The Royal Dragoon Guards have a long and distinguished history dating from 1685.

Originally raised as regiments of horse and dragoons, they were subsequently designated as the 4th, 5th and 7th Dragoon Guards and the 6th (Inniskilling) Dragoons. They fought in all of Britain's major wars from the late 17th century onwards, charging at Blenheim with Marlborough's cavalry, at Waterloo with the Union Brigade, and at Balaklava with the Heavy Brigade. In the 19th century, they also saw service in India and Africa.

All four regiments served in France and Flanders during the First World War and one regiment fired the first British shot on the Western Front. They were then amalgamated into two regiments – the 4th/7th Royal Dragoon Guards and the 5th Royal Inniskilling Dragoon Guards.

Both regiments were mechanised shortly before the Second World War, in which they played a leading role in the D-Day landings. In 1992, the two regiments amalgamated again to form the Royal Dragoon Guards. Recent conflicts have taken the regiment to Iraq and Afghanistan, continuing a record of operational service covering more than three centuries.

This regimental history of the Dragoons tells their story as it played out across the centuries, exploring their role in both major and minor conflicts of the last 300 years. The title examines the development of the regiment up to the present day and highlights key figures across its history. The text is supported throughout with photographs and illustrations.
