On the following day the regiment went in pursuit of the remains of the French army, and on the 24th of June, fell in with the rear-guard at a pass about two leagues from _Pampeluna_, when two battalions of riflemen drove the French infantry through the pass, the horse artillery killed several men, and dismounted one of the two pieces of cannon brought off from Vittoria; at the same time the leading squadron of the FOURTEENTH, under Major Brotherton, charged and captured a tumbril. The French withdrew into the passes of the Pyrenean mountains; the FOURTEENTH light dragoons followed the enemy, and on the 28th of June, a patrol of three men of the regiment, under Lieutenant Ward, penetrating to the village of _Ostiz_, found twenty-five French foot soldiers regularly armed and formed up at the village, who surrendered themselves prisoners of war. Advancing further into the mountains, a patrol of six men of the regiment, commanded by Lieutenant Clavering, encountered, on the 1st of July, a body of infantry of the French rear-guard, on the road from _Roncesvalles_ to St. Jean-Pied-de-Port, dispersed them, and took eighteen prisoners. A strong body of French troops occupied the fruitful valley of _Bastan_, in the mountains, from whence they were driven by the troops under Sir Rowland Hill. The FOURTEENTH were attached to Lieut.-General Hill's division, and a squadron, under Major Brotherton, was engaged, on the 4th of July, with a body of the enemy near _Almandoz_. The allied army was established in positions in the mountains; the FOURTEENTH took the out-post duty in front of Maya, and also furnished posts of correspondence for several weeks. At length, the French army having been reinforced, re-organized, and placed under the command of Marshal Soult, advanced and commenced offensive operations. During the action of the 26th of July, the regiment was employed in carrying off the wounded from the pass of Maya, and received the thanks of Sir Rowland Hill. A squadron under Captain Milles was similarly employed on the 30th of July, when Sir Rowland Hill's post at _Arestegui_ was attacked, and another squadron under Major Brotherton had a rencounter with the enemy. The French having been repulsed, fell back in disorder, and were pursued to the confines of Spain. The FOURTEENTH formed the van of Sir Rowland Hill's division, and were engaged with the enemy in the valley of _Bastan_, on the 1st and 2nd of August: on the 5th the regiment took the out-post duty in front of Maya.
