After serving with distinction in the low countries, Lord Fairfax was declared general-in-chief of the parliament army at the opening of the civil war, in 1642, and again in 1645. Fairfax distinguished himself in most of the great battles and sieges of that struggle, and after its close refused to act as one of the judges of Charles I. In 1659, Lord Fairfax used all his influence with the army to promote the restoration of Charles II. Died 1671.
