On June 1, Haya, Rosa, Verdeguer and Lhakpa left C4 at 10 pm all together. Rosa turned around from the first slope above C4 due to problem in oxygen supply system. Verdeguer turned back from 8100m (about) due to oxygen problem. Haya and Lhakpa together reached up to 8200m. Haya's oxygen supply problem started there. Lhakpa gave him his oxygen (Russian) which work well but Lhakpa suggested Haya not to continue climbing alone. Then both of them turned back to C4. Ahead of them were Brazilians, Koreans, Singaporeans and another group was behind them.
