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 Sir Arthur Hesilrigge’s Regiment of Horse of Waller’s army. At Naseby it was broken by the charge of Rupert’s wing, but went on to do good service in Fairfax’s western campaign.

In the Second Civil War Horton led a small force to South Wales, and the regiment were distinguished in his defeat of Laugharne’s larger force at the Battle of St. Fagan’s. They were then joined by Cromwell and participated in the sieges of Tenby and Pembroke. In 1649 the regiment were ordered to Ireland, sailing from Milford Haven. Horton soon died from a fever and was replaced by Jerome Sankey (or Zanchy).

During Booth’s rising of 1659 Sankey returned to England with the ‘Irish Brigade’ of 1000 foot and 500 horse, but arrived too late for Winnington Bridge, accepting the surrender of Chirk Castle instead. During the Restoration crisis Sankey marched the brigade to London, then to the North in support of Lambert, where in December they changed sides to Monck. Sankey was dismissed and the brigade put under the command of Colonel Redman.

Flags and Equipment

Were equipped as harquebusiers, not cuirassiers, in contrast to their earlier career as Hesilrigge's 'London Lobsters'.

Notable Officers

Lists of officers for April and May 1645, December 1646, May and August 1647 and May 1649 are shown in Reconstructing the New Model Army. Volume 1, Regimental Lists April 1645 to May 1649 by Malcolm Wanklyn, Helion & Co. 2015. ISBN 978-1-910777-10-7.

Colonel John Butler

Captain and later Major of Sir Arthur Hesilrigge’s regiment of horse, he was appointed Colonel to take the regiment into the New Model Army after Lt Gen John Middleton declined the position. In 1647 Butler supported Parliament over the Army and in June he left the Army.

Colonel Thomas Horton

Thomas Horton (1603-1649) served in Hessilrigge's Regiment of horse, then as Major under Butler, replacing him as Colonel in 1647. He comprehensively defeated the South Wales Royalists in 1648, then took the regiment to Ireland where he died ‘of the country disease’ according to Cromwell, in October 1649.

Colonel Jerome Sankey

Jerome Sankey (d 1687) (or, variously Hierome Zanchey) originally from Shropshire was educated at Cambridge but excelled mainly in cudgelling and foot-ball-playing. He served in Sir William Brereton’s regiment of horse, leading the Colonel’s troop in 1645. Replacing Horton in Ireland he captured the renegade Colonel Edward Wogan near Cork and was later governor of Clonmel where he was accused of various cruelties. He returned to England in 1659 and supported Lambert, but was removed from command by Monck. He quarrelled with Sir William Petty in 1659 and, on challenging the notoriously short-sighted Petty to a duel, was accepted with the conditions stipulated being a dark cellar and both parties armed with a carpenter’s axe. The situation was considered so ridiculous that the matter came to nought.
