During the year 1799, the head-quarters remained at Stirling, and the recruiting went on but slowly.
1800.
In May 1800, the strength of the regiment amounted to about two hundred rank and file, when a route arrived changing the quarters to Paisley, but soon after the march an order arrived for its proceeding to Ireland. In June the regiment reached Portpatrick, and crossed immediately to Donaghadee, from whence it marched, under the command of Colonel Dalrymple, to Newry, and in a few days afterwards was removed to Dundalk.
In July the regiment received six hundred volunteers from the Scotch Fencible corps serving in Ireland, and remained at Dundalk until the close of the year, when a route for Dublin was received. At this period, Colonel Dalrymple was appointed brigadier-general, and the command of the regiment devolved on Brevet Lieut.-Colonel John French.
On the 6th of December Major Denis Pack was promoted from the fourth Royal Irish dragoon guards to be Lieutenant-Colonel in the Seventy-first regiment, in succession to Lieut.-Colonel the Honorable John Lindsay, who retired from the service.

The regiment, early in the year 1801, marched from Dundalk to Dublin, and occupied the barracks in the Palatine Square. On the 24th of April, Lieut.-Colonel Pack joined, and assumed the command of the regiment.
