In fact, Major Khurshid Anwar had already mobilised the Pashtun tribes from the Frontier for a raid on Kashmir and was poised to launch his attack on 15 October. When the tribal invasion was launched on 22 October 1947, Khurshid was still in the Valley. He was arrested on 2 November 1947 by the State Police, who recovered maps and documents from him. Indian sources say that Khurshid had gone underground and was attempting to organise an agitation against the state government from the Jama Masjid, the hub of activity for the Muslim Conference. Khurshid remained in custody until a prisoner exchange in 1949, after the Karachi Agreement was signed by India and Pakistan.
