(Continuation of my earlier report)
U-336 has been shadowing the convoy at AL23, going ENE/6 knots.
We made several passes through the convoy at periscope debt, using the very bad weather (about 100m of visibility

) to our advantage.
0045 - Another pass through the convoy
Destroyer attacking! bearing 264!
I turn the periscope around to see a bow coming up in the fog. It's wide. Too wide for a DD. Wait, it has a deck house with 3 windows? A tanker?
She passes by behind us.
HMS Nelson
Created some distance, turned around and plotter her course. They're not aware of me yet.
01:46
Fired a 2 torp, 2 degree torpedo salvo at the Nelson..hope for the best.
01:46 (+26 seconds) Torpedo treffer! - Torpedo treffer!
01:49 Visual with the Nelly regained...she's dead in the water.
It takes her hours, slowly but surely her stern settles deeper and deeper into the water.
06:10. Nelly goes down.
-----
Returning to Lorient...We took some bad damage earlier, and only have 2 fish left.
08:13: Large allied, Convoy, AL23 heading east 5 knots. 50 ships, 10 escorts.
I'm happy taking just the Nelly
