Meanwhile, in the smaller classes, the pair of works OSCAs had an ample lead of 15 laps over the struggling Porsches and running in the top-10 overall. Yet within ten minutes, with just 2 hours to go, everything fell apart. First, the leading one of Giardini crashed and rolled at Mulsanne, then the one running second hit the barriers at Dunlop curve. Pierre Leygonie ran the short distance back to the pits to get equipment and advice from the pit-crew. He managed to get it going again and back to the pits to hand over to Lance Macklin but they were then disqualified at race-end for having abandoned the car. To round off a bitter race for OSCA, their last car was running second in the S-1100 class but its transmission broke in the final laps of the race.
