The regiment consisted of four troops, three of which were originally troops in the "English Regiment of Light Horse in France" attached to the French army of Louis XIV and under the command of Sir Henry Jones. They were constituted in 1672 and, after Jones was killed during the siege of Maastricht in 1673 while serving with the Duke of Monmouth, command passed to the Duke. The regiment was ranked as the 1st Dragoons, the oldest cavalry regiment of the line, in 1674. The regiment was recalled to England in 1678 (it was disbanded in France and reformed in England with most of the same officers) with the expectation of fighting in a war against France. In early 1679, it was disbanded and then reformed in June of that year as "Gerard's Regiment of Horse" (its colonel being Charles Gerard), with most of the same officers and men, to police the Covenanters in Scotland. The regiment was disbanded in late 1679 and three of its captains, John Coy, Thomas Langston and Charles Nedby, along with their troopers, went out to Tangier in 1680 as reinforcements. When they returned in 1683, they joined what became a new permanent regiment of the Royal Dragoons.
