Ship sunk on map but not in log...

[9emini]

Context: I chased a couple of aux cruisers led by a Southampton-class from the Moray Firth to AN14. They were making 15kts so I got in close behind and loosed a couple of eels while targets were traveling straight. (Thought each would take at least 2 torps to sink - how wrong I was!) First eel hit rear ship while second did not. A wee while later I notice both aux cruisers are burning so conclude my second eel was also successful. To my amazement, both ships sink after a while with no further effort on my part. I get two 'ship sunk' icons on the map, but am dismayed to find only one of the cruisers is listed in the captain's log. Is it possible another u-boot took out the other cruiser? Would be an amazing coincidence (tho' I have reason to suspect another in the area thanks to a radio message I received near start of chase).

[chased light cruiser to AN12 and downed 'er with 2 torps and two cheeky deck gun firings :-) ]

On a related note: what a thrill to meet (for the first time) relatively large naval vessels with no real ability to deal with subs. Serpentining aside, the trio remained on-course throughout chase, and only fired on me if I got too close (<1500m). This following my downing of 12 swordfish (and loss of 3 flak gunners ) has helped make this my most memorable and rewarding (~55t so far) patrol ever - my first in the VIIB after the 7 IIA patrols it took to earn sufficient renown to upgrade.
