In the _Mermaid_, under Brevet Major Ainslie. In the _Marion_, under Lieutenant-Colonel Law. In the _Ursula_, under Captain Lloyd. In the _Zion’s Hope_, under Major Swinburne. On the 8th May, 1849, the head-quarters arrived in Bombay, and on the 10th, disembarked and proceeded to Poona, and arrived at that station on the 18th of the same month. The whole of the regiment, however, was not assembled at Poona till the 14th July, 1849, where it remained till November, 1850. During the stay of the regiment at Poona, it lost by disease two officers (Captain the Hon. W. Gage and Surgeon Ledingham), 5 sergeants, 1 drummer, and 69 rank and file. [Sidenote: 1850.] In November, 1850, the regiment marched in four divisions on the 2nd, 3rd, 4th, and 11th of the month for Panwell and Bombay, and embarked in steamers for Kurrachee, where the head-quarters arrived and disembarked on the 14th of the same month, but the last division did not join the regiment till the 1st December following. [Sidenote: 1851.] In January, 1851, Lieutenant-Colonel Trydell was appointed to the command of the Poona brigade, and Lieutenant-Colonel W. H. Law assumed command of the regiment. From November, 1850, to 31st December, 1852, the regiment was stationed at Kurrachee, and lost through disease during that period 5 officers--viz., Major Townsend, Lieutenant and Adjutant W. Hall,[16] Ensign Graham, Quartermaster Colburn (at Poona when on leave), and Assistant-Surgeon Boyce--and 6 sergeants, 3 drummers, and 135 rank and file, chiefly cases of cholera, fever, and dysentery. On two occasions--viz., in May and June, 1851, and again in September and October, 1852--the regiment was visited with cholera, fever, and dysentery, and suffered greatly, and on the last occasion it was considered necessary to remove the regiment from the barracks and encamp the men on Ghizree Heights, near the sea.[17] [Sidenote: 1852.] It, however, soon recovered from these fell diseases, and numbered upwards of 950 efficient soldiers, men strong and stalwart in form, perfect in discipline, and influenced in no ordinary degree by an ardent _esprit de corps_, the prestige of the honourable name and high reputation won by the 83rd wherever it served. [Sidenote: 1853.] On the 8th February, the right wing of the regiment (448 strength), under the command of Brevet Lieutenant-Colonel Swinburne, proceeded in river steamers by the Indus River to Hyderabad, there to be stationed. On the 15th March, 1853, the establishment of the regiment was altered by Horse Guards’ letter, dated 24th March, 1853, to 12 captains, 20 lieutenants, 4 ensigns, and 1 adjutant.
