JOHN CAMPBELL, 2nd duke of Argyll and duke of Greenwich (1678-1743), son of the preceding, was born Oct. Io 1678. In return for his services in promoting the Union, he was created (1705) a peer of England, with the titles of baron of Chatham and earl of Greenwich. He served at the battle of Oudenarde (1708) and at the sieges of Lille, Ghent, Bruges and Tournay, doing remarkable service at the battle of Malplaquet in 17o9. He was very popular with the troops, and his rivalry with Marl borough on this account may have been the cause of their later enmity. In 1711 he was sent to take command in Spain ; but being seized with a violent fever at Barcelona, and disappointed of supplies from home, he returned to England. In the House of Lords he censured the measures of the ministry with such freedom that all his places were disposed of to other noblemen; but at the accession of George I. he recovered his influence. In the rebellion of 1715 he was appointed commander-in-chief of the forces in north Britain, and effected the total extinction of the rebellion in Scotland without much bloodshed. He arrived in London early in March 1716, and at first stood high in the favour of the King, but in a few months was stripped of his offices. He supported the bill for the impeachment of Bishop Atterbury, and opposed the bill for punishing the city of Edin burgh for the Porteous riot. In the beginning of the year I 7 rq he was again admitted into favour, created Duke of Greenwich; he held various offices in succession, and in 1735 was made a field marshal. He continued in the administration till after the acces sion of George II., when, in April 1740, a violent speech against the government led again to his dismissal from office. Restored on a change of the ministry, but disapproving the measures of the new administration, he shortly resigned all his posts, and spent the rest of his life in retirement. He died Oct. 4 1743. A monument by Roubillac was erected to his memory in West minster Abbey.
