SS 166/67/68 deck guns

[Drebbel]

I Assume the un-readable text is about some deck gun action ?

BTW: It took 2 torpedoes and 16 5 inch shells to sink the O 19 not to mention the placed charges. Of course, that might have been because the Dutch sub was lodged on a reef. There is a film somerwhere around documenting the incident. Anyone know where I could find that?

Actually just the transfer of the crew is filmed mainly. Also the submarine was never sunk, I have a 1952 movie that shows her still sitting on the reef with minimal visible damage !
