From https://en.m.wikipedia.org/wiki/Blowing_from_a_gun

> George Carter Stent described the process as follows:[1]

>> The prisoner is generally tied to a gun with the upper part of the small of his back resting against the muzzle. When the gun is fired, his head is seen to go straight up into the air some forty or fifty feet; the arms fly off right and left, high up in the air, and fall at, perhaps, a hundred yards distance; the legs drop to the ground beneath the muzzle of the gun; and the body is literally blown away altogether, not a vestige being seen.

> ...

> The destroying of the body and scattering the remains over a wide area had a particular religious function as a means of execution in the Indian subcontinent as it effectively prevented the necessary funeral rites of Muslims and Hindus.[9] Thus, for believers the punishment was extended beyond death.
