Here the history of his arrest, as seen by himself:
"I was arrested on 11 March 1946 (at 11 pm).
My phial of poison had been broken two days before.
When I was aroused from sleep, I thought at first I was being attacked by robbers, for many robberies were taking place at that time. That was how they managed to arrest me. I was maltreated by the Field Security Police.
I was taken to Heide where I was put in those very barracks from which I had been released by the Bntish eight months earlier.
At my first interrogation, evidence was obtained by beating me. I do not know what is in the record, although I signed it. Alcohol and the whip were too much for me. The whip was my own, which by chance had got into my wife’s luggage. It had hardly ever touched my horse, far less the prisoners. Nevertheless, one of my interrogators was convinced that I had perpetually used it for flogging the prisoners.
After some days I was taken to Minden-on-the-Weser, the main interrogation centre in the British Zone. There I received further rough treatment at the hands of the English public prosecutor, a major.
The conditions in the prison accorded with this behaviour.
After three weeks, to my surprise, I was shaved and had my hair cut and I was allowed to wash. My handcuffs had not previously been removed since my arrest.
On the next day I was taken by lorry to Nuremberg, together with a prisoner of war who had been brought over from London as a witness in Fritzsche's defence. My imprisonment by the Intemational Military Tribunal was a rest-cure compared to what I had been through before. I was accommodated in the same building as the principal accused, and was able to see them daily as they were taken to the court. Almost every day we were visited by representatives for all the Allied nations. I was always pointed out as an especially interesting animal.
I was in Nuremberg because Kaltenbrunner's counsel had demanded me as a witness for his defence. I have never been able to grasp, and it is still not clear to me, how I of all people could have helped to exonerate Kaltenbrunner. Although the conditions in prison were, in every respect, good - I read whenever I had the time, and there was a well stocked library available - the interrogations were extremely unpleasant, not so much physically, but far more because of their strong psychological effect. I cannot really blame the interrogators - they were all Jews.
Psychologically I was almost cut in pieces. They wanted to know all about everything, and this was also done by Jews. They left me in no doubt whatever as to the fate that was in store for me.
On 25 May, my wedding anniversary as it happened, I was driven with von Burgsdorff and Bühler to the aerodrome and there handed over to Polish officers. We flew in an American plane via Berlin to Warsaw. Although we were treated very politely during our joumey, I feared the worst when I remembered my experiences in the British Zone and the tales I had heard about the way people were being treated in the East.

Here the history narrated in "Legions of Death" by Rupert Butler published in 1983,Hamlyn Paperbacks.
On 11 March 1946, a Captain Cross, Bernard Clarke and four other intelligence specialists in British uniforms, entered the home of Miss. Höss and her children.
The six men, we are told, were all "practised in the more sophisticated techniques of sustained and merciless investigation" (p. 235). Clarke began to shout:
"If you don't tell us [where your husband is] we'll turn you over to the Russians and they'll put you before a firing-squad. Your son will go to Siberia."
Frau Höss broke down and revealed, says Clarke, the location of the farm where her husband was in hiding, as well as his assumed name: Franz Lang. And Bernard Clarke added:
"Suitable intimidation of the son and daughter produced precisely identical information."
The Jewish sergeant and the five other specialists in third degree interrogation then left to seek out Höss, whom they surprised in the middle of the night, sleeping in an alcove of the room used to slaughter cattle on the farm.
<<Höss screamed in terror at the mere sight of British uniforms.
Clarke yelled "What is your name?"
With each answer of "Franz Lang," Clarke's hand crashed into the face of his prisoner. The fourth time that happened, Höss broke and admitted who he was.
The admission suddenly unleashed the loathing of the Jewish sergeants in the arresting party whose parents had died in Auschwitz following an order signed by Höss.
The prisoner was torn from the top bunk, the pyjamas ripped from his body. He was then dragged naked to one of the slaughter tables, where it seemed to Clarke the blows and screams were endless.
Eventually, the Medical Officer urged the Captain: "Call them off, unless you want to take back a corpse."
A blanket was thrown over Höss and he was dragged to Clarke's car, where the sergeant poured a substantial slug of whisky down his throat. Then Höss tried to sleep.
Clarke thrust his service stick under the man's eyelids and ordered in German: "Keep your pig eyes open, you swine."
For the first time Höss trotted out his oft-repeated justification: "I took my orders from Himmler. I am a soldier in the same way as you are a soldier and we had to obey orders."
The party arrived back at Heide around three in the morning. The snow was swirling still, but the blanket was torn from Höss and he was made to walk completely nude through the prison yard to his cell.>> (p. 237)
So it is that Bernard reveals "It took three days to get a coherent statement out of [Höss]" (ibid.).
