The D-types were now steadily hauling themselves back into contention. At midnight González/Trintignant were two laps ahead of Whitehead/Wharton. Manzon/Rosier were third, ahead of Rolt/Hamilton and the Aston Martins of Parnell/Salvadori and Collins/Bira completing the top six. The rain returned and the lead Jaguar had to pit again with fuel-line issues. After several more pitstops it finally retired with a broken gearbox. It joined Moss' car that had become undriveable after he had a total brake failure at the end of the Mulsanne straight doing 160 mph (taking two miles to stop on the escape road with hand-brake and gearbox!) Rolt and Hamilton however, managed to move into 2nd place by half-time, albeit still two laps adrift. Third was the other Ferrari, followed by the Spear/Johnston Cunningham and the supercharged Aston Martin. Just afterward, in an unusual co-incidence, "Prince" Bira crashed his Aston Martin, while running in 4th place, within yards of Thompson's Aston coupé that had crashed earlier. In the next hour, the Herrmann/Polensky Porsche, leading the S-1500 class and an impressive 7th place overall, retired with a blown head gasket. This left Macklin leading the class in the OSCA, a full 20 laps ahead of the Bristol leading the S-2000 class
