It's a crap shoot on whether or not they come after you. I've seen just the opposite where they don't even bother you and skedaddle without looking back.
Dive deep and move off a 1knot in Silent Running. Usually they'll stay in that one spot thinking you're still there. If you're at periscope depth and try to get them too, make sure you use a G7a set to it's highest speed and don't change it's depth. Then wait until they're within 600 meters. Fire and you should knock them off. But be warry of the others.... you've just stired up the hornests nest again.
