History of the Ordnance Department
In 1775 the East India Company established the 'Board of Ordnance' at Fort William, in Calcutta. In 1787 a gunpowder factory was established at Ishapore which started production in 1791. In 1801 a 'Gun Carriage Agency' was set up at Cossipore that started production in 1802. In 1906 the administration of Indian Ordnance factories came under the 'Inspector General of Ordnance Factories'. This changed again in 1936 to the 'Director of Ordnance Factories .
The following Ordnance Factories have been identified as having railways (see separate pages for more information):-
- Cossipore, Gun and Shell Factory

Carnatic Ordnance Artificers
In June 1821, the Governor in Council authorised the formation of a corps of Carnatic Ordnance Artificers, to be recruited from the sons of Europeans born in India and to be enlisted as European soldiers. They were to come from the Orphan Asylum, the fort school, and from other charitable institutions. One of the reasons for the establishment was the desirability of providing suitable employment for a portion of the Eurasian (mixed race) population. The Corps was attached to the Gun Carriage Manufactory
An artificer, or artifier, has the general meaning of craftsman, and the meanings also include ‘A military mechanic, as a blacksmith, carpenter, etc.; also, one who prepares the shells, fuses, grenades, etc., in a military laboratory’ and 'A member of the military who specializes in manufacturing and repairing weapon systems' (Carnatic is a term for South India, and refers to Madras Presidency)
