Two Sherpas were at Camp IV after an abandoned rescue with instructions to reach Wolfe if they could. The leader of the expedition, Fritz Wiessner, asked two Sherpas at Base Camp to make another rescue attempt. Tsering Norbu, with Pasang Kikuli as leader, left Base Camp at 06:00, were at Camp IV by noon, and met the other Sherpas by the end of the day at Camp VI. By climbing in one day they made the sort of alpine-style Himalayan ascent only achieved decades later by western climbers. With Tsering Norbu staying at Camp VI, Pasang Kikuli, Pasang Kitar and Phinsoo reached Wolfe at noon, 29 July.
