From the deservedly high character borne by the captain of the frigate which I was ordered to join, he was employed by Lord Collingwood on the most confidential services; and we were sent to assist the Spaniards in their defence of the important fortress of Rosas, in Catalonia. It has already been observed that the French general, St Cyr, had entered that country, and, having taken Figueras and Gerona, was looking with a wistful eye on the castle of Trinity, on the south-east side, the capture of which would be a certain prelude to the fall of Rosas. My captain determined to defend it, although it had just been abandoned by another British naval officer, as untenable. I volunteered, though a supernumerary, to be one of the party, and was sent: nor can I but acknowledge that the officer who had abandoned the place had shown more than a sound discretion. Every part of the castle was in ruins. Heaps of crumbling stones and rubbish, broken gun-carriages, and split guns, presented to my mind a very unfavourable field of battle. The only advantage we appeared to have over the assailants was that the breach which they had effected in the walls was steep in its ascent, and the loose stones either fell down upon them, or gave way under their feet, while we plied them with every kind of missile: this was our only defence, and all we had to prevent the enemy marching into the works, if works they could be called. There was another and very serious disadvantage attending our locality. The castle was situated very near the summit of a steep hill, the upper part of which was in possession of the enemy, who were, by this means, nearly on a level with the top of the castle, and, on that eminence, three hundred Swiss sharpshooters had effected a lodgment, and thrown up works within fifty yards of us, keeping up a constant fire at the castle. If a head was seen above the walls, twenty rifle-bullets whizzed at it in a moment, and the same unremitted attention was paid to our boats as they landed.
