Desio wrote the first official account of the expedition in his 1954 book but this account was disputed over many years by Bonatti and, eventually, Lacedelli and others. That Compagnoni and Lacedelli had reached the summit of K2 was not in dispute - the issue to begin with was how the lead climbers had treated Bonatti and Mahdi who, high on the mountain, had been carrying up oxygen cylinders for them. Later there was a dispute about whether the oxygen had run out before or after they had reached the summit. Overall, Bonatti claimed Desio's book was neither accurate nor fair. The matter became increasingly controversial with a great deal of press criticism, often uninformed. Desio died in 2001 at the age of 104 and eventually in 2004 the Club Alpino Italiano appointed three experts, called (the three wise men) to investigate. In 2007 the CAI published K2 - Una Storia Finita (referred to as CAI 2007 in this article) which included the report and accepted, and expanded on, its contents. In short, the CAI report accepted Bonatti's version of events.
