Selected Extracts
Commanding Admiral, Submarines and Group West receive the following directive (Ski. I op 287/40):

n 65 n are to be disposed off Bergen and Stavanger for the present
2. Unseen approach and disposition, radio silence.
3. Assignment: Attack and report on possible British troop transports and warships which are about to effect landings in these ports. No operations against merchant shipping.

Kriegstagebücher (KTB) - War Diary
U 38 and U 52 have been allocated operations areas on the Norwegian coast. (see Appendix 1 to War Log).
U 31 did not return from her trial runs in the Schilling Roads. Search showed that she had sunk near Black Buoy No. 12, after an attack by an English A/C. (Details of this accident are set out in Appendix 2 to War Log). It is particularly regrettable that a boat should have been lost by enemy action in the immediate vicinity of her own base, inside our own barrage defenses. Losses of this kind should be avoidable. This is the second time that an enemy A/C has flown very low over the Schilling Roads and attacked U-boats. We must have sufficient AA defenses for the approach route on the Jade so that at least the enemy is prevented from flying low undisturbed. B.d.U. has made demands accordingly.

Certain FAA CAGs were intensively training in Night operations. This was to deliver dividends over the next year, but learning to fly at night on combat conditions was hazardous. In night air accident, a Swordfish of 823 Squadron crashed at Hal Far. Lt T W G French, Naval Airman J O'Riley, and LAC G A Lawrence of 812 Squadron were killed.
