7th Dragoon Guards
The 7th (The Princess Royal's) Dragoon Guards was a cavalry regiment in the British Army, first raised in 1688 as Lord Cavendish's Regiment of Horse. It was renamed as the 7th (The Princess Royal's) Dragoon Guards for Princess Charlotte in 1788. It saw service for two centuries, including the First World War, before being amalgamated with the 4th Royal Irish Dragoon Guards, to form the 4th/7th Dragoon Guards in 1922. History

During the 1688 Glorious Revolution, William Cavendish, later Duke of Devonshire, raised a troop of horse to provide an escort for Princess Anne, younger daughter of James II. After James fled into exile, a number of independent troops were brought together to form Lord Cavendish's Regiment of Horse. During the Williamite War in Ireland, it fought at the Battle of the Boyne in July 1690, before moving to Flanders in 1692 to serve in the Nine Years' War. It took part in the action at Dottignies in July 1693 and the siege of Namur in July 1695, before the war ended with the 1697 Treaty of Ryswick. Saved from disbandment by being transferred onto the Irish establishment, it served in Europe throughout the War of the Spanish Succession, fighting at Blenheim, Elixheim, Ramillies and Malplaquet. After the 1713 Treaty of Utrecht it returned to Ireland, where in 1720, French Huguenot exile and future Field Marshal John Ligonier took over as colonel, a position he held for 29 years. Under his command, the unit gained a reputation as one of the best trained and efficient units in the British army; between 1742 and 1747, 37 members of the regiment received battlefield commissions for distinguished service, a record 'without parallel for the period.' As late as 1913, recruits were still taught about Ligonier, while his personal crest and motto were borne by every member of the regiment. Sent back to Flanders in 1742 for the War of the Austrian Succession, the regiment fought in the battles of Dettingen and Fontenoy. At Lauffeld in July 1747, it took part in a famous charge led by Ligonier that allowed their infantry to escape what was an Allied defeat. After the 1748 Treaty of Aix-la-Chapelle, it returned to garrison duty in Ireland. In the army reforms of 1747, it was ranked as the 4th Regiment of Horse, or the "Black Horse". It remained in Ireland until July 1760, when it fought at Warburg, during the Seven Years' War. In 1788, it was retitled 7th (The Princess Royal's) Dragoon Guards, after Princess Charlotte. It remained in Ireland and England throughout the wars with France and helped suppress the 1798 Irish Rebellion. During the Victorian era, it was sent to South Africa in 1843, where it remained until after the 1846–1847 Xhosa War. In 1857, it was posted to India, returning home in 1867 where it remained until the 1882 Anglo-Egyptian War. Following the outbreak of the Second Boer War in late 1899, the regiment was again sent abroad for service in South Africa. A total of 24 officers and 500 men left Southampton in the SS Armenian on 8 February 1900. The regiment fought at the Battle of Diamond Hill in June 1900. The regiment, which had been serving in Secunderabad at the start of the First World War, landed in Marseille as part of the 9th (Secunderabad) Cavalry Brigade in the 1st Indian Cavalry Division in October 1914 for service on the Western Front. A squadron from the regiment rode ten miles to capture the town of Lessines on 11 November 1918 shortly before the armistice. It was re-titled as the 7th Dragoon Guards (Princess Royal's) in 1921, and was amalgamated with the 4th Royal Irish Dragoon Guards, to form the 4th/7th Dragoon Guards in 1922. Regimental museum
