As the team descended, Mr Kinloch's guides noticed that he seemed to lose co-ordination. He would slip and stumble, then resume walking normally. After an hour, he made a surprising request to the team leader, David O'Brien, to be shown how to get down the ladders. At first he said he was having difficulty seeing, then he admitted that he could not see anything.
It took four hours for Mr O'Brien and a sherpa to help the stricken climber down to Mushroom Rock, barely 1,000ft below the summit. Two more sherpas arrived and for the next eight hours they all struggled to bring Mr Kinloch,28, down the mountain, administering drugs and oxygen. But they were now dangerously close to needing rescue themselves, and had to abandon him and struggled back into camp at 5.30am, exhausted and suffering from hypothermia and frostbite.
RIP Peter Kinloch.
