In the race, Hermann Lang led the first few laps but retired with a broken damper, and British driver Richard Seaman followed shortly after.
The lead changed hands several times between Manfred von Brauchitsch, Bernd Rosemeyer and Rudolf Caracciola.
Rosemeyer stayed in the lead until the end and took the win after 80 laps, with four other German cars completing the full distance within the next minutes before the race was flagged off for good.
Half a minute later came the deeper note of a 2.9-litre Maserati, and "B. Bira" (Prince Birabongse of Siam, Mays’ nearest rival and a new star in the racing firmament) shot past us, cornering with that precision which marked him as the master he was.
The two cars took the hairpin, von Brauchitsch almost sideways, and rocketed away out of sight with long plumes of rubber smoke trailing from their huge rear tyres, in a deafening crash of sound.
