A history of the regiment is given in The Regimental History of Cromwell's Army by Sir Charles Firth and Godfrey Davies, Clarendon Press, Oxford, 1940.

The regiment was formed from James Sheffield’s Regiment of Horse. At first command was to be given to James, but the Colonelcy went to his brother Thomas. Sheffield’s regiment fought at Naseby and a succession of sieges in the West, then at the siege of Oxford.

In 1647 the regiment refused to go to Ireland and Sheffield was replaced by Harrison, who had served in Fleetwood’s regiment. At the start of the Second Civil War the regiment joined Lambert’s force in the North, fighting at Preston. The next year two troops joined the Leveller mutiny and the regiment were later sent to garrison South Wales. In 1651 they formed part of Harrison’s force in Lancashire and took part in the Battle of Worcester.

The regiment were sent to Scotland in 1654, helping to put down Glencairn’s rising in 1654. Harrison was dismissed after opposing Cromwell and the regiment given to Stephen Winthrop, then Edward Montagu. During the Restoration crisis Montagu was replaced by Alured and two troops joined with Lambert and were captured at Daventry. In November 1660 they were disbanded in Shropshire.

Flags and Equipment

Carried red cornets under Sheffield

According to Blount: Col. Thomas Sheffield (second Son to the Earl of Mulgrave) bore this motto only without figure, NEC TIMIDUS, NEC TUMIDUS2).

Major William Rainsborough's cornet (Illustration 1) under Col. Harrison, was blue depicting the beheading of Charles I with the motto salus populi: suprema lex (let the good of the people be the supreme law).

Notable Officers

Colonel Thomas Sheffield

A younger son of Edmund, Lord Sheffield, Earl of Mulgrave, he served as Captain in his brother James’ regiment of horse in Essex’s army and was appointed Colonel when the regiment was New Modelled. Sheffield supported Parliament rather than the army in 1647 and so lost his command.

Colonel Thomas Harrison

William Rainsborough

William Rainsborough brother of the Leveller Thomas Rainsborough, he served as a captain under Sheffield then Major under Harrison. As a Fifth Monarchist he was dismissed for his extreme views in 1649.

Colonel Stephen Winthrop

Colonel Edward Montagu

Colonel Matthew Alured

Colonel of a Regiment of Horse in the Fairfaxes’ army of the First Civil War.

Trooper Samuel Pepys

Samuel Pepys the famous diarist, was due the pay of a trooper when the regiment disbanded. Although he claimed to have been secretary to the Colonel (Montagu rather than Alured), likely this was a sinecure.
