Opinion about books

[notafinger!]

I am currently reading through Bungay's "Most Dangerous Enemy" and a paragraph of text on p. 164 has caught my attention.

The pressure to score also produced some transparent cases of dishonesty. One story has it that a famous German ace returned from a combat to claim three spitfires. His ground crew discovered that his guns had not been fired. His score went up, but his standing fell and the tale soon did the rounds.

Bungay cites the source as Caidin's "Me 109" p.141. Does anybody own this book or have further information on who this "dishonest German ace" may have been?
