Sunk with one fish!

Has anyone else managed to sink the huge european liner with just one torpedo?
I was on patrol off Honshu, mid june 1942, just SSE of Yokosuka, Hit her from about 2000m, torpedo depth of 20. The torpedo struck between the smoke stacks, 5 seconds later one huge explosion and "enemy unit destroyed" is reported, when the second fish I had launched hit home a few seconds later the liner took a noesdive and was completely below the waves within a minute.
