Thank you for the welcome.
Yes i know flank is not to be used to get away. Nor, did i try to. I was always running at 1-2 knots the whole time. I just thought since i appeared to be very far away he would not hear me anymore. I was wrong in assuming that. Is there any certain way to tell when he has lost me? Also, i did not know that after a DC explosion the DD is deaf for 30 seconds. I only went from slow to flank when it was exploding. Then from flank to slow after all the explosions were gone. i didnt know i had an extra 30 seconds after that.
