To these circumstances the SECOND BATTALION of the SIXTY-SEVENTH regiment owes its origin, and the battalion was formed of men raised in Ireland, for limited service under the provisions of the "Army of Reserve Act," which was passed in June, 1803; the battalion was placed on the establishment from the 9th of July following. [Sidenote: 1804] The _Second Battalion_ was also authorised to receive men raised in Ireland, for limited service, under the "_Additional Force Act_," which was passed on the 14th of July, 1804. The battalion was stationed in Ireland until the 20th of January, 1804, when it embarked at Warren's Point, and arrived at Greenock on the 23rd of the same month. [Sidenote: 1807] On the 29th of February, 1804, the battalion proceeded to Guernsey, where it remained until the 17th of November, 1807, when it was removed to Alderney. [Sidenote: 1810] From Alderney the battalion returned to Guernsey in July, 1810. Six companies of the battalion, under the command of Lieutenant-Colonel William Prevost, embarked for Gibraltar on the 29th of July, 1810, at which station they arrived on the 24th of September. The four companies left at Guernsey, embarked for England in August, 1810, where they continued to be stationed during the remainder of that year. The six companies of the second battalion remained at Gibraltar until the 22nd of November, 1810, when they embarked for Cadiz, to join the army under the command of Lieutenant-General Thomas Graham, afterwards Lord Lynedoch. The six companies arrived at Cadiz on the 9th of December, 1810, which was at that period besieged by a powerful French army, under Marshal Soult, who subsequently proceeded on an expedition into Estremadura, leaving Marshal Victor to blockade Cadiz. [Sidenote: 1811] The SIXTY-SEVENTH remained at Cadiz until the 18th of February, 1811, when they proceeded with the army under the command of Lieutenant-General Thomas Graham, which consisted of a British force of about three thousand, and a body of seven thousand troops commanded by General La Pena. The design of the expedition was to make a combined attack on the rear of the French army blockading Cadiz. The forces disembarked at Algesiras on the 23rd of February, and being all united at Tarifa, marched from thence on the 28th of February. General Zayas pushed a strong body of Spanish troops across the river Santi Petri, near the coast, on the 1st of March, threw a bridge over, and formed a _tête-de-pont_. This post was attacked by the enemy on the nights of the 3rd and 4th of March, who was repulsed, though the Spaniards sustained considerable loss. On the 5th of March, 1811, Lieutenant-General Graham and the army under his command arrived on the low ridge of _Barrosa_, where a brilliant victory was gained over the French army under Marshal Victor, composed of the two divisions of Generals Rufin and Laval.
