This is a secret paper that was written by Colonel Sir Bruce Seton to address the question of the degree of prevalence, if any, of self-infliction of wounds among Indian troops.
Col Seton analysed 1,000 cases which had passed through the Kitchener Indian Hospital in Brighton. He was able to quickly eliminate 307 as being wounds which could not have been self-inflicted, either because they were to a vital part of the body, such as the head, or they were inflicted in combat, such as bayonet wounds or gassing.
Of the remaining cases, Col Seton focused on the 280 wounds to the wrist and hands. By analysing the causes of the wounds (by shell or bullet), and whether the wound was to the right or left hand, it was found that only six could possibly have been self inflicted. The conclusion of the paper is that there was no evidence of self-infliction of wounds which could be supported by statistical analysis.
