erm... we'll start with a regular class T at first then shall we ?
maybe the Zwaardvisch :
6 Oct 1944 at 06:53 hrs:
Zwaardvisch (1) attacks the German submarine
U 168 (+/- 1144t). The Dutch submarine fires six torpedoes, one torpedo hits the target and the U-boat sinks. 27 Germans survive the attack, but 23 men are lost. Position:
06°20'S-111°28'E, off North coast of Java.
According to German sources the German submarine was intercepted after the allies learned of its exact position, and time of arrival at several navigation points, through code breaking efforts.
