He was promoted to the rank of Colonel in 1780, and in 1782 he obtained the Colonelcy of the Seventy-fifth, or the Prince of Wales's Regiment of Foot, which was disbanded at the termination of the American war, in 1783. In 1785 he obtained the Colonelcy of the SEVENTEENTH Light Dragoons; in 1787 he was promoted to the rank of Major-General, and he succeeded to the dignity of DUKE OF NEWCASTLE on the decease of his father, in 1794. He died in 1795. OLIVER DE LANCEY, _Appointed 20th May, 1795_. OLIVER DE LANCEY descended from a respectable family settled in North America. When a disposition to make themselves independent appeared in the Colonies, he wrote a pamphlet entitled, "Considerations on the Propriety of Imposing Taxes on the British Colonies," which was first printed in America, and afterwards went through the press several times in London. Proceeding to Great Britain, he procured the commission of Cornet in the Fourteenth Dragoons, in 1766, and in May, 1773, he was appointed Captain in the SEVENTEENTH Light Dragoons, in which corps he remained forty-nine years.

He commanded a squadron of the SEVENTEENTH on Long Island, distinguished himself in the driving back of the American piquets, and also at the battle of Brooklyn. Crossing the river to New York he had further opportunities of signalizing himself, and in the spring of 1777 he served in the Jerseys, where the squadron under his orders had several rencounters with detachments of the enemy.
