M. DUBOST: Did you know where they came from?
LAMPE: It was very difficult to know from what camp they came because, as a general rule, they were isolated when they arrived in camp. They were taken either direct to the prison or else to Block 20, which was an annex of the prison, about which I shall have occasion . . .
M. DUBOST: How did you know they were officers?
LAMPE: Because we were able to communicate with them.
M. DUBOST: Did all of them come from prisoner-of-war camps?
LAMPE: Probably.
M. DUBOST: You did not really know?
LAMPE: No, we did not know. We were chiefly interested in finding out of what nationality they were and did not ask other details.
M. DUBOST: Do you know where the British, American, and Dutch officers came from, about whom you have just spoken and who were executed on the steps leading to the quarry?
LAMPE: I believe they came from the Netherlands, especially the Air Force officers. They had probably bailed out after having been shot down and had hidden themselves while trying to go back to their lines.
