In November, 1825, the regiment was reunited in the Royal Barracks at Dublin, where it continued until May, 1826, when, in consequence of riots in the manufacturing towns in Lancashire and Yorkshire, it was ordered to proceed to England. The head-quarters were fixed at Halifax, and detachments were sent to Huddersfield, Bradford, and to various other towns. Tranquillity being restored in the above counties, the regiment was ordered to return to Dublin in July, 1826, and from thence it proceeded in August to occupy its former quarters at Naas, and the outposts. In December following, the regiment received orders to march to Waterford, furnishing detachments at Kilkenny, Wexford, Carrick-on-Suir, and Duncannon Fort. [Sidenote: 1827] In August, 1827, the regiment was ordered to Fermoy, preparatory to embarkation, where in the course of the month, the service and depôt companies were formed. The service companies embarked at Cove for Gibraltar towards the end of August and beginning of the following month, and arrived at their destination on the 10th, 17th, and 24th of September. The depôt companies remained in Ireland during this and the two following years. [Sidenote: 1828] During the prevalence of the contagious and dreadful fever which visited Gibraltar in the year 1828, the SEVENTY-THIRD were encamped with the twenty-third Royal Welsh Fusiliers on Europa Flats, from the 10th of October to the 17th of January, 1829. [Sidenote: 1829] The casualties in the SEVENTY-THIRD were, compared with the other regiments in that garrison, fortunately limited to a small number. Out of nine officers and one hundred and ninety-six privates, who were attacked with the disease, only two officers and thirty-five men proved fatal cases. Lieutenant Hedworth Huddleston Williamson, and Assistant Surgeon John Gordon Fraser were the officers; the latter, though a very young assistant, fell a victim to his zeal for the service. Whether the comparatively few casualties were attributable to the successful practice of the Surgeon George Martin, or some other accidental cause, can be only matter of conjecture. One thing, however, is certain, that His Excellency the Lieutenant-Governor, as well as numerous other officers unconnected with the regiment, acknowledged, in the most public manner, the talents and attention of Surgeon Martin, of the SEVENTY-THIRD, on this trying occasion. Major-General Sir Frederick Adam, K.C.B., was appointed colonel of the SEVENTY-THIRD regiment on the 22nd of May, 1829, in succession to General George Lord Harris, G.C.B., deceased. In December, 1829, the service companies embarked for Malta, where the last division arrived on the 31st of that month. On the departure of the SEVENTY-THIRD from Gibraltar, His Excellency the Lieut.-Governor, General Sir George Don, G.C.B., issued the following order:-- “_Head Quarters, Gibraltar, 2nd December, 1829._
