text: At 10:40 a.m., two escorts attacked a U-boat but it evaded the attack with a Pillenwerfer, a discharge of compressed air which gave the same Asdic echo as a submarine and the hunt was terminated at 1:00 p.m. Wireless contact was made with the homeward QP 14, ready for the changeover and then Scylla and the FDE departed, along with the Avenger group, Alynbank and the two submarine escorts.
