25.10.1939: U-30 (Typ VIIB)
Cruising my way to AM19 when I happen across the Rodney escorted by one C & D class destroyer and two Southampton Class vessels that I can see. They are doing 22knots and have a range of about 4,200 metres in clear weather but moderate seas. They are literally crossing my T and all I have to do is grow a pair and do the necessary calculations (albeit...quickly!) I dive to periscope depth, cross my fingers (I only have 70 metres under the keel), open all four forward tubes, set depth to 12.5m, magnetic fuses, with a spread of 0.8 degrees and let loose. Three minutes into the run two premature detonations - surely that would alert the British...apparently not.
I move to the hydrophone and start lestening. I listen...listen some more....keep listening...STILL listening...start cursing the waste of four eels when, 4:47 seconds after firing, I hear a single detonation. Up periscope: it's the Rodney in the midst of a fireball. It appears the eel detonated under the boiler room and just smashed it pieces. In under two minutes she's disappeared beneath the waves and her escorts are not real happy about it. Thankfully that at such a long range, the escorts have no idea where to look.
At this point, I double back on my course at silent speed secretly wishing I had externals on to take some shots of it. End result: one eel = 36K tons of battleship to the bottom and one VERY lucky Kaleun.
Currently loitering in the Rockall Bank region (as per orders) and there is nothing but rubbish weather upstairs.
Gotta say, I think I used up all my luck with that one eel.
