KENNETH, EARL OF SEAFORTH. _Appointed Lieut.-Colonel Commandant 29th Dec. 1777_. Kenneth Mackenzie, grandson of William fifth Earl of Seaforth, who was deprived of his title and estates by act of attainder, for joining the rebellion headed by the Earl of Mar in 1715, adopted a line of conduct more consistent with the best interests of his country, than that pursued by his ancestors, and was a zealous supporter of the house of Hanover. He was created Baron of Ardelve in the county of Wicklow, and Viscount of Fortrose, in Scotland, in 1766, and advanced to the dignity of EARL OF SEAFORTH, in Ireland, in 1771. Grateful for these marks of royal favour, and anxious to promote the well-being of the kingdom, when Great Britain was engaged in war with the United States, and menaced by France, Spain, and Holland, he tendered his services to raise a regiment of Highlanders, now the SEVENTY-SECOND, of which he was appointed lieut.-colonel commandant by commission dated the 29th of December, 1777. His corps was soon fit for active service, and was admired for its warlike appearance. He embarked with it for the East Indies, and died on the passage in August, 1781, when his titles became extinct. THOMAS FREDERICK MACKENZIE HUMBERSTON. _Appointed Lieut.-Colonel Commandant, 13th Feb. 1782_. Thomas Frederick Mackenzie Humberston, grandson of Colonel the Honorable Alexander Mackenzie, second son of Kenneth fourth Earl of Seaforth, was appointed Cornet in the first dragoon guards in June, 1771; in 1775 he was promoted to a Lieutenancy, and in 1777 to Captain of a troop in the same corps. He took great interest in the formation of the Highland corps raised by his cousin, the Earl of Seaforth, now the SEVENTY-SECOND, or the Duke of Albany’s Own Highlanders, in which regiment he was appointed Captain in January, 1778, and Major in March, 1779. He was quartered with his regiment at Jersey, and took an active share in repulsing the attempt made by a body of French troops to land on that island on the 1st of May, 1779. He afterwards took an active part in the formation of another corps of Highlanders, which was numbered the 100th regiment, of which he was appointed Lieut.-Colonel Commandant on the 5th of August, 1780. Soon after its formation, the 100th regiment was selected to form part of an expedition against the Cape of Good Hope, and its commandant had the local rank of Colonel in the expedition; the naval part of the enterprise was under the direction of Commodore Johnstone. While the fleet was at Praya Bay, in St. Jago, one of the Cape de Verd Islands, it was suddenly attacked by a French squadron; Colonel Humberston happened to be on shore at the time; but so great was his ardour to share in the enterprise, that he swam to one of the ships that was engaged with the enemy, who was repulsed. In the meantime the Dutch garrison at the Cape had been reinforced, the project of attacking that colony was laid aside, and Colonel Humberston proceeded with the land
