Type VII B/C u-boats are listed as carrying 14 torpedoes total. How were these stowed?

As far as I can tell:

A. Forward Torpedo Room
- 4 torpedoes in the tubes
- 4 torpedoes underneath the deck plates
- 2 in the bunk space ? Where exactly were these stored? Did they prevent access to tubes III and IV, and the torpedoes inside them ?

B. Aft Torpedo Room
- 1 torpedo in tube V
- 1 torpedo under the deck plates in the motor room

C. External storage
- 1 torpedo on fore deck
- 1 torpedo on aft deck

Can anyone confirm this and answer my questions?

Thanks,

Dan
