Hi Simon,
From a British file summarising Y-Service and ULTRA material, on 25 July 1942 an Arado 196 of 5./196 was attacked and damaged by a Whitley in approximately 48 N 8 W at 18:00. The Germans reported that the Whitley was also hit and an engine was set on fire. The German aircraft was heard from 18:00 to 18:58.
Cheers,
Andrew A.
