Well just recently I was playing about in Hartlepool on a new career in december 39 in a type 2. I'd fired my canoe's 5th and last eel into a C2 inside the harbour and we were on our way back out to sea submerged. It was night, clear sky and no wind to speak of, our hydrophone man had a destroyer on the line but it was at "long" range when this tiny trawler wanders infront of my bows at 1200m. Who could resist an after dinner mint?
"Blow balast", man the flack gun! About 5 magazines of 20mm ammo later and the little fishing boat sank becoming our final kill of the patrol. Exit for the Fatherland to the tune of "Mein Kleiner Gruner Kaktus"!
