In 1956, members of an Austrian Karakorum Expedition climbed Gasherbrum II peak (8035m/26,361ft). The party was led by Fritz Moravec.
It set a base camp on the south Gasherbrum glacier. Camp-I, was set up at 6005m/19,700ft. It was here that the party was forced to stay for ten days because of a severe storm. Consequently, it lost a large supply store in an avalanche. After setting up a few more camps, Fritz Moravec, Josef Larch and Hans Willenpart set up a bivouac below 7,620m/25000ft. Inspite of receiving bivouac, the three reached the summit of Gasherbrum II on the 8th July and came back without meeting any further accident.
