Camp 020 had a resident medical officer, Harold Dearden, a psychiatrist who dreamed up regimes of starvation and of sleep and sensory deprivation intended to break the will of its inmates. He experimented in techniques of torment that left few marks — methods that could be denied by the torturers and that civil servants and government ministers could disown.
These techniques surfaced again after the war in a British interrogation facility at Bad Nenndorf, a German spa town, in one of the internment camps for those considered a threat to the Allied occupation.
In the four years after the war, 95,000 people were interned in the British zone of Allied-occupied Germany. Some were interrogated by what was now termed the Intelligence Division.
In charge of Bad Nenndorf was ‘Tin Eye’ Stephens, on attachment from MI5, and drawing on his Camp 020 experiences. An inmate recalled him yelling questions at prisoners and then punching them.
Over the next two years, 372 men and 44 women would pass through his hands. One German inmate recalled being told by a British intelligence officer: ‘We are not bound by any rules or regulations. We do not care a damn whether you leave this place on a stretcher or in a hearse.’
He was made to sleep on a wet floor in a temperature of minus 20 degrees for three days. Four of his toes had to be amputated due to frostbite.
A doctor in a nearby hospital complained about the number of detainees brought to him filthy, confused and suffering from multiple injuries and frostbite. Many were painfully emaciated after months of starvation. A number died.
