As the instructions say:
Kaleuns in 1st and 2nd flotillas are to run a 5 day shakedown patrol then dock at home port. Kaleuns in 7th are to stay inside the bay and sink target ships, 2 ship convoy and carry out shakedown drills, avoiding any damage. More orders will arrive by message on 4 Aug.
And on 1 Aug you receive the following message:
Welcome to GWX - Königsberg U-boats. You are to head West into the bay to carry out training. Along the way are 3 sets of targets. There is also a 2 ship convoy for simulated attacks. You may sink them all but be warned you will become the enemy of even your own country so press " ESC " to return to base when ordered to do so|GWX
If you attack any neutral ship in SH3 you become the enemy of all neutrals for 24 hours.
