In July the THIRTEENTH, in brigade with the ninth dragoons and second German hussars, were engaged in a second successful affair with the enemy at _Usagre_; and in one of the several skirmishes, _Serjeant Shaw_ of the THIRTEENTH distinguished himself by his gallantry. Honourable mention is also made of the firm and orderly retreat of a squadron of the regiment, commanded by Captain SHAPLAND BOYSE, before a vastly superior body of the enemy's cavalry, by whom they were hard pressed for a considerable distance in the neighbourhood of Ocana. A singular circumstance occurred when the regiment was bivouacked in the neighbourhood of Aranjuez: the horses, being unbridled for the convenience of feeding, were linked, and the officers and men were reposing from their fatigues, when the Second German Hussars, who had been ordered to join Lord Wellington's army, filed past; the THIRTEENTH immediately sprung up, and actuated by the impulse of the moment, greeted their old comrades with a hearty parting cheer, which so alarmed the horses that four troops broke loose, notwithstanding every exertion made to detain them, and dispersed over the open country, galloping about in squads, and scattering bridles, pistols, carbines, &c., in every direction. The scene was truly ludicrous; but this inconsiderate act might have been attended with serious consequences, as the enemy was in force, particularly in cavalry, in Aranjuez. The horses, some of which had strayed to a distance of four or five leagues, and had been secreted by the Spaniards, were all brought back in the course of the day, and scarcely an article of equipment was lost. The exertions of Adjutant Holmes on this occasion are particularly mentioned. At the close of the campaign, when the main army withdrew from Burgos, the troops under Lieut.-General Hill also fell back, and the whole were united at Salamanca. The THIRTEENTH were in reserve in the affair at Alba de Tormes, and were engaged, with the rear guard, in skirmishing with the enemy during the retrograde movement of the army to the Agueda. The horses suffered severely from want of forage. After retiring beyond the confines of Spain, the regiment marched to the Alemtejo, and was quartered at Crato, where it received a reinforcement of officers, men, and horses, from England in December. [Sidenote: 1813] In February, 1813, the regiment was removed from Crato to Monforte, where it received a draught of one hundred and thirty-six horses from the Ninth Dragoons, who were ordered to return to England; at the same time a serjeant and ten men were attached to the staff corps of cavalry.
