Lord Dalhousie, Governor-General in 1854, saw the danger of this great preponderance of Native troops.

He represented that the annexations and conquests which had taken place during his tenure of office necessitated a proportional increase of British soldiers; he protested against the withdrawal of a single European regiment, either on account of the war with Russia or for operations in the Persian Gulf, and he solemnly warned Her Majesty's Government that the essential element of our strength in India was the presence of a large number of British troops.
No attention, however, was paid to Lord Dalhousie's representations by the authorities in England, who doubtless thought they understood the requirements of India better than the Governor-General, with his more than six years' experience of the country.

In spite of his remonstrances, two regiments were ordered to England, and four were sent later to the Persian Gulf, with the result which I have already stated.
When the Mutiny broke out, the whole effective British force in India only amounted to 36,000 men, against 257,000 Native soldiers,[5] a fact which was not likely to be overlooked by those who hoped and strived to gain to their own side this preponderance of numerical strength, and which was calculated to inflate the minds of the sepoys with a most undesirable sense of independence.

An army of Asiatics, such as we maintain in India, is a faithful servant, but a treacherous master; powerfully influenced by social and religious prejudices with which we are imperfectly acquainted, it requires the most careful handling; above all, it must never be allowed to lose faith in the prestige or supremacy of the governing race.

When mercenaries feel that they are indispensable to the maintenance of that authority which they have no patriotic interest in upholding, they begin to consider whether it would not be more to their advantage to aid in overthrowing that authority, and if they decide that it would be, they have little scruple in transferring their allegiance from the Government they never loved, and have ceased to fear, to the power more in accordance with their own ideas, and from which, they are easily persuaded, they will obtain unlimited benefits.
A fruitful cause of dissatisfaction in our Native army, and one which pressed more heavily upon it year by year, as our acquisitions of territory in northern India became more extended, was the sepoy's liability to service in distant parts of India, entailing upon him a life amongst strangers differing from him in religion and in all their customs, and far away from his home, his family, and his congenial surroundings--a liability which he had never contemplated except in the event of war, when extra pay, free rations and the possibility of loot, would go far to counterbalance the disadvantages of expatriation.
