First of all, forgive my rusty, mouldy english
Well, took me bout an hour to check some info
in not-so-unknown sources as
www.uboatarchive.net
from where I will show extracts of interrogatories
carried on surviving U-boat crews.
U-175
U-199
U-701
and on diverse places as the book on Luth "U-boat Ace" by Jordan Vause,
www.uboat.net on Robert L Holt sunk by U-69
adn definitely the Kriegstagebuch from U-625 on sinking
the damaged SS Empire Sky
Well, I added a match and brought more fuel to the question, perhaps.
But I think it would be quite fair reconsider the statement "U-boat never carried AP or SS" that i read in quite a number of posts.
And if so, at least i would leave the gap for a future add of incendiary (as AA maybe was almost useless in 105, maybe) ??
Besides i've seen about 3 up to 5 types of ammo for the smaller guns,
which i'll not mention here now, from same and other sources.
Cheers all out there,
Happy hunting
