Raja Harnam Singh was not the Maharaja of Kapurthala but one of his sons. Such a shame as this lineage goes back to Sultan Ul Quam Jassa Singh Ahluwalia.
These pictures are from a report by the SGPC, on the "Rape of Rawalpindi" in March 1947.
The Muslim League killed over 7000 Sikhs and made over 100,000 homeless in the space of some 6 or 7 days. This village pictured was a Sikh village which were forced to become Muslims or face the men being killed and their daughters and wives taken. The men capitulated in order to save their women in reality.
This village was where the men were all circumcised forcibly and had their heads shaved even though in islam for any male passing the age of 7 (I think) circumcision is not obligatory.
It was a very vicious campaign killing twice as many Sikhs as in November 1984, yet majority of Sikhs I've interacted with don't even know this.
Furthermore, it was the Sikhs who escaped Rawalpindi in March, who caused most bloodshed of the Muslims in Patiala, where the Sikhs were given refuge by Maharaja Yadvinder Singh. Maharaja Yadvinder Singh wrote in his memoirs about the Sikhs seeking refuge in his state, and it was most appalling what had happened to them.
