Sapper Frank Bonner

Sapper Frank Bonner served with 9th Field Company (Airborne) Royal Engineers and took part in the ill-fated Op Freshman mission to sabotage the German development of an atomic bomb at the Vermock Heavy Water plant in Norway.

Piloted by Sgt Doig and S/Sgt Strathdee in Airspeed Horsa Glider Serial number DP-349 and towed by Halifax tugs from 38 Group RAF, the mission flew from RAF Skitten, a Coastal Command Airfield four miles North-west of Wick, Scotland. Onboard were men from 9th Field Coy (Airborne) RE and 261 Field Park Coy (Airborne) RE, under command of Lt Methven, who had volunteered for the operation.

Taking off at 1745hrs on 19 November 1942, the mission soon became hampered by severe weather conditions. As the aircraft neared their intended targets the glider and tug encountered dense fog northwest of Rjukan which they were unable to emerge from. Fuel was getting low and as both tug plane and glider started to collect ice, they rapidly lost altitude. The glider released but crash-landed at Fylgjesdalen, north of Stavanger, killing the two pilots and six of the Airborne Engineers onboard (later buried at Eiganes Churchyard, Stavanger).

Nine members of those onboard Glider DP-349 survived the crash, although all were wounded, four of them with serious injuries. After initially receiving medical help from Norwegian locals in a farmhouse, all survivors were soon imprisoned as POWs by the Gestapo and taken to the Lagårdsveien jail on 23 November. Those less severely wounded were sent on to Grini concentration camp. Those who remained in Gestapo hands at Lagårdsveien were killed on 24-25 November and dumped at sea. Their bodies were never recovered.

Once at Grini concentration camp the five survivors were kept in solitary confinement until 18 January 1943 when they were collected by the German security police and conducted to Trandum, where they were shot in accordance with a decree from Hitler ordering the executions of Special Forces prisoners.

Sapper Bonner was amongst those killed whilst a Prisoner of War on 18 January 1943, aged 25 years old. Their bodies were finally recovered in August 1945 and Sapper Bonner was buried with full military honours at Vestre Gravlund, Western Civil Cemetery in Oslo.
