Lance corporal
Lieutenant Richard Oliver Langham of the Royal Armoured Corps (RAC), who was originally a German citizen, was a member of an interrogation team which included Captain Frank Edmunds of the Intelligence Corps (IC). He was accused of having mistreated two former members of the Schutzstaffel (SS): and Rudolf Oebser-Roeder, who were suspected of helping to organise acts of terrorism. The two prisoners claimed to have been beaten up, tortured with lighted cigarettes, doused in cold water, and subjected to threats. Langham denied the claims, and cited medical records that showed that Roeder had not made any mention of his alleged mistreatment to the German doctor at the interrogation centre. For his part, Roeder claimed that he had not complained because he had thought the doctor was too "timid". Former Company sergeant major (CSM) Samuel Mathers testified that there had been no torture, though he admitted to having "pushed [the prisoners] around for a few minutes". Sergeant Edmund Sore told the court martial that he had been given orders by Mathers to "drive [Roeder] round the cell for about two hours", and Lance corporal A.R.S. Hunt testified that the reason given for the treatment was that the two Germans were "part of an organisation which was to start a rising on Hitler's birthday".
