After passing several months in quarters in Estremadura, the second battalion of the THIRTY-FOURTH advanced, in May, 1813, with the troops under Sir Rowland Hill, upon Salamanca, thus taking part in the comprehensive movements by which the enemy’s position on the Douro was turned, and the French divisions forced to retreat. The THIRTY-FOURTH followed the enemy in his retrograde movements, advancing upon Valladolid, and afterwards upon Burgos, and on the 12th of June the battalion took part in forcing a strong body of French troops from _Hormaza_; which was followed by the destruction of Burgos Castle, and the retreat of the enemy behind the Ebro river. The battalion took part in the movement through the wild and beautiful regions towards the source of the Ebro, and after traversing rocks, and mountains, and narrow defiles, it crossed the Ebro; when the enemy again fell back, and Joseph Bonaparte concentrated his force in the valley of _Vittoria_, to arrest the progress of the British arms. After taking part in these brilliant operations, the THIRTY-FOURTH had the honor to contribute to the complete overthrow of the French army on the 21st of June. On this occasion the battalion formed part of the column under Lieutenant-General Sir Rowland Hill, which advanced at day-break, and seizing the bridge of Puebla, crossed the Zadora river; the Spaniards under General Morillo attacking the heights of La Puebla, and the British advancing along the Vittoria road. The French commander sent a strong body of troops to regain the heights, and two British battalions were detached to aid the Spaniards. Before the fighting at this point had ceased, Sir Rowland Hill’s column issued fiercely from the defiles of Puebla, and captured the village of Sabijana de Alava. The heights at this point, some thickly wooded ground, and the village, became the theatre of a severe contest, in which the THIRTY-FOURTH, under Lieutenant-Colonel Fenwick, were warmly engaged. The troops advanced under a heavy cannonade; but undismayed by the determined countenance of the foe, and regardless of a shower of bullets, the British infantry rushed forward, dislodged the enemy, and drove him back on his reserve. In vain the French endeavoured to recover the lost ground; columns of attack were formed, and repeated efforts made; but all without success. The other columns of the allied army were also victorious at their several points of attack, and the legions of Napoleon sustained a decisive overthrow; they were driven from the field with the loss of their artillery, baggage, and military chest, and were pursued until dark. The THIRTY-FOURTH had ten rank and file killed; Lieutenants T. G. Ball, Edward Mogridge, and Alan B. Cairnes, four serjeants, and fifty-nine rank and file wounded.
