DEANE, RICHARD (1610-1653), British general-at-sea, major-general and regicide, was a younger son of Edward Deane of Temple Guiting or Guyting in Gloucestershire, where he was baptized July 8, 1610. In 1644 he held a command in the artillery under Essex in Cornwall and took part in the surrender after Lost withiel. Appointed comptroller of the ordnance, he commanded the artillery at Naseby and during Fairfax's campaign in the west of England in 1645. In May of that year Deane was appointed lieutenant of artillery to Cromwell in Ireland. Cromwell refused thus to be put out of the way, and Deane followed his example. He commanded Cromwell's right wing at Preston (Aug. 17-19, 1648). He was one of the commissioners for the trial of Charles I. and a member of the committee which examined the witnesses. He signed the death warrant.
In 1649 the office of lord high admiral was put into commis sion. The first commissioners were Edward Popham, Robert Blake and Deane, with the title of generals-at-sea. At the outset of the battle off the North Foreland (June 1-3, 1653) Deane was killed. He was buried in Henry VII.'s chapel at Westminster Abbey, to be disinterred at the Restoration.
