DALYELL (or DALZIELL or DALZELL), THOMAS (d. 1685), British soldier, was the son of Thomas Dalyell of Binns, Linlith gowshire. He was present at the battle of Worcester (Sept. 3, 1651), when. his men surrendered, and he himself was captured and imprisoned in the Tower. In May he escaped abroad, and in 1654 took part in the Highland rebellion and was excepted from Cromwell's act of grace, a reward of L200 being offered for his cap ture, dead or alive. The king's cause being now for the time hope less, Dalyell entered the service of the tsar of Russia, and fought in the wars against the Turks and Tatars. He returned to Charles in 1665, and on July 19, 1666, he was appointed commander-in chief in Scotland to subdue the Covenanters. He defeated them at Rullion Green and exercised his powers with great cruelty, his name becoming a terror to the peasants. He obtained several of the forfeited estates. On Jan. 3, 1667, he was made a privy coun cillor, and from 1678 till his death represented Linlithgow in the Scottish parliament. He was incensed by the choice of the duke of Monmouth as commander-in-chief in June 1679, and was con firmed in his original appointment by Charles, but in consequence did not appear at Bothwell Bridge till after the close of the engage ment. On Nov. 25, 1681, a commission was issued authorizing him to enrol the regiment afterwards known as the Scots Greys. He was continued in his appointment by James II., but died soon after the latter's accession in Aug. 1685.
