On 19 November 1921, about 100 Moplah prisoners were sent by train from Malabar to Coimbatore. They were packed in goods wagons which, of course, had no ventilation. So, when the doors were opened after a five hours' journey, the prisoners were found to be in a state of collapse, with horrible wounds inflicted by bites and bows in one another by the struggling men. In all, 82 men died. In the aftermath of this ethnic cleansing, the Suddhi Movement was created by the Arya Samaj. They converted over 2000 Hindus who had been forcibly converted to Islam by the Moplahs. However their leader, Swami Shraddhananda, had to pay with his life, due to this effort. The aged Swami was stabbed on 23 December 1926 by a person named Abdul Rashid at his Ashram.
