In 1646 the regiment included Captain John Fergusson's troop equipped as dragoons. In 1647 Leslie's Lifeguard troop survived to enter the Scots New Model Army, as did Lieutenant Colonel Thomas Craig's troop. The dragoon troop also continued despite not being originally part of the establishment, authorised in February 1647. In 1648, with the engagers in the ascendant, Leslie's Lifeguard troop was added to Leven's Lifeguard and a new troop to form the Duke of Hamilton's regiment of horse, riding to defeat at Preston. Raised again as three troops in 1649, they served until final defeat at the Battle of Worcester.
