NOTES FOR CHAPTER IV

1. L23, L26, H43, H44, H49 and H50.
2. With Commander GWG Simpson RN as Commander (S).
3. Particular anxiety was felt for the airfield at Banak, which was the only one suitable for bombers in North Norway. We hoped to use it to, among other things, mine the approaches to Lulea to stop the summer ore traffic. The Germans had a plan to use their fast trans-
Atlantic liners Bremen and Europa to send a force to this area. There was also suspicion that the Russians might help the Germans to attack using their merchant ships interned in Murmansk, or indeed that they might try to seize Northern Norway for themselves as they had seized Eastern Poland in 1939.
4. Although a collision with Wilk cannot be ruled out or indeed a combination of both.
5. Not to be confused with Kristiansand in the Skagerrak.
6. Porpoise had difficulty in getting a report through of her
minelaying by wireless and her position may have been compromised with the enemy using direction-finding stations.
7. Trident in Fro Havet
Triton off Kya Light
Sunfish off the Dutch coast
Severn off Utsira
Truant approaching Trondheim area
Tribune at Skudenes
Salmon at Lister
Snapper bound for Jaederens
8. H28, H31, H34, H44 and H49.
9. Ursula, Spearfish, Swordfish and Sturgeon from Blyth also took part in these patrols.
10. Some of the torpedo tubes in the other French submarines were small ones of 400 mm (15.7') diameter and there were no torpedoes of this size available in the United Kingdom. Rubis, Junon and Minerve also had Vickers-Normand diesel engines that it was possible to maintain in British shipyards.

11. Here they were available to provide spare periscopes, batteries and other equipment of French manufacture to keep the operational submarines in service.
12. They had been manufactured for Torbay, Talisman and Tetrarch, which originally were to have been minelayers with minelaying tubes through their saddle tanks.
13. Rubis was recalled to France before this sortie but was allowed to make it at the request of the Admiralty. The French wished the operation to be broken off if an armistice was signed. The Armistice was signed before the mines were laid on 22nd June. This was due to
‘communication difficulties’,
14. The Type 138, which was an asdic oscillator mounted on the casing with hand training, a ‘dustbin’ dome and a receiver. It could not transmit and could only be used submerged but gave these submarines as
good a set when used as a hydrophone as any modern submarine.
15. I think in fact this was the torpedo boat Luchs.
16. Protosorb spread in trays absorbs carbon dioxide and was now being issued to submarines. Sealion carried an oxygen cylinder too.
17. Her track went right through the position of a newly laid field but recent research shows that she probably did so just before it was laid. However she passed close to another field and a navigational error could have taken her through it.
18. Trondheim. In mid August there were over eight hours of darkness in the Skagerrak and seven hours off
19. Including the second sortie by Thor.
20. Including Samland.
21. He was thought at the time to have sunk a U-boat, a claim that has not been substantiated from enemy records.
