On 5 December 1944 a British Douglas Dakota III aircraft, serial number FL588, of the Royal Air Force crashed on the Pic de la Camisette, a mountain close to the commune of Mijanès, Ariège, in the French Pyrenees. It was on a military transport operation during World War II. The Dakota was piloted by three RAF pilots. In total twenty-three airmen were on board, including twenty members of the Glider Pilot Regiment. Only six airmen survived the incident; sixteen died in the crash, another died within hours from his injuries. In spite of serious wounds, two of the survivors managed to reach the village of Mijanès to get help for the other survivors. FL588 originated from RAF Northolt in West London. Two Dakota planes took off at 09:00 on 5 December on a course for Marseilles transporting 20 glider pilots en route to India, who were trained to pilot Horsa and Hamilcar gliders to carry men and equipment. Around 15:30 one of the Dakota aircraft crashed on the Pic de la Camisette (alt 2426m ), striking the north face above the Roc de la Musique before coming down facing south-east near a lake. The exact cause of the crash is not known, although it is known that the aircraft came down in a blizzard. Seven pilots survived the crash initially, with varying degrees of injury but seven died during the night from injuries. The following morning, 6 December, the injured Blatch and Baker located Dawkins by following his cries of pain and attempted to bring him to shelter in the plane, but were unable to move him.
