To begin with, domination of the European branch over the Indian branches was ensured. The commissions of 1859 and 1879 insisted on the principle of a one-third white army (as against 14% before 1857).  

• Finally, the proportion of Europeans to Indians was carefully fixed at one to two in the Bengal Army and two to five in the Madras and Bombay Armies.  
• Strict European monopoly over key geographical locations and departments, such as artillery, tanks and armed corps, was maintained.  
• Even the rifles given to Indians were of an inferior quality till 1900, and Indians were not allowed in these high-tech departments till the Second World War. 
• No Indians were allowed in the officer rank, and the highest rank an Indian could reach till 1914 was that of a subedar (only from 1918 onwards were Indians allowed in the commissioned ranks).  
• As late as 1926, the Indian Sandhurst Committee was visualising a 50% Indianised officer cadre for 1952.
