 "Ivan Papanin" had passed the area few hours earlier and likely having been warned of the presence of the Finnish submarine, it had altered its course to evade "Iku-Turso".In late December 1941 "Iku-Turso" patrolled for a couple of days off Liepāja but did not encounter any targets the rules of engagements would have allowed the submarine to attack.In January 1941 "Iku-Turso" patrolled four days off Saaremaa and Hiiumaa but without any luck.
