The facts are well-known: after a quarrel on the eve of the Le Mans 24h hours, John Surtees left Ferrari, angry with the antics of team manager Eugenio Dragoni, the same team manager who had already angered him by forcing him to drive the 312 in the Monaco GP instead of the more nimble 246 V6 trusted to number two driver Lorenzo Bandini. Every thing I have read in English, including in TNF, confirms this version, making Dragoni the villain of the episode, moved by his nationalistic wish to make Bandini the Scuderia main driver
Without doubting the story as conveyed by such an iconic figure as John Surtees undoubtedly is, I have always wondering what would be Dragoni's version -since I believe we shall always get the two sides of the story - but I never found any interview of the gentleman, his withdrawal at the end of the year seemingly confirming his apparent inability to solve the issue.
But digging in some Italian sources, I found a different perspective. According to Sergio Cassano in "Piloti and Gentiluomini, Gli Eroi Italiani della Ferrari", Dragoni was suspicious that Surtees was passing confidential information about the Ferrari P3 to his friend Eric Broadley at Lola who was building the T70 model. Ferrari send his right-hand man Franco Gozzi to investigate and upon his report decided to fire Surtees. Mauro Forghieri in "La Ferrari secondo Forghieri" shares the same angle but with a twist, an important one. According to him, it was Ferrari himself who was suspicious and had instructed Dragoni to make life as hard as possible to Surtees to provoke the rupture. Still according to Forghieri, believing that Dragoni had the power to fire Surtees is nonsensical (he uses the somewhat stronger Italian word "sciocchezza"), only Enzo able to do so. He admits that the controversy in the British press helped Dragoni's departure but says it was already planed beforehand.
At least, everybody agrees on one thing: had Surtees remained at Ferrari, Maranello would have most likely add another champions trophy to its collection.
So, do we have here a nationalistic plot to promote a protegé or a suspicious mind convinced that there was a case of industrial spying? Dragoni, the villain or Ferrari, the manipulator?
Perhaps someone in the Forum has more information to add to clarify what really happened almost 50 years go.
