This is an incomplete list. Some of these regiments were reinforcements sent after the 1857 Mutiny began.
The East India Company had a three-tier system for its land forces. The majority of regiments were recruited by the East India Company from the local population, each with a couple of British officers. The EIC also had Indian regiments that were manned by whites. Last, the regular British Army stationed its regiments in India. Though India was not yet the "Jewel in the Crown", the Empire’s most valuable asset needed all the protection it was possible to provide. The British Government also wanted to ensure a firm control over the Company. This was not a case of a government protecting trade. London kept tightening its control over the EIC, till the latter became the commercial face of the British Government in India. This process came to its logical end whenLondon cancelled the EIC’s historic charter and seized direct control of India after the Mutiny erupted.
