It was an impressive first ascent up the relatively easier South Ridge via Shipton&rsquos Col from the Rhamani Glacier in the outer ring of the Nanda Devi sanctuary. The six members of the team who summitted Changabang in late June that year included some of the who&rsquos who of British climbing. The first was Chris Bonington himself, already a worldwide star. With him were Doug Scott, Dougal Haston and Martin Boyson, who were to form the cutting edge of Himalayan &lsquobig wall&rsquo mountaineering. Sandhu, on the other hand, would go on to become one of the finest ever Indian mountaineers. Sherpa Tashi Chewang, the other Indian to reach the summit, was a great mountaineer and rock climber, as well as a legendary instructor at Darjeeling&rsquos Himalayan Mountaineering Institute.
