Natha Singh belonged to Dhotian village in Amritsar. Sadda Singh was his father’s name. He joined the 23 Cavalry (Frontier Force) as a sowar. This force was part of the personal escort of Punjab’s Governor Michael O’ Dwyer. He came into contact with a Ghadar Party member Prem Singh of Sur Singh village. One of the major aims of the Ghadar Party’s programme was to persuade the Indian troops to join the movement. The Ghadar Party wanted to use the soldiers of India to overthrow British rule. The sowars of 23 Cavalry were won over by Prem Singh and they promised to march out and join the armed rebellion at the appointed hour.
