HMCS Arvida - she took in three major convoy battles, ONS 92 in May 1942, ON 127 in September 1942 and SC 107 in November 1942. During ONS 127 she rescued survivors from the sinking HMCS Ottawa which had been hit by two torpedoes. Convoy SC 107 was such a disaster that it contributed to Canadian escorts being pulled out as ocean escorts. While escorting convoy ON 188 in mid-June 1943, Arvida was damaged by her own detonating depth charges. She spent a week repairing in Iceland.
