Stalking the U-boat
, 172. An earlier sinking credited to the group was the result of a mistaken identification: on February 10 one of the Liberators attacked a U-boat believed to be
U-519
, which was shortly thereafter reported lost in the Bay of Biscay. In fact the boat that the aircraft attacked (and only slightly damaged) was
U-752
; the cause of
U-519
’s disappearance remains unknown, and was possibly accidental.
