14.35 hrs, Bay of Biscay, inbound: Whitley bomber A for Apple on A/S patrol from RAF OTU Sqdn 10 sighted the boats wake from a distance of 2.5 miles, but had to lose height before carrying out an attack, making a starboard turn to approach from dead astern and dropping six depth charges set for shallow along the track 20 seconds after the U-boat dived.
