NOTES FOR CHAPTER XXVIII

1. The ‘schnorchel’ had first been fitted in a submarine by the Dutch. It was a ventilating tube that allowed the diesel engines to be used at periscope depth.
2. The Germans had informed the Japanese of their intentions and we had decrypted the Naval Attaché’s signals back to Tokyo.
3. They also had ‘legs’ which enabled them to sit under a ship’s bottom like an inverted table so that divers could work and place the charges.

 

4. British U class ex-Vortex.
5. Tapir intended to fire a full salvo of eight torpedoes but two tubes misfired, one going off later.
6. In 1945, Bomber Command laid 4582 mines, which sank 86 ships of 164,330 tons in the Baltic, and damaged another 35. They also sank four U-boats and damaged three others.
