From the end of 1857, the British had begun to gain ground again. Lucknow was retaken in March 1858. On 8 July 1858, a peace treaty was signed and the war ended. The last rebels were defeated in Gwalior on 20 June 1858. By 1859, rebel leaders Bakht Khan and Nana Sahib had either been slain or had fled. "As well as hanging mutineers, the British had some "blown from cannon"-- an old Mughal punishment adopted many years before in India. A method of execution midway between firing squad and hanging but more demonstrative, sentenced rebels were set before the mouth of cannons and blown to pieces." [87] In terms of sheer numbers, the casualties were significantly higher on the Indian side. A letter published after the fall of Delhi in the "Bombay Telegraph" and reproduced in the British press testified to the scale and nature of the retaliation:
.... All the city people found within the walls (of the city of Delhi) when our troops entered were bayoneted on the spot, and the number was considerable, as you may suppose, when I tell you that in some houses forty and fifty people were hiding. These were not mutineers but residents of the city, who trusted to our well-known mild rule for pardon. I am glad to say they were disappointed. [88]
Another brief letter from General Montgomery to Captain Hodson, the conqueror of Delhi exposes how the British military high command approved of the cold blooded massacre of Delhites: "All honour to you for catching the king and slaying his sons. I hope you will bag many more!"
Another comment on the conduct of the British soldiers after the fall of Delhi is of Captain Hodson himself in his book, Twelve years in India: "With all my love for the army, I must confess, the conduct of professed Christians, on this occasion, was one of the most humiliating facts connected with the siege." (Hodson was killed during the recapture of Lucknow in early 1858).
Edward Vibart, a 19-year-old officer, also recorded his experience:
It was literally murder... I have seen many bloody and awful sights lately but such a one as I witnessed yesterday I pray I never see again. The women were all spared but their screams on seeing their husbands and sons butchered, were most painful... Heaven knows I feel no pity, but when some old grey bearded man is brought and shot before your very eyes, hard must be that man's heart I think who can look on with indifference...
Some British troops adopted a policy of "no prisoners". One officer, Thomas Lowe, remembered how on one occasion his unit had taken 76 prisoners - they were just too tired to carry on killing and needed a rest, he recalled. Later, after a quick trial, the prisoners were lined up with a British soldier standing a couple of yards in front of them. On the order "fire", they were all simultaneously shot, "swept... from their earthly existence". This was not the only mass execution Lowe participated in: on another occasion his unit took 149 prisoners, and they were lined up and simultaneously shot.
As a result, the end of the war was followed by the execution of a vast majority of combatants from the Indian side as well as large numbers of civilians perceived to be sympathetic to the rebel cause. The British press and government did not advocate clemency of any kind, though Governor General Canning tried to be sympathetic to native sensibilities, earning the scornful sobriquet "Clemency Canning". Soldiers took very few prisoners and often executed them later. Whole villages were wiped out for apparent pro-rebel sympathies.
The aftermath of the rebellion has been the focus of new work using Indian sources and population studies. In The Last Mughal, William Dalrymple examines the effects on the Muslim population of Delhi after the city was retaken by the British and finds that intellectual and economic control of the city shifted from Muslim to Hindu hands because the British, at that time, saw an Islamic hand behind the mutiny. [89] Amaresh Mishra, a journalist and history student, after examining labor force records for the period, concludes that almost ten million Indians lost their lives during the reprisals though his methodology is disputed because it neither accounts for unrelated causes of deaths nor for the movement and displacement of the population that likely followed that period of unrest. It has to be noted that Mishra's version of events is dramatically different from the traditional view held by most historians. Accounting for these factors, another historian, Saul David, estimates the number of deaths to be in the hundreds of thousands [90] .
