氷川丸
"Truant" was assigned to operate in the Far East, against Japanese shipping in 1942. She was present for the beginning of the Battle of Badung Strait and spotted the Japanese covering force, launching an attack at the light cruiser "Nagara" but scored no hits, although the crew said to have heard two impact noises from dud torpedoes hitting the target. She sunk the Japanese merchant ships "Yae Maru" and "Shunsei Maru" in the Malacca Strait. She almost sunk a large liner, but held off as poorly displayed hospital markings were spotted (possibly the "Hikawa Maru"). A few days after she engaged in a gun battle with the Japanese army cargo ship "Tamon Maru No.1", which sank shortly after. This was her final patrol as she started to experience engine trouble.
