On the morning of the memorable 21st of June, 1813, the SIXTH moved from their camp on the river Bayas, and traversed the mountains in the direction of _Vittoria_, to engage in the attack of the enemy's formidable position; but so rugged was the country, and the tracts along the hills so difficult, that the battle was raging with great violence when the division, led by the Earl of Dalhousie, arrived at their appointed station. They were, however, in time to take part in forcing the passage of the Zadora; and the seventh division, with one brigade of the third, having passed the river, formed the left of the British line, and were engaged with the French right in front of the villages of Margarita and Hermandad. Finally a complete and most decisive victory was gained. The conduct of the Earl of Dalhousie and his division was commended in the public despatch; the commanding officer of the SIXTH, Lieut.-Colonel Archibald Campbell, was presented with a gold medal, and the gallantry of the regiment was rewarded with the honour of bearing the word "VITTORIA" inscribed on its colours. The SIXTH moved forward in pursuit of the wreck of the French army in the direction of Pampeluna; but were subsequently detached against a division of the enemy under General Clausel, who was not at the battle, and had taken post at Logroño, from whence he made a precipitate retreat to Saragossa, and effected his escape by the pass of Jaca. After returning from this enterprise the regiment penetrated the _Pyrenean_ mountains; and the light and seventh divisions occupied the heights of Santa Barbara, the town of Vera, and the Puerto de Echalar, and communicated with the troops in the valley of Bastan. The French army, having been re-organised under Marshal Soult, attacked the British posts on the 25th of July. The SIXTH, with the remainder of their brigade, moved forward to support two brigades of the second division which had been forced from their ground at the head of the valley of Bastan, and the enemy was driven back with loss. But the brigades in Roncesvalles having been obliged to retire, the troops in the valley of Bastan also fell back to a very strong post in the mountains behind Irueta. The regiment lost several men on this occasion, and had Major Gomm and Ensign Radcliff wounded. Its conduct, with that of the other corps engaged, was commended by the Marquis of Wellington, who observed in his despatch:--"Notwithstanding the enemy's superiority of numbers, they acquired but little advantage over these brave troops during the seven hours they were engaged. All the regiments charged with the bayonet."
