The 18th Royal Hussars (Queen Mary's Own) was a cavalry regiment of the British Army, first formed in 1759.

[6] The regiment was ordered to support Sir Arthur Wellesley's Army on the Iberian Peninsula and landed at Lisbon in February 1813.

[15] It then remained in France as part of the Army of Occupation brigaded with the 12th (Prince of Wales's) Regiment of (Light) Dragoons under the overall command of Major-General Sir Hussey Vivian.

At the outbreak of hostilities on 11 October 1899 it was one of only two regular cavalry regiments in South Africa.

In the Battle of Talana Hill, on 20 October, part of the regiment was cut off by Boer forces and about 249 officers and men, including Lieutenant Colonel Benhardt Moller, were taken prisoner.

In 1878 the green facings were replaced by blue bags and white plumes which had distinguished the original 18th Hussars.

The horse furniture of officers included red and white throat plumes and leopardskins under the saddle.
