An account of the German expedition to Nanga Parbat in 1934. This expedition, led by W. Merckl, included strong climbers such as Willo Welzembach. The top team reached an altitude of 7,850 metres, but were surprised by a terrible snowstorm. Some decided to descend, others to wait for an improvement. The very poor conditions and the heavy snowfall made the retreat catastrophic: Wieland, Merckl, Welzembach and six sherpas lost their lives. With the death of Drexel at the start of the expedition, a victim of mountain sickness, this tragic expedition resulted in the disappearance of 10 people. - BAUER (Paul): Auf Kundfahrt im Himalaya.
