@Stiebler: Thanks very much for the code positions.
Unfortunately, I will also use the "contact report" button for a future "wolfpack" fix, as one can see here:

So in the future the player will have to decide: Surrender or Wolfpack (provided I succeed with that fix).
Is it really useless so far? I thought, you can get help of aircraft if you send a contact report.
