"Single contact... Merchant... Moving fast... Closing"
Moving fast ? I thought to myself. Curious ...a few quick calculations left 30 degree rudder make course 320 all ahead full !
The orders were rang up and executed after a small period of time we had closed the distance to the contact. We made a note that the contact appeared to be alone as we had not picked up addittional contacts Not quite what we expected.
Up scope.. a quick scan and there it was A lone 'huge euro liner'

with the japaneese flag
Long story short we sunk her.
This was late in the war June of 43 I belive.
