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

Lockhart’s regiment was raised in London and Berkshire for service in the garrison of Dunkirk. Advertisements enjoined volunteers to sign up at the Boreshead in Kingstreet Westminster, Captain Brett’s house at the Tower of London, the Bell Inn, Kingstreet Westminster and the Pelican at Speenhamland in Newbury. In 1658 they arrived in Flanders where they garrisoned Dunkirk and participated in skirmishes and cattle-raids.

In 1660 Sir Edward Harley replaced Lockhart as Colonel, and he soon passed the regiment to his brother, Robert. By 1661 Robert was no longer Colonel but the regiment were still in garrison at Dunkirk, the city being governed by Lord Rutherford. In 1662 three troops were sent to join the Portugal expedition and in November the remainder of the regiment was disbanded at Dunkirk.
