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 six troops of the Ironsides, Lt General Oliver Cromwell’s Regiment of Horse as the General’s Regiment of the New Model Army, and accompanied Cromwell on his raid into Oxfordshire. At Naseby Fairfax notably led the regiment to break one of the last standing Royalist infantry regiments. Three troops of the regiment, together with troops of Whalley’s regiment (also previously Cromwell’s horse) distinguished themselves by playing the major part in defeating Goring’s army at Langport.

In 1647 the regiment was caught up in Army politics, and Major John Desborough was accused of attacking a detachment of Sir Robert Pye’s horse at Deptford. Trooper Edward Sexby was a notorious agitator from the regiment. In the Second Civil War Desborough led two troops to suppress a rising in Norfolk. The regiment were under Fairfax’s command at Maidstone and Colchester. With Fairfax’s resignation in 1650, Cromwell led the regiment into Scotland, where it served with distinction at Dunbar and later at Worcester.

During the restoration crisis Monck arranged for the regiment to be moved out of London and dispersed. One troop each was quartered at Reading, Gloucester, Worcester and Hereford and two at Oxford. Robert Hesilrige’s troop joined Lambert, but surrendered at Daventry with no bloodshed. After the restoration the regiment was one of the last four to be disbanded, probably in February 1661.
