The newly unearthed diaries of an American assassin for the OSS - the forerunner of the CIA reveal that American spy chiefs wanted Patton dead because he was threatening to expose allied collusion with the Russians that cost American lives.
Military historian Robert Wilcox claims that OSS head General "Wild Bill" Donovan ordered highly-decorated marksman Douglas Bazata to do the killing.
He also alleged that when Patton began to recover from his injuries, US officials had agents of the Soviet NKVD, the forerunner of the KGB poison the general.
