Bengal Native Infantry

The regiments of Bengal Native Infantry, alongside the regiments of Bengal European Infantry, were the regular infantry components of the East India Company's Bengal Army from the raising of the first Native battalion in 1757 to the passing into law of the Government of India Act 1858 (as a direct result of the Indian Mutiny). At this latter point control of the East India Company's Bengal Presidency passed to the British Government. The first locally recruited battalion was raised by the East India Company in 1757 and by the start of 1857 there were 74 regiments of Bengal Native Infantry in the Bengal Army. Following the Mutiny the Presidency armies came under the direct control of the United Kingdom Government and there was a widespread reorganisation of the Bengal Army that saw the Bengal Native Infantry regiments reduced to 45.

The title "Bengal Native Infantry" fell out of use in 1885 and the Bengal Infantry regiments ceased to exist when the three separate Presidency armies were absorbed into the British Indian Army in 1903. There are units currently serving in the armies of India, Pakistan and the United Kingdom who can trace their lineage directly to units of the Bengal Native Infantry, for example the Jat Regiment in the Indian Army, the Royal Gurkha Rifles in the British Army and 6th Battalion, The Punjab Regiment in the Army of Pakistan.

The first locally recruited unit of the East India Company's forces in Bengal, raised in 1757 and present at the Battle of Plassey, was known as the Galliez Battalion (named after one of its first Captains) and called the Lal Pultan (Red Battalion) by its locally recruited members. The Bengal Native Infantry regiments underwent frequent changes of numbering during their existence, with the numbers assigned following a reorganisation bearing little or no connection to the regiments that held the pre-existing numbers. The traditional formation of British and Presidency armies' regiments was by a hierarchy in which the "1st Regiment" was the oldest and the highest number was given to the youngest. In 1764 however, the Bengal Native Infantry regiments were renumbered in the order of the individual seniority of their commanding officers. The regiments were reorganised and renumbered (or renamed) twice in 1861, in 1864, again in 1885 and finally in 1903 the Bengal Army was absorbed into the British Indian Army and the Bengal Infantry ceased to exist.

The inclusion of the word "Native" in the titles of the Bengal Native Infantry regiments and throughout the Bengal, Bombay and Madras Armies indicated that the troops were locally recruited in India (or neighbouring areas), in contrast with the Bengal European Infantry which recruited personnel in the United Kingdom. In 1885, the word "Native" was dropped from the titles of all military units in the Bengal Army.

The 1st Brahmans was the first infantry regiment of the British Indian Army. It was raised at Oudh by Captain T Naylor in 1776

The Bengal army mostly recruited upper-caste elements like Kanyakubja Brahmins, Rajputs, from Awadh.

Bengal Native Infantry regiments typically consisted of 800 privates (sepoys), 120 non-commissioned officers (havildars and naiks), 20 native commissioned officers (subedars and jemadars), 2 British sergeants and 26 British commissioned officers. Regiments were commanded by a lieutenant-colonel and were divided into 10 companies, each assigned 2 British officers and 2 native officers. Each regiment was assigned an adjutant, an interpreter and a quartermaster. The majority of recruits for the Bengal Native Infantry in the years leading up to the Mutiny were from the districts of Bengal, Oudh (Awadh) and the surrounding areas – around three quarters of the total numbers.

Mutinying regiments officially ceased to exist following the Mutiny and in 1861 the twelve surviving Bengal Native Infantry regiments (units that did not mutiny, units that were disarmed and later considered to be free of mutineers or units that were disbanded peacefully & were later reformed) were joined by a mix of hastily raised units (for example, the Allahabad Levy became the 33rd Bengal Native Infantry) or newly created units from the Punjab (for example, the 7th Regiment of Punjab Infantry became the 19th Bengal Native Infantry). In addition, soldiers who did not mutiny when the rest of their regiment did so joined units such as The Lucknow Regiment or The Loyal Purbiah Regiment.
