During the ascent, Angerer was injured by falling rocks loosened by the warmth of the rising sun as they crossed the first ice field. As a result of Angerer's worsening condition and their slow progress across the second ice field, they abandoned the attempt on the Eiger and decided to descend. A further challenge arose when Kurz and his comrades failed to retrace their route across the area now known as the Hinterstoisser Traverse and had to climb downwards. As the result of another avalanche, Hinterstoisser himself became disconnected, plummeted down the mountain, and perished. Later, Willy Angerer, now climbing below Kurz, was smashed against the wall, dying instantly. Edi Rainer, the climber who had been securing the other two, was pulled against the wall and died minutes later of asphyxiation. Kurz, alone now, remained uninjured.
