The lancer regiments of Napoleon’s Army had shown how effective cavalry regiments armed with the lance could be. In 1816 an order was published directing that the 9th Light Dragoons should be armed with the lance. In 1830 the 9th provided the escorts for King William IV on his accession. On the 22nd July the Regiment was reviewed by the King and the next day he directed that they should assume the title of the “9th Queen’s Royal Lancers”. The monogram of his Royal Consort, Queen Adelaide, still forms part of the current Regiment’s insignia.
In 1842 the 9th were sent to India and in 1843 they took part in the campaign against the Mahratta State of Gwalior. They were awarded the honour ‘Punniar’ and the men present at the battle received bronze stars made from the metal of the captured Mahratta guns. In 1845 the 9th were again on active service. They took part in the final action of the first Punjab War against the Sikhs, receiving the honour ‘Sabraon’. In 1848 war again broke out against the Sikhs. At the Battle of Goojerat on the 21st February 1849, the 9th executed a very successful charge against a large body of the Sikh cavalry, capturing two standards.
For their services in the second Punjab War the 9th received the honours ‘Punjab 1848-9’, ‘Chillianwallah’, and ‘Goojerat’.
The Regiment was in India at the outbreak of the Mutiny in 1857. The 9th was the only regiment to be present at the three major actions of the campaign, the Siege of Delhi and the Relief and Siege of Lucknow, and was awarded no less than thirteen Victoria Crosses, justifying the unique honour of a salute of twenty-one guns on their departure from India. But perhaps the greatest tribute paid to the 9th was the title ‘The Delhi Spearmen’ bestowed on them by the mutineers who had reason to fear those terrible horsemen who were described by a comrade in arms as “the beau ideal of how all the British Cavalry ought to be in Oriental countries”. For their services in the Mutiny the 9th received the honours ‘Delhi 1857’, and ‘Lucknow’.
