First of all, on 3 September orders were issued that strict respect for all rules of neutrality and compliance with all agreements of international law which were generally recognized were to be observed.
My Lord, that is D-55, Page 139.
THE PRESIDENT: In the British document book?
COL. PHILLIMORE: In the Defense document book—Dönitz-55.
And then, on 28 September, a warning was sent to neutrals to avoid suspicious conduct, changing course, zig-zagging, and so on. That is Dönitz-61, at Page 150. On 19 October that warning was repeated and neutrals were advised to refuse convoy escort. That is Dönitz-62, at Page 153. On 22 October there was a repetition of the warning, that is Dönitz-62, Page 162; and on 24 November the neutrals were told that the safety of their ships in waters around the British Isles and in the vicinity of the French coast could no longer be taken for granted. That is Dönitz-73, at Page 206; and then from 6 January onwards, certain zones were declared dangerous zones. That is right, is it not?
WAGNER: No. On 24 November a general warning was issued that the entire United States fighting zone was to be considered dangerous. The specific zones which since January were used as operational zones were not made public, since they came within the scope of the first warning and served only for internal use within the Navy.
COL. PHILLIMORE: That is the point I want to be clear about. The zones that you declared from 6 January onwards were not announced. Is that the point?
WAGNER: Yes, the neutrals were warned on 24 November that all of those zones which had been specifically declared as operational zones since January would be dangerous for shipping.
COL. PHILLIMORE: But when you fixed the specific zones from 6 January onwards, no further specific warning was given. Is that the case?
WAGNER: That is correct. After the general warning, we issued no further specific warnings about parts of this zone.
