His long and arduous career was now, however, fast drawing to a close. So early as the summer of 1854 it became evident that the health of General Sleeman was breaking up, and in the August of that year he was attacked by alarming illness. "Forty-six years of incessant labour," observes a writer at this date, "have had their influence even on his powerful frame: he has received one of those terrible warnings believed to indicate the approach of paralysis. With General Sleeman will depart the last hope of any improvement in the condition of the unhappy country of Oude. Though belonging to the elder class of Indian officials, he has never been Hindooized. He fully appreciated the evils of a native throne: he has sternly, and even haughtily, pointed out to the King the miseries caused by his incapacity, and has frequently extorted from his fears the mercy which it was vain to hope from his humanity." Later in the year. General Sleeman went to the hills, in the hope of recruiting his wasted health by change of air and scene; but the expectation proved vain, and he was compelled to take passage for England. But it was now too late: notwithstanding the best medical aid, he gradually sank, and, after a long illness, died on his passage from Calcutta, on the 10th February, 1856, at the age of sixty-seven. His Indian career was, indeed, long and honourable his labours most meritorious. He was one of those superior men which the Indian service is constantly producing, who have rendered the name of Englishman respected throughout the vast empire of British India, and whose memory will endure so long as British power shall remain in the East. It is well known that Lord Dalhousie, on his relinquishing the Indian Government, recommended General Sleeman and two other distinguished officers in civil employment for some mark of the royal favour, and he was accordingly nominated K.C.B., 4th February, 1856; of which honour his Lordship apprised him in a highly gratifying letter. But, however high the reputation of an officer placed in such circumstances--and none stood higher than Sir William Sleeman, not only in the estimation of the Governor-General and the Honourable Company, but also in the opinion of the inhabitants of India, where he had served with great ability for forty years, and won the respect and love particularly of the natives, who always regarded him as their friend, and by whom his equity was profoundly appreciated--it was to be anticipated, as a matter of course, that his words and actions would be distorted and misrepresented by a Court so atrociously infamous. This, no doubt, he was prepared to expect, The King, or rather the creatures who surrounded him, would at all cost endeavour to prevent any investigation into their gross malpractices, and seek to slander the man they were unable to remove.
