​CATHCART, WILLIAM SCHAW CATHCART, 1st Earl (1755–1843), English soldier and diplomatist, was born at Petersham on the 17th of September 1755, and educated at Eton. In 1771 he went to St Petersburg, where his father, Charles, 9th Baron Cathcart (1721–1776), a general in the army, was ambassador. From 1773 to 1777 he studied law, but after succeeding to the barony in 1776 he obtained a commission in the cavalry. Proceeding to America in 1777, he had before the close of his first campaign twice won promotion on the field of battle. In 1778 he further distinguished himself in outpost work, and at the battle of Monmouth he commanded an irregular corps, the “British Legion,” with conspicuous success; for a time also he acted as quartermaster-general to the forces in America. He returned home in 1780, and in February 1781 was made captain and lieutenant-colonel in the Coldstream Guards. He was elected a representative peer for Scotland in 1788, and in 1792 he became colonel of the 29th foot. He served with distinction in the campaigns in the Low Countries, 1793–1795, in the course of which he was promoted major-general; and in 1801 he was made a lieutenant-general, having in the meanwhile received the appointments of vice-admiral of Scotland (1795), privy councillor (1798), and colonel of the 2nd Life Guards (1797). From 1803 to 1805 Lord Cathcart was commander-in-chief in Ireland, and in the latter year he was sent by Pitt in command of the British expedition to Hanover (see Napoleonic Campaigns). After the recall of this expedition Cathcart commanded the forces in Scotland until 1807, when he was placed in charge of the expedition to Copenhagen, which surrendered to him on the 6th of September. Four weeks later he was created Viscount Cathcart of Cathcart and Baron Greenock of Greenock in the peerage of the United Kingdom, resuming the Scottish command on his return from the front. On the 1st of January 1812 he was promoted to the full rank of general, and a few months later he proceeded to Russia as ambassador and military commissioner. In the latter capacity he served with the headquarters of the allies throughout the War of Liberation (1812–1814); his success in the delicate and difficult task of maintaining harmony and devotion to the common cause amongst the generals of many nationalities was recognized after the war by his elevation to the earldom (July 1814). He then went to St Petersburg, and continued to hold the post of ambassador until 1820, when he returned to England. He died at his estate near Glasgow on the 16th of June 1843.
His son, Charles Murray Cathcart, 2nd earl (1783–1859), succeeded to the title in 1843. He entered the 2nd Life Guards in 1800, and saw active service under Sir James Craig in the Mediterranean, 1805–1806. In 1807 he became by courtesy Lord Greenock. He took part in the Walcheren expedition of 1809 as a major, and as a lieutenant-colonel served at Barossa, Salamanca and Vittoria. He had already gained staff experience, and he now served under Graham in Holland, 1814, as quartermaster-general. He was present at Waterloo, and for his services received the C.B. and several foreign orders. During the peace he became deeply interested in scientific pursuits, and a new mineral discovered by him in 1841 was named Greenockite. His later military services included the chief command in Canada during a period of grave unrest (1846–1849). He retired from active service in 1850, becoming a full general just before his death. The title passed to his son and grandson as 3rd and 4th earls.
