Bombay Sappers and Miners
The Bombay Sappers and Miners were part of the Indian Army Engineer Soldier Corps comprised the three armies of the Presidencies :-
- The Bombay Sappers and Miners (1777)
- The Madras Sappers and Miners (1780)
- The Bengal Sappers and Miners (1803)
Not to be confused with The Bombay Engineers being Engineers of one of the Honourable East India Company Armies. By the 1740’s each military administration of each presidency had its own cadre of British engineer officers, they were titled:- the Bombay Engineers, the Madras Engineers and the Bengal Engineers 
The Bombay Sappers and Miners originated from a company of 'Lascar Pioneer' in 1777, which was redesignated as 'The Pioneer Corps'. In 1799 a 'Corps of Engineer Lascars and Pontoon Train' was raised its was later renamed the 'Sapper and Miners Company' and by 1820 was merged with the Pioneer Corps. In 1830 it was called the 'Engineers Corps' and seven years later the 'Corps of Bombay Sappers and Miners' (1837). With the Kitchener Reforms in 1903 it was re-titled '3rd Sapper and Miners' and in 1923 become the 'Royal Bombay Sapper and Miners'. In 1941 they became the 'Royal Bombay Sappers and Miners Group' of the Indian Engineers in 1946 the 'Bombay Group' of the Royal Indian Engineers . The senior Officers were British and the loosely organised military units were later combined into battalions with Indian officers commanding local troops. Officers were in the early years very conscious of the soldiers' local customs, caste rituals, dress, and social hierarchy.
