So, on my way to my patrol grid around a month prior to Weseruebung, I did a routine dive in the middle of the North Sea. Immediately my hydrophonics guy started going crazy, reporting contact after contact after contact - clearly a convoy, but one much bigger than I've ever stumbled across before!
I shadowed them until nightfall, then pulled into visual range to line up an attack. What I found was what must be a 40-50ship convoy... but they all seem to be Norwegian!? They're certainly escorted by the Royal Navy, but all the flags on the merchants that I can make out are Norwegian.
Is this a scripted convoy for mission to Norway I didn't know about (playing GWX Gold, no other mods)? It's early in the morning (around 3:00am) on March 6th 1940, with the convoy steaming in the rough direction of Bergen, around 40km from the right-hand edge of AN27.
Slightly frustrating to see all these juicy targets rolling on by and not being able to shoot at them without taking a renown hit!
<EDIT: seems like the flag was NORWEGIAN rather than Dutch (makes more sense; teach me to try and guess at flags from several KM away in the dark!), so have changed post to reflect>
