From “A Military History of Perthshire”

In 1755 he was promoted major-general, and in 1758 lieutenant-general, but although he offered his services more than once, he was not employed abroad during the Seven Years’ War. He took the keenest interest, however, in all the exploits of his regiment and worked hard to raise a second battalion in 1758. Stewart of Garth tells us that when the men who had been disabled at Ticonderoga appeared before the Board of Chelsea to claim their pensions, Lord John went with them and explained their case in such a manner to the commissioners that they were all successful. He gave them money, got them a free passage to Perth, and offered a house and garden to all who chose to settle on his estate. General Stewart also describes how, when the 42nd at last returned from America in 1767, Lord John, who had been for weeks at Cork awaiting its arrival, marched into that town at its head.

Lord John was a great deal with the regiment while it was quartered in Ireland, and, according to Stewart of Garth, was “ever attentive to the interest of the officers and vigilant that their promotion should not be interrupted by ministerial or other influence.” He was also “unremitting in his exertions to procure the appointment of good officers, and of officers who understood perfectly the peculiar dispositions and character of the men.” For this reason he strenuously endeavored to exclude all but the members of Scots—and more especially Highland—families. He was equally particular that only Gaelic-speaking men and Protestants should be recruited for the ranks.

In spite of his military duties Lord John resided a good deal in the country—and not only at the home of his boyhood—for early in life he bought Pitnacree in Strathtay, and in later years he had also a house in Perth. He represented Perthshire in Parliament from 1734 to 1761. In 1758 he married Miss Dalton of Bannercross—a Derbyshire heiress, by whom he had one daughter. In 1770 he became a full general. His last military achievement was the raising in 1779 and 1780 (at his own expense) of another second battalion to the 42nd. This battalion so distinguished itself in India that in 1786 it was placed permanently on the establishment under the title of the 73rd Regiment. The veteran to whose patriotism it owed its existence died on the 26th day of May, 1787, at the age of seventy-six, the senior officer in the Army.

Lord John made the most of such chances as occurred of distinguishing himself in the field, but those opportunities were small for he never served in any war but the Austrian Succession. It is therefore as the Colonel of the Black Watch that his name has survived—as a man who understood the Highland soldiers well enough to wish to command them at a time when to many that might have seemed a task of great difficulty—and who, having at last obtained the post he desired, completely identified himself with the interests of his men, and for upwards of half a century was the “friend and supporter of every deserving officer and soldier in the regiment.”

John Reid.

John Reid was the eldest son of Alexander Robertson of Straloch, but the head of the family had always been known as “Baron Reid” and the General and his younger brother, Alexander (who was an officer in the 42nd), adopted the more distinctive surname early in life. He was born at Inverchroskie in Strathardle, on the 13th of February, 1721, and received his early education at Perth. Being destined for the law, he was afterwards sent to Edinburgh University. Nature, however, had intended him for a soldier, and in June, 1745, having recruited the necessary quota of men, he obtained a commission as lieutenant in Loudon’s Highlanders. He was taken prisoner at Prestonpans the following September, but when released the following spring he rejoined his regiment and was able to render important service to the Government. From 1747 to 1748 he served in Flanders with Loudon’s Highlanders and took part in the defence of Bergen-op-Zoom, but on the reduction of his regiment at the Peace of Aix-la-Chapelle he was placed on half-pay. In 1751 he bought a captain-lieutenant’s commission in the Black Watch and in 1752 a commission as captain in the same regiment. Four years later on the outbreak of the war with France, he sailed with his regiment to America. He was not present at the first attack on Ticonderoga as he had been left behind sick at Albany, and his company was commanded in that desperate engagement by Captain James Murray. In 1759, Reid, by that time a major, took part in the second advance to Lake Champlain, which resulted in the surrender of Forts Ticonderoga and Crown Point; and on him devolved the command of the 42nd during the greater part of the campaign of 1760 which ended with the capture of Montreal and the expulsion of the French from Canada.

Reid remained in America with the 42nd until Dec., 1761, when he accompanied it to the West Indies. He served in the capture of Martinique and at the storming of Morne Tortenson, on Jan. 24, 1762, was in command of the 1st Battalion of his regiment. His battalion suffered heavy loss and he was wounded in two places, but recovered in time to take part in the expedition against Havana of that same year. After the surrender of Cuba he returned to America. In 1764 Reid acted as second-in-command of Colonel Bouquet’s arduous but successful expedition against the Indians on the Ohio and Muskingum Rivers. In the following year we hear of him fitting out an expedition which was to be sent to the Illinois country under the command of Captain Thomas Stirling of the 42nd.

About 1760, Reid married an American lady of Scots descent, Susanna Alexander, daughter of James Alexander, surveyor-general of New York and New Jersey. She owned property on Otter Creek in what is now the State of Vermont, which was added to and improved by her husband with the result that at the end of ten years Reid owned “about thirty-five thousand acres of very valuable land” near Crown Point and had “obtained from the Governor and Council of New York a warrant of survey for fifteen thousand more,” which he intended to “erect” into a manor.
