BdU gave us a special mission, according to some information Scapa Flow had 2 Battleships stationed in her port.
And BINGO!, HMS Hood was there..then around 10 km to west of her I found HMS Nelson.
Game crashed so I had to restart

but...it was all the same except I raided Scapa at night not in the day
Hood going down
Took me 2 eels to sink Nelson while Hood took me 7-8 and at least 3 of them bounced against her hull and found 1 Auxiliary Cruiser which only took me 1 eel to sink.

Nelson throwing flares

More flares

The fireworks visible from the bridge, I had little risk of being caught since it was night and I tried to load my remaining torpedos into the u-boat, but I only was able to load 2 before Destroyers found me and started to shot at me, in less than 1 minute my hull was down to 58%.
100k tons in 1 patrol.....not bad
