Hello jiri
One fellow that comes to mind who was involved in a similar incident as you describe was Oberfeldwebel Werner Quast:
7 August 1943: Oberfeldwebel Werner Quast of 4./JG 52 in Bf 109 G-6 "White 2" (W.Nr. 15 844) at Noworossijsk, 40 kilometers southeast of Anapa. Following ramming his victory crashed in sea, missing, probably prisoner of war.

Horrido!
