NOTES FOR CHAPTER VIII

1. Captain Voelcker was relieved at Blyth in command of the Sixth Submarine Flotilla in March by Commander GC Phillips DSO RN and took over the Maidstone to form the Eighth Flotilla at Gibraltar.
2. Details of these attacks have been lost.
3. This was one of the first occasions on which the new flashless cordite was used.
4. Captain SW Roskill RN in “The War at Sea”.
5. Only two submarines were lost in the Mediterranean during the same period.
6. Thetis had been lost on trials, but was being salvaged.
7. These new U-class differed from the three pre-war submarines in that the two external torpedo tubes were omitted. It had never been

found possible to fire a salvo of six torpedoes without breaking surface. A Q tank forward of amidships had been included in the design but even so it was considered that the four internal tubes would be sufficient and this would allow four reloads to be carried as well as a gun. The external torpedo tubes had already been ordered and they
were used as a single stern tube for the new S-class and a third stern tube for the new T-class building, the midship tubes having been turned round to face aft. These tubes were also used to give Severn and Clyde a pair of stern torpedo tubes.
8. These boats were cancelled later in 1941.
9. There was, because of superstition, no P213.
