NOTES FOR CHAPTER XV

1 On arrival the cruiser Cleopatra acted for a while as depot ship. Later the submarine crews were accommodated in a transit camp ashore and in local hotels.
2. She intended to fire three torpedoes but the fourth was fired due to a drill error.
3. Details of this attack were lost with the submarine.
4. Another enemy account says Pegaso sank her after making two unsuccessful attacks on a tanker, but this is unlikely.
5. The new U-class had a 3” gun as fitted in the first three boats of the U-class. This was a superior weapon to the 12pdr on an AA mounting as fitted in the next 22 boats.
6. There is a difference of opinion on how P42 came to be in an intercepting position off the Lipari Islands when she had definite orders to patrol off Cape Milazzo. Admiral Simpson states in ‘Periscope View’ that he gave P42 orders to withdraw from Cape Milazzo if he met stiff opposition there, which he did. Alastair Mars says in
Unbroken’ that he moved as he considered it was a better place to intercept the Italian cruisers.
6a. In the final stages of the passage of the ‘Pedestal’ convoy, the patrol line off Pantellaria was ordered to surface and show themselves as a deterrent. There is no indication that this unusual tactic had any effect, as the Italian cruisers had already been ordered north of Sicily
to transit the Straits of Messina.
7. These were either CCR or Duplex pistols, the salvo consisting of a mixture of both types.

8. An enemy source says she sank two ships totalling 10,623 tons on 16th August.
9. One of 8325 tons shared with the RAF.
10. This was a Sunderland flying boat. Talisman dived on sighting it but did not fire a recognition flare.
11. Running stores to Malta, Clyde from Gibraltar, Porpoise from Port Said and Rorqual from Beirut. Passage and running stores to Malta from Gibraltar Parthian. Passage home to refit, Proteus and P34.
12. Maximum diving depth was 300 feet.
13. In her Adriatic patrol P211 had made use of dummy periscopes devised by Captain(S) Ten to confuse the enemy. She spread four of these throughout the Adriatic.
14. It took three and a half hours and some manhandling to persuade the two agents to land in accordance with their orders.
15. Two of these were shared with aircraft.
16. One shared with aircraft.
17. It is often very difficult to reconcile such figures. Sometimes they relate only to ships carrying cargo to North Africa and sometimes to all ships in the Mediterranean. Sometimes they refer to the number of ships and sometimes to the tonnage. Sometimes they refer to Italian ships, sometimes to German and sometimes to both. French or Yugoslav ships are liable to be omitted.
18. At the Italian Armistice a year later, they had some 700,000 tons of shipping remaining.
