Encountered the Nelson in the fjord leading to Narvik.

Or maybe it was the Rodney. Its paint didn't seem to match that of either of them as shown in the recognition manual, but the structure seemed identical.
I fired four eels into her starboard side as the opening salvo, but scored only two hits.
I'm sure you can imagine the response from her escort.
Spent two+ hours being depth charged and pinged before finally shaking them by creeping acoss to the other side of the fjord at 130 meters with constant course changes. The Escorts finally gave up and proceeded on to Narvik (where they got their asses kicked) and I surfaced to find the immobile Nelson still chilling out where I initially hit her. I gave her one more torp from my stern, reloaded my front tubes and gave her two more from those. She finally went down.
I was pretty much a exhausted, nervous wreck after that fight, so I crept straight back to Wilhelmshaven. I only had one bow and one stern torp left anyway.
Not a bad haul though - my first Capital ship!
