The Indian Army during British rule, also referred to as the British Indian Army, was the main military force of India until national independence in 1947. Formed in 1895 by uniting the three Presidency armies, it was responsible for the defence of both the British Raj and the princely states, which could also have their own armies. As stated in The Imperial Gazetteer of India, the "British Government has undertaken to protect the dominions of the Native princes from invasion and even from rebellion within: its army is organized for the defence not merely of British India, but of all possessions under the suzerainty of the King-Emperor." The Indian Army was a vital part of the British Empire's military forces, especially in World War I and World War II.
The Indian Presidency armies were originally under East India Company command, and comprised the Bengal Army, Madras Army, and Bombay Army. After the Indian Rebellion of 1857, all company troops were transferred to the British Crown. In 1879, the Presidency armies were integrated into a system of four Commands with a central Commander-in-Chief. On 1 April 1895, the Presidency armies were dissolved and unified into a single Indian Army, also divided into four Commands, and the term "Indian Army" was officially used by 1903. The Commands were later replaced by two "Armies" in 1908—the Northern and Southern Army—but the Command system was restored in 1920.
About 1.5 million Indian soldiers served during the First World War. The Indian Expeditionary Forces deployed to France, Belgium, east Africa, Iraq, Egypt, and the Gallipoli peninsula, among other regions. Eleven Indian soldiers won the Victoria Cross in the war. During the Second World War some 2.5 million soldiers served, and the Indian Army became the largest volunteer army in history to that point. India itself also served as a key logistical base for Allied operations in World War II.
The force is also sometimes referred to as the Army of the Indian Empire, or Imperial Indian Army. The Indian Army should not be confused with the Army of India, which was the Indian Army plus the British Army in India (British units sent to India). With the partition of India and Pakistan into two new Dominions on 15 August 1947, the army was reconstituted and divided between the newly independent countries, with the process overseen by the last Commander-in-Chief, India, Field Marshal Sir Claude Auchinleck. Independent India would, however, retain "much of the organizing framework" of the army.
History
The Indian Army has its origins in the years after the Indian Rebellion of 1857, often called the Indian Mutiny in British histories, when in 1858 the Crown took over direct rule of British India from the East India Company. Before 1858, the precursor units of the Indian Army were units controlled by the Company and were paid for by their profits. These operated alongside units of the British Army, funded by the British government in London.
The three Presidency armies remained separate forces, each with its own Commander-in-Chief. Overall operational control was exercised by the Commander-in-Chief of the Bengal Army, who was formally the Commander-in-Chief of the East Indies. From 1861, most of the officer manpower was pooled in the three Presidential Staff Corps. After the Second Afghan War a Commission of Enquiry recommended the abolition of the presidency armies. The Ordnance, Supply and Transport, and Pay branches were by then unified.
The Punjab Frontier Force was under the direct control of the Lieutenant-Governor of the Punjab during peacetime until 1886, when it came under the Commander-in-Chief, India. The Hyderabad Contingent and other local corps remained under direct governmental control. Standing higher formations—divisions and brigades—were abandoned in 1889. No divisional staffs were maintained in peacetime, and troops were dispersed throughout the sub-continent, with internal security as their main function. In 1891 the three staff corps were merged into one Indian Staff Corps.
Two years later the Madras and Bombay armies lost their posts of Commander-in-Chief. In 1895, the Presidency Armies were abolished and the Indian Army created thereby was grouped into four commands: Bengal, Madras (including Burma), Bombay (including Sind, Quetta, and Aden), and the Punjab (including the North-West Frontier and the Punjab Frontier Force). Each was under the command of a lieutenant general, who answered directly to the C-in-C, India.
The Presidency armies were abolished with effect from 1 April 1895 by a notification of the Government of India through Army Department Order Number 981 dated 26 October 1894, unifying the three Presidency armies into a single Indian Army. The armies were amalgamated into four commands, Northern, Southern, Eastern, and Western. The Indian Army, like the Presidency armies, continued to provide armed support to the civil authorities, both in combating banditry and in case of riots and rebellion. One of the first external operations the new unified army faced was the 1899 to 1901 Boxer Rebellion in China. The 1st, 4th, and 14th Sikhs; 3rd Madras Native Infantry, 4th Goorkas, 22nd and 30th Bombay Native Infantry, 24th Punjab Infantry, 1st Madras Pioneers, No. 2 Company Bombay Sappers, No. 3 Company Madras Sappers, No. 4 Company Bengal Sappers, and the 1st Bengal Lancers, among other Indian units, all served during the Rebellion. Numerous Indian soldiers earned the China War Medal 1900 with the "Relief of Pekin" clasp for contributing to the relief of Peking and the International Legations from 10 June to 14 August 1900.
Kitchener reforms
The Kitchener reforms began in 1903 when Lord Kitchener of Khartoum, newly appointed Commander-in-Chief, India, completed the unification of the three former Presidency armies, and also the Punjab Frontier Force, the Hyderabad Contingent and other local forces, into one Indian Army.
The principles underlying the reforms were that the defence of the North-West Frontier against foreign aggression was the army's primary role and that all units were to have training and experience in that role on that frontier. Furthermore, the army's organisation should be the same in peace as in war, and maintaining internal security was for the army a secondary role, in support of the Indian Imperial Police.
Lord Kitchener found the army scattered across the country in stations at brigade or regimental strength, and in effect, providing garrisons for most of the major cities. The reformed Indian Army was to be stationed in operational formations and concentrated in the north of the subcontinent. The Commander-in-Chief's plan called for nine fighting divisions grouped in two corps commands on the main axes through the North-West Frontier. Five divisions were to be grouped on the Lucknow–Peshawar–Khyber axis, and four divisions on the Bombay–Mhow–Quetta axis. However, the cost of abandoning some thirty-four stations and building new ones in the proposed corps areas was considered prohibitive, and that aspect of the plan had to be modified.
Under the compromise adopted in 1905, the four existing commands were reduced to three, and together with Army Headquarters, arranged in ten standing divisions and four independent brigades. The commands comprised: Northern Command, which consisted of the 1st (Peshawar) Division, the 2nd (Rawalpindi) Division, the 3rd (Lahore) Division, the Kohat Brigade, the Bannu Brigade, and the Derajat Brigade; Western Command, which consisted of the 4th (Quetta) Division, the 5th (Mhow) Division, the 6th (Poona) Division, and the Aden Brigade, located in Aden in the Arabian Peninsula; and Eastern Command, which consisted of the 7th (Meerut) Division and the 8th (Lucknow) Division.
Army Headquarters retained the 9th (Secunderabad) Division and the Burma Division under its direct control. The numbered divisions were organised so that on mobilisation they could deploy a complete infantry division, a cavalry brigade, and a number of troops for internal security or local frontier defence. Permanent divisional commands were formed with an establishment of staff officers under a major general.
After the reforms ended in 1909, the Indian Army was organised along British lines, although it was always behind in terms of equipment. An Indian Army division consisted of three brigades each of four battalions. Three of these battalions were of the Indian Army, and one British. The Indian battalions were often segregated, with companies of different tribes, castes or religions. One and a half million volunteers came forward from the estimated population of 315 million in the Indian subcontinent.
Regimental battalions were not permanently allocated to particular divisions or brigades, but instead spent some years in one formation, and were then posted to another elsewhere. This rotating arrangement was intended both to provide all units with experience of active service on the Frontier, and to prevent them becoming 'localised' in static regimental stations. In contrast, the divisional locations remained constant.
Redesignating the regiments
To emphasise that there was now only one Indian Army, and that all units were to be trained and deployed without regard for their regional origins, the regiments were renumbered into single sequences of cavalry, artillery, infantry of the line, and Gurkha Rifles. Regimental designations were altered to remove all references to the former Presidency Armies. Where appropriate subsidiary titles recalling other identifying details were adopted. Thus the 2nd Bengal Lancers became the 2nd Lancers (Gardner's Horse).
The new order began with the Bengal regiments, followed by the Punjab Frontier Force, then the regiments of Madras, the Hyderabad Contingent, and Bombay. Wherever possible a significant digit was retained in the new number. Thus the 1st Sikh Infantry became the 51st Sikhs, the 1st Madras Pioneers became the 61st Pioneers, and the 1st Bombay Grenadiers became the 101st Grenadiers.
The Gurkha Regiments had developed into their own Line of rifle regiments since 1861. They were five of these until they were joined by the former 42nd, 43rd, & 44th Gurkha Regiments of the Bengal Army, who became the 6th, 7th, & 8th Gurkha Rifles. The numbers 42, 43, & 44 were allocated respectively to the Deoli and Erinpura Irregular Forces and the Mhairwara Battalion from Rajputana.
The mountain batteries had already lost their numbers two years earlier. Under the 1903 reforms they were renumbered with twenty added to their original numbers. The army had very little artillery (only 12 batteries of mountain artillery), and Royal Indian Artillery batteries were attached to the divisions. The Indian Army Corps of Engineers was formed by the Group of Madras, Bengal and Bombay Sappers in their respective presidencies.
The Corps of Guides composed of cavalry squadrons and infantry companies, was renamed the Queen's Own Corps of Guides (Lumsden's) but stayed numberless. The new regimental numbering and namings were notified in India Army Order 181, dated 2 October 1903.
