Haynes supported the parliamentary cause during the
English Civil War. At the outbreak of war he took a captains commission in Colonel
Holborne's regiment of foot. He transferred to
Charles Fleetwood's cavalry regiment and by 1645 had risen to the rank of major. He fought at
Battle of Preston in 1648, commanded the regiment at the
Battle of Dunbar in 1650 and may well have
fought at Worcester in the last battle of the Civil War. After the death of
Oliver Cromwell, Haynes supported the
Wallingford House party when they overthrew
Richard Cromwell and in 1659 introduced the short lived second Commonwealth. In December, shortly before the Restoration, the
Rump Parliament ordered him to leave London and return home, but he chose not to. In November 1660 he was arrested on suspicion of subversion, and held in the
Tower of London for 18 months. He was released in April 1662 upon payment of a £5,000 bond for his future good behaviour. He retired to his family estate of
Copford Hall and lived quietly until his death on 26 August 1693.
Family Haynes was the second son of
John Haynes of Copford Hall in
Essex and Mary Thornton, daughter of Robert Thornton of Nottingham. In the early 1650s he married Anne, daughter of Thomas Smithsby, the former saddler to Charles I. They had at least one son. Haynes passed the family seat of Copford Hall over to his son in 1684, and moved to
Coggeshall where he died in 1693. == Notes ==
