Gravel Pits, then a rural village, on Sunday, 17 July 1726. In accordance with a wish expressed in his will he was buried privately at night in Henry VII's Chapel in Westminster Abbey, on the Thursday following his decease. A notice of his death appears in ‘Lettres Historiques’ for September 1726 (Hague), and some memoranda relating to his Dutch estates are among the Port and papers in the British Museum (Egerton MS. 1708, f. 43 .
Personally Cadogan was a big, burly Irishman. A portrait, painted by Laguerre, representing him in a light-coloured wig and a suit of silver armour worn over his scarlet uniform, is in the National Portrait Gallery. Horatio, lord Walpole, who was associated with him in some of his diplomatic missions at the Hague, describes him as rash and impetuous as a diplomatist, lavish of promises when a present difficulty was to be removed, and prone to think that pen and sword were to be wielded with equal fierceness. He also says that Cado an needlessly irritated the Dutch republic by his zeal in romoting the election of the Prince of Orange to the Stadtholdership of Groningen, and affronted the citizens of Antwerp by threatening in convivial moments to make them follow their neighbours’ example (Coxe, Life of Lord Walpole, pp. 9-10). Udpon occasions he seems to have dis laye much magnificence. The papers of the period speak of the splendour of some of his entertainments when ambassador in Holland, and a news-letter of 1724 mentions his appearance at the drawing-room on the prince’s birthday ‘very rich in jewels.' As a soldier Cadogan must be ranked among the ablest stall' ofiicers the British army has produced. The confidence reposed in his judgment by Marlborough and the high opinions expressed of him by Prince Eugene and other foreign officers of note bespeak his high capacity; he brought energy and skill to bear upon the details of his great leader’s plans, and showed eminent administrative ability in performing the multifarious duties of a quartermaster-general.
General General Charles Cadogan, who succeeded his brother as Baron Cadogan of Oakley, entered the army in 1706, in the Coldstream guards. He served in some of Marlborough’s ater campaigns and in Scotland in 1715. He sat in several parliaments for Reading, and afterwards for Newport, Isle of Wight. He purchased the colonelcy of the 4th ‘king’s own’ foot in 1719, and in 1734 became colonel of the 6th Inniskillin dragoons. He married a daughter of Sir Hans Sloane, with which alliance commenced the connection of the Cadogan famil with the borough of Chelsea. At his dee which occurred at his residence in Bruton treet, on 24 Sept. 1776, at the age of 85 (see Foster, Peerage), Charles, lord Cadogan, was a general, colonel of the 2nd troop of hourse guards, governor of Gravesend and Tilbury Fort, a F.R.S., and a trustee of the British Museum. His only son, Charles Sloane, was created Viscount Chelsea and Earl Cadogan 27 Dec. 1800.
[Earl Cadogan’s name has not been found in the early volumes of Irish Military Entry Books in the Dublin Record Office, odd volumes of which go back to 1697. His later commissions and appointments, subsequent to 1715, appear in the some Office Military Entry Books and the Treasury and Ordnance Warrant Books, under date, in Public Record Office, London. Notices of his services occur incidentally in Lediard’s Life of Marlborough; in Coxe’s Life of Marlborough, the preface to which indicates various sources of information; in the Marlborough Despatches, edited by Sir George Murray; in the ndon Gazettes of the period; in Lettres Historiques, published at the Hague, of which there is a complete series in the British Museum ; in the published records of various regiments of cavalry and infantry which served in Marlborough’s campaigns and can be traced through the Army List; in Correspondence of Sarah, Duchess of Marlborough, 1834; and in Lord Mahon`s History of England, vol. i., where is every impartial account of the campaign in Scotland in 1715. The statements in the Stuart and Hanover papers, in Original Papers, by Macpherson, must be received with much reservation. Clode's observations on the military expenditure of the period, in Military Forces of the Crown, i. 118-24, deserve attention, and many of the military entries in the printed Calendars of Treasury Papers for the period indirectly illustrate the impecunious condition of the service at home at the time. The British Museum Cat. Printed Books, which has over 120 entries under the name of the first Duke of Marlborough, has but one under that of the first Earl Cadogan-a printed copy of a diplomatic note respecting a British vessel pillaged by the Dutch at Curacoa in 1716. Among the biographical notices of Cadogan which have appeared, mention may be made of those in Collins's Peerage, 2nd ed., v. 450, &c.; Grainger’s Biog. Hist. vol. iii. ; Timbs’s Georgian Era, vol. ii.; General Sir Frederick Hamilton’s Origin and Hist. 1st or Grenadier Gds. vol. ii. ; Cannon’s Hist. Rec. 5th Drag; Gds. A memoir which appeared in Colburn’s United Service Mag. January-April 1872, headed ‘Marlborough's Lieutenants,’ is chiefly noticeable for its numberless errors and misstatemeuts. Manuscript information is more abundant. Among the materials in the Public Records are: Foreign Oihce Records-Flanders, Nos. 132-5, correspondence from Brussels in 1709-10; ditto, Flanders, No. 146, similar correspondence in
