Sita Ram was a sepoy who remained loyal to the British. Yet even he had his "doubts" about them. The following is an excerpt from memoirs he wrote sometime in the 1860s about the rebellion.
It is by chance that about this time the English Government sent parties of men from each regiment to different garrisons for instruction in the use of the new rifle. These men performed the new drill for some time until a report got about, by some means or other, that the cartridges used for these new rifles were greased with the fat of cows and pigs. The men from our regiment wrote to others in the regiment telling them of this, and there was soon excitement in every regiment.
Some men pointed out that in forty years of service nothing had ever been done by the English Government to insult their religion, but as I have already mentioned the sepoys' minds had been inflamed by the seizure of Oudh​. Interested parties were quick to point out that the great aim of the English was to turn us all into Christians and they had therefore introduced the cartridge in order to bring this about, since both Muslims and Hindus would be defiled by using it. . ..
[The Proclamation of the King of Delhi] stated that the English Government intended to make all Brahmins into Christians, which had in fact been proved correct, and in proof of it one hundred ministers were about to be stationed in Oudh. Caste was going to be broken by forcing everyone to eat beef or pork. . ..
I had never known the English to interfere with our religion or our caste in all the years since I had been a soldier, but I was nevertheless filled with doubt. . .. I had also remarked the increase in Missionaries during recent years, who stood up in the streets of our cities and told the people that their cherished religion was all false, and who exhorted them to become Christians.
