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.

Ingoldsby’s regiment was formed from his own Regiment of Foot and probably drafts from other regiments of Essex’s army. They missed Naseby, serving instead at Taunton, on Fairfax’s Western campaign and at the siege of Oxford. After Oxford surrendered they were installed as garrison of the City.

In 1647 the regiment were ordered to disband but refused, by this time their arrears had arrived at Oxford and they refused to return them. For the next two years they enforced the ‘Visitation and Reformation’ of Oxford University; this involved imprisoning recalcitrant heads of colleges and college officers and suppressing disorders amongst the scholars. During the Second Civil War a detachment of the regiment assisted Fairfax at the siege of Colchester.

1651 saw the regiment sent to Scotland under Cromwell’s command and fighting at the Battle of Worcester. From 1652 detachments from the regiments served as marines in the First Anglo-Dutch War, while the main part of the regiment was quartered in London. After a succession of Colonels in the late 1650s they were disbanded in November 1660.

Coats, Flags and Equipment

Red coats. Their flag colours and designs are unknown but it's possible that they continued with the standards they'd been issued as Tyrell’s regiment in November 1644. These were either green colours (with differences of yellow billets, yellow half-moons or white diamonds), or crimson colours (with differences of yellow mullets or white balls).

Notable Officers

Colonel Richard Ingoldsby

Richard Ingoldsby A regicide and loyal Cromwellian, he sat as an MP in the First and Second Protectorate parliaments and was styled “Lord Ingoldsby” in Cromwell's “Other House”. As the Restoration became increasingly likely, however, Ingoldsby looked for ways to demonstrate support for Charles II. In April 1660, Monck sent him in pursuit of Lambert, who was attempting to rally military resistance to the Restoration. Ingoldsby captured Lambert at a skirmish near Daventry. He was pardoned for his role as a regicide after claiming that Cromwell had forced him to sign Charles I's death warrant by seizing his hand and tracing out his signature. Uniquely among the regicides, Ingoldsby was allowed to retain all the lands he had acquired during the Protectorate, was made a Knight of the Bath and appointed a gentleman of Charles II's privy chamber.

Colonel John Mill

Captain in the regiment in 1645 he was acting Lt Col by 1651, then made permanent. In 1655 he was given command on the departure of Ingoldsby, as a reliable supporter of the Protectorate but was replaced by Sydenham on the fall of Richard Cromwell.

Colonel William Sydenham

Sir John Lenthall

Earl of Northampton
