage of the river; but the masterly eye of our chief, having seen his way round the town, spared them the trouble of occupying the works; yet, loth to think that so much labour should be altogether lost, he garrisoned their castle with the three hundred taken by the hussar brigade, for which it made a very good jail.

On the 4th, we were again in motion, and had a long, warm, fatiguing march; as, also, on the 5th and 6th. On the 7th, we encamped outside of Palencia, a large rickety looking old town; with the front of every house supported by pillars, like so many worn out old bachelors on crutches.

The French did not interfere with our accommodation in the slightest, but made it a point to leave every place an hour or two before we came to it; so that we quietly continued our daily course, following nearly the line of the Canal de Castile, through a country luxuriant in corn-fields and vineyards, until the 12th, when we arrived within two or three leagues of Burgos, (on its left,) and where we found a body of the enemy in position, whom we immediately proceeded to attack; but they evaporated on our approach, and fell back upon Burgos. We encamped for the night on the banks of a river, a short distance to the rear. Next morning, at daylight, an explosion shook the ground like an earthquake, and made every man jump upon his legs; and it was not until some hours after, when Lord Wellington returned from reconnoitring, that we learnt that the castle of Burgos had been just blown up, and the town evacuated by the enemy.

We continued our march on the 13th, through a very rich country.

On the 14th, we had a long harassing day's march, through a rugged mountainous country, which afforded only an occasional glimpse of fertility, in some pretty little valleys with which it was intersected.

We started at daylight on the 15th, through a dreary region of solid rock, bearing an abundant crop of loose stones, without a particle of soil or vegetation visible to the naked eye in any direction. After leaving nearly twenty miles of this horrible wilderness behind us, our weary minds clogged with an imaginary view of nearly as much more of it in our front, we found ourselves, all at once, looking down upon the valley of the Ebro, near the village of Arenas, one of the richest, loveliest, and most romantic spots that I ever beheld. The influence of such a scene on the mind can scarcely be believed. Five minutes before we were all as lively as stones. In a moment we were all fruits and flowers; and many a pair of legs, that one would have thought had not a kick left in them, were, in five minutes after, seen dancing across the bridge, to the tune of "the downfal of Paris," which struck up from the bands of the different regiments.
