Desio wrote the official account of the ascent in his 1954 book La Conquista del K2 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 - at issue was the extent to which they had depended on support from other climbers high on the mountain, how they had treated Bonatti and Madhi, whether they used oxygen all the way to the top, and whether Desio's book was accurate and 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 CAI appointed three experts, called (the three wise men), to investigate. They produced a 39-page report in April 2004, but the CAI delayed until 2007 its publication of K2 - Una Storia Finita which included and accepted the report.
