The second battalion was employed on garrison duty in the island of Jersey until the power of Napoleon Bonaparte was overthrown by the armies of the allies, and the Bourbon family was restored to the throne of France, which was accompanied by the restoration of peace to Europe. A reduction was, in consequence, made in the strength of the British army, and the second battalion of the ROYAL IRISH regiment was disbanded at Jersey on the 24th of October 1814, transferring its non-commissioned officers and private soldiers fit for duty to the first battalion.
1817
After twelve years' service in Jamaica, during which time it had suffered severely from the effects of climate, and had lost upwards of fifty officers and nearly three thousand non-commissioned officers and soldiers, the ROYAL IRISH regiment received orders to return to England. It landed at Portsmouth in March, 1817, in so complete a state of discipline and efficiency, that it was ordered to proceed to Brighton, where it had the honour of furnishing the usual guard for the Prince Regent during His Royal Highness' stay at the Pavilion. The regiment was afterwards removed to Chatham and Sheerness, and in August it proceeded to Hilsea barracks.
1818
Early in 1818 the ROYAL IRISH regiment marched to Haslar barracks and Gosport; in December it embarked for Ireland, and, after landing at Cork, proceeded to Fermoy.
1819
From Fermoy the regiment marched, in January, 1819, to Waterford, Wexford, Carlow, Duncannon-fort, and Kilkenny; and the excellent conduct of the men, during their stay in these quarters, elicited the admiration and gratitude of the public authorities of the several places, which was communicated to the corps in the strongest terms.
1820
In July, 1820, the regiment marched to Cork.
