RICHARD LAMBART, son of the Honorable Henry Lambart, third son of Charles third Earl of Cavan, served in the army in the war of the Austrian succession, and in June, 1756, he was promoted to captain and lieut.-colonel in the first foot guards. He was advanced to the rank of colonel in 1762, and to that of major-general in 1772; he succeeded to the dignity of EARL OF CAVAN in the same year. In 1774 he was appointed colonel of the fifty-fifth regiment; and was removed to the FIFTEENTH in the following year: in 1777 he was promoted to the rank of lieut.-general. He died in November, 1778. SIR WILLIAM FAWCETT, K.B. _Appointed 12th November, 1778._ WILLIAM FAWCETT, descended from the ancient family of Fawcetts, of Shipden Hall, near Halifax, having, from his early youth, a strong predilection for a military life, his friends procured him an ensign's commission in General Oglethorp's regiment, which was stationed in Georgia; but a British force having been sent to Flanders in 1742, he resigned his commission, proceeded to the continent, and, serving as a volunteer, was at the battles of Dettingen and Fontenoy, where his gallantry attracted admiration; and he was appointed ensign in a regiment raised by Colonel Johnstone, with which he served until the peace of Aix-la-Chapelle, in 1748, when it was disbanded. Being now unemployed, he engaged in the service of a mercantile establishment in the city of London; but finding his propensity to a military life invincible, he subsequently purchased an ensign's commission in the foot guards, and, by a strict attention to his duties, procured the favour of his Royal Highness William Duke of Cumberland, who gave him the adjutancy of the second battalion of the third foot guards, which he held together with a lieutenantcy, which gave him the rank of captain. Neglecting no opportunity of qualifying himself for the highest posts in his profession, he studied the German and French languages, acquired a knowledge of Prussian and French tactics; and in 1757 published a translation of the 'Memoirs upon the Art of War, by Marshal Count de Saxe,' and 'The Regulations for Prussian Cavalry;' and, in 1759, 'Regulations for the Prussian Infantry,' and 'The Prussian Tactics.' These works met with great attention, and a new edition in 1760 was also well received.
