In the attack on the enemy's lines, on the 8th January, 1815, the two squadrons served dismounted. Major-General the Honourable Sir Edward Pakenham, K.C.B., was killed; Major-Generals Gibbs and Keane were dangerously wounded; and the command devolved on Major-General Lambert, who stated in his public despatch, 'The conduct of the two squadrons of the FOURTEENTH light dragoons, latterly under the command of Lieut.-Colonel Baker, previously of Major Milles, has been the admiration of every one, by the cheerfulness with which they have performed all descriptions of service.' The troops returned on board the fleet; and one boat, containing Lieutenant Brydges, Cornet Hammond, one serjeant-major, and thirty-nine rank and file of the regiment, was captured by the Americans. Hostilities were soon afterwards terminated by a treaty of peace; and the two squadrons arrived in England, and joined the regiment at Hounslow in May; a third squadron which had embarked for America, also rejoined the head-quarters. This year the regiment was authorized to bear the word "PENINSULA" on its guidons and appointments, in commemoration of its services in Portugal, Spain, and France. Napoleon Buonaparte having quitted Elba, and returned to France, and having regained the throne of that kingdom, war was immediately recommenced; three squadrons of the FOURTEENTH having sailed for America, the regiment was prevented sharing in the contest which followed; but Colonel Hervey and Major Percy served on the staff of Field-Marshal the Duke of Wellington. [Sidenote: 1816] In December the regiment embarked at Bristol for Ireland, and landed at Waterford and Cork in January, 1816: at the same time the establishment was reduced to eight troops. [Sidenote: 1817] [Sidenote: 1818] A further reduction took place in the two following years; and in 1818 Captains Townsend and Badcock received the rank of major in the army for services in the field during the Peninsular war. [Sidenote: 1819] During its stay in Ireland the regiment was several times commended for its conduct and discipline by Major-General White, and Major-General Sir Sydney Beckwith: and on the 27th of May, 1819, it was formed in column and received the personal thanks of Sir George Beckwith, commanding the forces in that part of the United Kingdom. The regiment embarked from Dublin in June, and landed at Liverpool on the 11th of that month.
