The only exception to this was a ship I sunk many careers ago. I think it was a warship too. I lost all contact while evading at depth. When I surfaced, at over 11nm away, I picked them up on radar. A short time afterwards, I had all but given up on the damaged ship that got away. I was almost certain it would've sunk but, sure enough, I got the "She's Going Down Sir" report and a ship sunk icon appeared on the map (11nm away). I even had to check the Captain's Log because I couldn't believe it, but it was there, I got the credit. That was the weirdest encounter (only one of it's type) I ever had.
