Fifty years ago, in the summer of 1956, Mr. Newby set out on the trip that would make him famous: a voyage by station wagon, foot and horseback to climb Mir Samir, a 20,000-foot peak in Nuristan, a wild region in northeastern Afghanistan. The fact that he had never climbed a mountain did not deter him in the slightest.
Mr. Newby chronicled the trip in “A Short Walk in the Hindu Kush,” published in Britain by Secker & Warburg in 1958 and in the United States by Doubleday the next year. As in all his work, the narrative was marked by genial self-effacement and overwhelming understatement.
