The regiment was founded as two irregular cavalry regiments in 1857, at the outset of the Indian Rebellion of 1857 by Henry Otway Mayne, and was known initially as Mayne's Horse and the 2nd regiment which was known as Beatson's Horse. They were based at the town of Guna, in the state of Gwalior and Augar in central India. In 1860 Mayne's Horse was renamed the 1st Regiment Central India Horse, and Beatson's Horse was renamed the 2nd Regiment Central India Horse. In 1860 the officer commanding the Central India Horse was made the British political officer for the small states of Raghugarh, Khaniadhana, Paron, Garha, Umri, and Bhadaura, which were made a separate charge from that of the Resident of Gwalior. This arrangement was abolished in 1896, when these states were again placed under the resident, with the officer commanding at Guna continuing to act as ex-officio assistant to the Resident, with very limited powers. Both Regiments would serve together in the Second Afghan War.
Reorganisation
During the Kitchener reorganisation of the Indian Army of 1903, the 1st Regiment became the 38th Regiment Central India Horse, and the 2nd regiment became the 39th Regiment Central India Horse. In 1906, the regiments were renamed the 38th and 39th Prince of Wales's Own Central India Horse, and in 1910 the 38th and 39th King George's Own Central India Horse.
In 1921, the two regiments were amalgamated into the 38th/39th Cavalry, which was renamed the 38th/39th King George's Own Light Cavalry, The Central India Horse , and The Central India Horse .
During the Second World War, the Central India Horse was the divisional reconnaissance regiment for the 4th Indian Division. While attached to the 4th Indian Division they were involved in the Western Desert Campaign, the East African Campaign, the Tunisia Campaign and the Italian Campaign. It was during the Italian Campaign that two members of the Regiment were posthumously awarded the George Cross: Ditto Ram and St. John Graham Young attached from the Royal Tank Regiment. Notice of the award was published in the London Gazette on 20 July 1945. Young had been leading a night patrol on 23 July 1944, when he and his men found themselves in any enemy minefield. He received the full force of a mine explosion, severely injuring both legs. Despite his wounds, his encouragement enabled the majority of his men to reach safety. One of them, Sowar Ditto Ram, was also posthumously awarded the GC for his actions in the same incident.
Bombay 'mutiny'
In 1940, the Central India Horse was posted to Egypt. While awaiting embarkation the train carrying the regiment was kept in a siding for about twenty-four hours. During this delay four members of a radical political organization – the Kirti Lehar were able to persuade two-thirds of the Sikh squadron of the regiment to refuse overseas service. The remainder of the regiment embarked for North Africa and Italy where it served with distinction. The 'mutineers' were court-martialed.
On March 20, 1942 Captain Arthur Sandeman of the Central India Horse was on secondment to the Burma Frontier Force - leading a mounted infantry column. Near Toungoo airfield in central Burma the 60-man mounted patrol mistook Japanese troops for Chinese ones and closed with them before realizing their mistake. Most of the patrol were killed in what was probably the last cavalry charge by a force under the command of the British crown. Also Hon Capt Ram Bhaj was awarded IOM IDSM during the Second World War.
Independence
Upon India's independence, the Central India Horse was allocated to India, although a Muslim Punjabi squadron was transferred to the 19th King George V's Own Lancers in exchange for its Jat squadron. When India became a republic in 1950, the regiment was renamed The Central India Horse, which is one of the decorated regiments of the Indian Army. The Central India Horse is now a tank regiment of the Indian Army's XXI Corps.
