I cruised into scapa flow after downloading GWX. I was playing at the beginning of the war I believe it was September 9th or somewhere around there. I had a field day, except for one small tanker! But that's ok it was my last torp that I decided to use on it, and when she didn't go down I gave it up to bad luck. I had enough good luck utterly ruining the rest of that naval base's anchored fleet of ships. I ended up destroying 4 or 5 destroyers, one troop transport, a couple of small merchants I believe, and something else but it escapes me at the moment.
And on ships exploding into pieces. While I was in scapa I destroyed 4 or 5 destroyers all with one shot each. They were only destroyers but it was impressive never the less to see the fireworks. Wish I would have taken some screenies. Only screeny I got of that patrol was when I first set sail, leaving the harbor. An appropriate mood it set for the greatest war in known history.
