Salamanca, 25 June 1812.

My Dearest Father,

I have been too constantly occupied since the 17th to write even a few lines to anybody. I gave in my letter of that date some account of our advance to this place....

We have had a most interesting though harassing time of it since I wrote. On the 18th we began to fire at the Fort, from a Convent near it, with field-pieces, and next day, finding it much stronger than was expected, 4 iron 18 Prs. were mounted, which knocked down very soon one end of the Convent, but the works, which we found to be by no means so easily forced, were not at all injured, and the enemy seemed determined to make a gallant resistance. On the 19th, in the morning, accounts arrived that Marmont and his whole army were advancing in sight. The 6th Division under Clinton was therefore left to carry on the attack of the Forts, and the rest of the army assembled in a position tolerably strong for an army of equal strength, the left near St Christoval de la Cuesta extending in rear of Castillejos de Morisco and Morisco towards the Tormes, from which our right, however, was some distance, though the ground is strong and we could easily move to it if all attacked in that direction. The Spanish Corps of about 3000 men under Don Carlos d’Espanha, and 800 Cavalry Guerrillas under Dn. Julian Sanchez, were on our left on some strong ground in continuation of our line.

On arriving there we distinctly saw the French army advancing towards us from Toro, by Aldea Nueva, Archidiacono, etc., etc., in heavy columns of Infantry with a strong advance guard, and about 3000 Cavalry.

The day was very unfavourable, as we had heavy rains and thunderstorms, which however have cooled the air, and since been of great use to us. During the night of the 20th the enemy advanced, and occupied the ground within cannon range of our position, and the villages of Castillejos and Morisco, concealing their numbers by the inequalities of the ground, and certainly giving us every occasion to believe they had come down determined to fight, which everybody was glad of, as it would save a great deal of trouble in going after them, away from our resources, and which we could not do till we had taken the Fort in the Town, which completely commands and prevents our making any use of the Bridge.

Nothing, however, was done on the 20th, except a pretty brisk cannonade towards evening on both sides, though it did not last long. We lost a few horses of the Heavy Dragoons, and there was some skirmishing on the right with the 11th Lt. Dns. and 1st German Hussars.

On the 21st the enemy continued all day to receive very strong reinforcements. We were so close, and overlooked their position so completely, that we could see everything that entered their lines and every movement they made.

Everybody expected that they would have attacked next morning, as it was known that Marmont had received every succour he could, except Bonnet’s Division from the Asturias, which was not expected to be coming up, but we were again disappointed. They only occupied a small hill on our right near Morisco, which overlooked our position, but from which they were driven by part of the 7th Division, which cost about 60 or 70 killed and wounded, but the enemy’s Cavalry and Infantry must have suffered a good deal from our cannonade and musquetry, as they were very close to each other. The enemy seemed jealous of their left flank, which was not at all secure, and moved the greater part of his Cavalry, and a column of Infantry to strengthen it, but nothing more was done, except that our Cavalry chased Marmont, who had advanced a good way to our left to reconnoitre, but he had some Infantry with him and they could do nothing against it. The enemy fired a few cannon shot at them, which did very little harm.

The next morning, to our great surprise, we found the enemy had retired, and when the day broke saw them moving off at a short distance towards our Right, and then halted on some heights, about 6 miles in front of our position. The Cavalry was sent forward to pursue them, and took up a line of vedettes very near them. Lord Wellington and the Marshal rode out to reconnoitre them, but I do not think anybody could make out anything of their intentions. We were very close to them, and they appeared to be halted near Aldea Rubia, and Morréra, to allow their baggage to move off to the rear, which, however, does not seem to have been the case, for they are still there.
