The greater number of them had belonged to the Company’s 1st and 3rd Bengal Native Cavalry.
In September, General William Pattle C.B. was gazetted to be Colonel of the regiment. He was an old Company’s officer who had entered the service in 1800. He served under Lord Lake in the Mahratta campaigns of 1803 and 1804, and was present at the battles of Alyghur, Delhi, Laswaree, the siege of Bhurtpore &c. He served through the Mahratta war of 1817–18, and commanded the cavalry under Sir Charles Napier, during the conquest of Scinde, and at the battles of Meeanee and Hyderabad.
Under orders from the War office, dated 6th January 1863, the establishment was reduced by one troop, leaving seven service troops and one at Maidstone.
In the autumn, orders were received for the regiment to march to Meerut, where it arrived 28th November. Here the regiment remained till the end of 1867. The only events to be noticed during these four years are a reduction of establishment by 56 privates in 1866: and the presence of the regiment at the great Durbar held by the Viceroy, Sir John Lawrence, at Agra, in November 1866, when the 19th were brigaded with the 2nd Dragoon Guards.
In the beginning of 1865, the regiment lost its Colonel by death. In his place Lieutenant General John Hall was appointed Colonel.
On the 10th December 1867, the Head Quarters of the regiment, with four troops, marched for Benares, being followed, a month later, by the remaining three troops, who marched to Cawnpore.
In the ordinary course of relief, the regiment was intended to leave India in 1872. In a sudden fit of economy, the Indian Government decided to get rid of two cavalry regiments, so that, without any previous warning, the regiment received telegraphic orders, on 18th January 1870, to proceed to England immediately. Similar orders were sent to the 7th Hussars, then serving in India. Volunteering was at once opened to men electing to serve in other regiments remaining in India, and, on 24th January, the regiment was re-united at Allahabad, whence it proceeded to Bombay, where it embarked on board the Jumna on the 14th February. So unexpected had been the move, that a draft for the regiment, from England, joined it four days before sailing. The strength of the regiment leaving India, was as follows: 18 officers, 51 sergeants and corporals, 7 trumpeters, 257 privates, 28 women and 55 children.
On the 22nd March, the regiment landed at Dover, and proceeded to Canterbury, whence all the Cavalry Depot troops, excepting those of the 20th and 21st Hussars, had been moved to Maidstone. But the British Government were as unwilling to have the home military establishment increased by the two regiments thus sent from India, as the Indian Government had been to retain them, and the idea of disbanding two regiments was entertained. The Manchester school was predominant; shortsighted financial considerations alone had any weight. The changes rung in the establishment of the regiment for the next four months show the hesitating counsels that prevailed. On the 1st April, one troop was absorbed. A month later, the establishment was nominally fixed at 25 officers, 457 Sergeants and privates, and 300 horses, but recruiting to make the regiment up to that strength was forbidden. At the end of June the establishment of horses was reduced to 200. A week later, the war between France and Germany broke out, while the question of the strength of military establishments was still being bandied about between the Treasury and the War Office. On the 1st August, orders were received to complete the strength of the regiment up to 540 of all ranks, which was done by the end of September. The number of horses was also raised to 350.
Consequent on the increase of establishment, an eighth troop was formed in February 1871.
