Hello, I'm searching to find the ship to which belonged one German sailor listed by the Volksbund as having died in the Azov Sea on 9 July 1943, Obersteuermann Horst Grey.

I checked the war diary of Admiral, Black Sea (the Englih translation ) and found two possible ships:

1) MAL-8 was hit by Soviet coastal guns off Achuevski, on the coast of the Azov Sea north of the Kuban bridgehead, on the morning of 9 July 1943 and lost 2 KIA.

2) S-102 was sunk by a mine on the night of 8 July (actually the night of 7-8 July) and sank by 45° 4.5' N 36° 42.5' E with the loss of 8 crew. This was in the Black Sea, not the Azov Sea and one day earlier, but just in case I would like to check its crew losses too.

Thanks in advance
