Italian naval actions in the Black Sea

[Aymeric]

Hello,
I'm looking for some datas about the italian actions in the Black sea in 1942 :

- on 10/06/1942, transport ship Abkhaziya was damaged by Mas 571 and then sunk by german bombers. Is that correct ?

- on 05/09/1942, Mas 568 damaged a russian merchant ship of 3000 tons. Is that correct ? I've found the date of 06/09/1942 too for this action...

I've already seen these websites :
