The various motives assigned for the Mutiny appear inadequate to the European mind. The truth seems to be that native opinion throughout India was in a ferment, predisposing men to believe the wildest stories, and to act precipitately upon their fears. The influence of panic in an Oriental population is greater than might be readily believed. In the first place, the policy of Lord Dalhousie, exactly in proportion as it had been dictated by the most honourable considerations, was utterly distasteful to the native mind. Repeated annexations, the spread of education, the appearance of the steam engine and the telegraph wire, all alike revealed a consistent determination to substitute an English for an Indian civilization. The Bengal sepoys, especially, thought that they could see into the future farther than the rest of their countrymen. Nearly all men of high caste, and many of them recruited from Oudh, they dreaded tendencies which they deemed to be denationalizing, and they knew at first hand what annexation meant. They believed it was by their prowess that the Punjab had been conquered, and all India was held quiet. The numerous dethroned princes, their heirs and their widows, were the first to take advantage of the spirit of disaffection that was abroad. They had heard of the Crimean War, and were told that Russia was the perpetual enemy of England. Owing to the silladar system, under which the native cavalry provided their own horses and accoutrements, many of the sowars were in debt, and were in favour of a change which would wipe out the existing régime and with it the money-lender.
But in addition to these general causes of unrest the condition of the native army had long given cause for uneasiness to acute observers. During the course of its history it had broken out into mutiny at recurrent intervals, the latest occasion being the winter of 1843-1844, when there were two separate mutinies in Sind and at Ferozepur. Moreover the spirit of the sepoys during the Sikh wars was unsatisfactory, and led to excessive casualties amongst the British officers and soldiers. Both General Jacob and Sir Charles Napier had prophesied that the Mutiny would take place. Sir Hugh Gough and other commanders-in-chief had petitioned for the removal of India's chief arsenal from Delhi to Umballa; and Lord Dalhousie himself had protested against the reduction of the British element in the army. But all these warnings were disregarded with a blindness as great as was the incapacity that allowed the Mutiny to gather head unchecked after its first outbreak at Meerut. Moreover the outbreak was immediately provoked by an unparalleled instance of carelessness. It has recently been proved by Mr G. W. Forrest's researches in the Government of India records that the sepoys' belief that their cartridges were greased with the fat of cows and pigs had some foundation in fact. Such a gross violation of their caste prejudices would alone be sufficient to account for the outbreak that followed. (For the military incidents of the Mutiny see INDIAN MUTINY.)
