Throughout the expedition Wolfe and Alice wrote each other loving letters. At Srinigar at the start of the expedition proper Wolfe was dismayed to find out that Wiesner had not taken his advice to bring two-way radios. On the march-in to K2 base camp Wolfe coped as well as anyone else and started off strongly when it came to climbing the mountain. However, above Camp II he was noticeably slow and was criticised for this by some of his colleagues. Wiessner favoured him over the other team members because he was less complaining and had good endurance. He did not take any sort of lead, however, and merely plodded up to each camp after it had been established by other climbers. In this way he got further up the mountain than any of the Americans except Wiessner.
