They also continued climbing, in addition to which Julie studied traditional Japanese martial arts, under David Passmore in the Budokan school, Tunbridge Wells.
In 1981, Diemberger hired Tullis as a technician for an expedition to Nanga Parbat, and their high-altitude filming career began.
All the trapped climbers deteriorated physically and mentally, lacking food, sleep, oxygen and, once the gas for the stoves ran out, the ability to melt snow and produce water.
This, in turn, made them vulnerable to pulmonary or cerebral oedema, which in Tullis' condition would have been rapidly fatal.
Tullis died on the night of 6/7 August (the accounts of Diemberger and another climber present, Willi Bauer, differ on the date) and was buried on the mountainside.
