On 30 October, from St. John's, Newfoundland, "Yorktown" had just completed recovering planes and was proceeding to refuel when, at 1219, "Anderson" made an underwater contact, distant. "Anderson" went to general quarters immediately and proceeded ahead to develop the contact dropping a standard pattern of six depth charges at 1225. Five minutes later, dropped an "embarrassing barrage". Other ships in the vicinity, however, began sighting porpoises and blackfish, leading Commander Frank G. Fahrion, Commander, DesDiv 3 in "Anderson", to report over the high-frequency radio (TBS) to "Morris" that, in view of the fish sightings, the contact was a false one.
