The battalion marched to Azumar on the 8th of May, and on the 13th to Arronches, from which it moved towards the end of the month to Puebla, in Spain, then to Badajoz, where it halted five days, thence to Castello de Vide for two days, from which it marched through Castello Branco in the direction of Salamanca, which it reached on the 17th of June, and operations were then immediately commenced against the Forts at Salamanca by the light companies of the division under Colonel Samuel Venables Hinde, of the Thirty-second regiment. They were attacked without success on the 23d, and carried on the 27th of June by a party under the command of Lieut.-Colonel Davies, of the THIRTY-SIXTH, with a loss to the battalion of Lieutenant George Mackenzie and eleven rank and file killed, and Captain Paul Minchin Hobart and twenty-five rank and file wounded. Captain Hobart, who was promoted to the brevet rank of Major on the 23d of July 1812, died of his wounds. The battalion then occupied different villages in the neighbourhood, and on the 22d of July it took a considerable share in the battle of Salamanca. The change of the allied position and various manœuvres occupied the day without any close engagement, excepting on the left for the possession of the Arapiles; the battle of _Salamanca_ did not commence in earnest until after three o’clock, when the French left, having been very much extended by the advance of the division of General Thomières, with the light cavalry and fifty pieces of artillery, along a range of heights parallel with the British line, to cut off the right of the allies from the Ciudad Rodrigo road, the third division was ordered to advance in four columns, supported by cavalry to turn the French left. The evolutions of this great battle are too varied to be clearly described with brevity. The sixth division under Major-General Clinton, of which the THIRTY-SIXTH formed part, was placed at first in reserve, but at a critical period in the action it was ordered up to relieve the fourth division, and the battle was soon restored to its former success. The enemy’s right, reinforced by the troops which had fled from his left, and by those which had by this time retired from the Arapiles, still continued to resist; and while other corps were directed to turn the right, the sixth division, supported by the third and fifth, attacked the front. It was dark before this point was carried by the sixth division, and the enemy then fled through the woods towards the Tormes. Lieut.-General Sir William Napier, in his History of the Peninsular War, thus sums up the account of this victory:-- “The battle of Salamanca, remarkable in many points of view, was not least so in this, that it was the first decided victory gained by the allies in the Peninsula. In former actions the French had been repulsed, here they were driven headlong, as it were, before a mighty wind, without help or stay, and the results were proportionate.”
