by the influence and eloquence of Pitt, would have carried the measure, but
for the skill and talent of a subaltern of artillery ; and that subaltern, who coped
successfully with a minister of state on a great national question, was Glennie.
The duke of Richmond, aware of Glennie's talents in the sciences of gunnery and fortification, frequently and anxiously endeavoured to obtain his approbation of his plans ; with more candour than wisdom, however, he not only steadfastly withheld this approbation, but unhesitatingly declared them to be absurd and impracticable. Glennie's early patron, the marquis of Townshend, knowing the former's opinion of the duke of Richmond's plans, invited him to his residence, where he detained him until he had composed, which he did at the marquis's request, a pamphlet on the subject. The pamphlet, which was written with great ability and discovered a profound knowledge of the matter of which it treated, was immediately published, and produced a prodigious effect. It instantly opened the eyes of the public to the absurdity of the minister's ideas : his projects were overturned, and the country was saved; but Glennie was ruined.
In this celebrated pamphlet, which is simply entitled "A Short Essay," it was demonstrated that extensive lines produce prolonged weakness, not strength, and showed that troops are much more formidable as an active and movable force, than as an inert body, cooped up in fortifications. It showed further, that the sum (calculated at 40 or 50 millions) which should be required to carry the duke's plans into effect, was more than would be necessary to build a new and complete fleet, superior to that of any power on earth. Besides all this, it was shown, that it would require 22,000 soldiers for the intended fortifications of Portsmouth and Plymouth alone.
Glennie, perceiving that all hopes of further promotion were now at an end, resigned his commission and emigrated to British America with his wife and children. Here he purchased a tract of land, and soon afterwards became a contractor for ship timber and masts for government. The speculation failed, and both Glennie himself, and a partner, a wealthy man who had joined him in it, were ruined. Driven back to England, but now, as many years had elapsed, forgotten and without friends, Glennie applied to the earl of Chatham, who recognizing his merits, but unable to do more for him, retained rather than employed him as "engineer extraordinary." Soon after, however, he procured Glennie the appointment of instructor to the East India Company's young artillery officers, with salary and emoluments amounting to 400 per annum. Glennie's good fortune was, however, again but of short duration. He was summoned as an evidence on some points in the celebrated trial of the duke of York and Mi's Clarke; his evidence was unfavourable to the duke; the consequence was, that he soon afterwards received an official letter from the board of directors, dispensing with his services.
In 1812, Glennie, now in the 62d year of his age, went out to Copenhagen at the request of a gentleman who then held a seat in parliament, to negotiate the purchase of a certain plantation. Glennie, having set out on his mission without coming to any explicit terms with his employer, his claim for compensation on his return was disputed, and referred to arbitration; but the referees could not agree, and the matter therefore was never adjusted. Glennie, now in an exceedingly destitute condition, without friends who could assist him, his health destroyed, and himself far advanced in life, made an unsuccessful attempt to procure a few mathematical pupils, and finally died of apoplexy on the 23d November, 1817, in the 67th year of his age. His remains were interred in the church-yard of St Martin's in the Fields.
Amongst other proofs of Glennie's geometrical knowledge is to be found a solution of Dr Matthew Stewart's "42d proposition on 39th theorem," which
