Pls help following a convoy

[howler93]

I fired my last three bow torps at some merchants. I sank one and damaged another. How do I stay close to the convoy (going SW) to avoid getting detected and then sink some more using my aft torps?

Are there any escorts? How fast is the convoy going now? If there ARE escorts and the convoy is moving faster than 8-9kts, I'd slink out of visual range (7-8miles?) and do and end around on the surface- repositioning your boat ahead of the convoy's course for a second attack.

Good luck and good hunting!
